Re: [Vala] swpan error won win32

[raum]

Hi,

In fact my version of vala makes Win64 binaries so I just put
gspawn-win64-helper-console.exe and all is now perfect.

(in fact I've read something about win32 gspawn when vala was linking my
project so I've thought that I've need gspawn-win32, ooops)

Regards

Raum

[Vala] swpan error won win32

[raum]

Hi,

I'm trying to launch a command with spawn_async_with_pipes unsuccessfully...

I've installed gspawn_console and helper executables in the same directory
of test.vala

--- test.vala ---

int main (string[] args) {

string[] spawn_args;
// spawn_args = { "a_soft.exe" };
spawn_args = {"dir"};
string[] spawn_env = Environ.get ();
Pid child_pid;

int standard_input;
int standard_output;
int standard_error;

try {

Process.spawn_async_with_pipes (null,
spawn_args,
spawn_env,
SpawnFlags.SEARCH_PATH ,
null,
out child_pid,
out standard_input,
out standard_output,
out standard_error);
 } catch (SpawnError e) {
 stderr.printf ("Error : %s\n", e.message);
}

return 0;
}
--

I've set on a cmd shell : set G_SPAWN_WIN32_DEBUG=1

I've launched valac with a lot ofd debug information about
vala_gspawn_console:
>valac test.vala -o test.exe
calling C:\Vala\bin\vala-gspawn-console.exe with argv:

and then launched test.exe and get :

Re: [Vala] Starting with Vala

[raum]

Hello,

I humbly tried to create some programs in Vala but I made a lot of
mistakes (especially on NPC which was my first "big" program that is
really not optimized, clean, etc. but has the merit to try something
complex)

http://www.github.com/Raumy

You could take a look to "check_fs" which is better and my lastest 
"graph_map".

Regards

Raum

Re: [Vala] How to draw on a pixbuf

[raum]

Hello,

I think I've found a solution :)
- create a Surface and get the context of this surface
- draw on the surface
- create a pixbuf from the surface
- copy pixbuf into my drawingarea !

SOURCE CODE :

using Gtk;
using Cairo;

public static int main (string[] args) {
Cairo.ImageSurface surface;
Cairo.Context cr;

surface = new Cairo.ImageSurface (Cairo.Format.RGB24, 100, 100);

cr = new Cairo.Context (surface);

cr.paint();
cr.set_source_rgb (1, 1, 1);
cr.rectangle (0, 0, 100, 100);
cr.fill ();

cr.set_source_rgb (1, 0, 0);
cr.rectangle (10, 10, 40, 40);
cr.fill ();
cr.move_to(0, 0);
cr.line_to(100, 100);
cr.stroke();

Gdk.Pixbuf result= Gdk.pixbuf_get_from_surface(
surface, 0, 0, 100, 100);

Gtk.init (ref args);
var window = new Window();
window.title = "First GTK+ Program";
window.border_width = 10;
window.window_position = WindowPosition.CENTER;
window.set_default_size (400, 400);
window.destroy.connect (Gtk.main_quit);

DrawingArea da = new DrawingArea();

window.add(da);

da.draw.connect ((context) => {
Gdk.cairo_set_source_pixbuf (context, result, 0, 0);
context.paint ();
return true;
});

window.show_all ();

Gtk.main ();


return 0;

}

[Vala] How to draw on a pixbuf

[raum]

Hello everyone,

I want to prepare a picture and paste in a drawingarea, so I thought I
should draw on a pixbuf, then copy it to my drawingarea

I've create a drawing area (500x500) and I've tried this code in "on_draw" :
public bool on_draw(Widget da, Context context) {
(...)
var pixbuf = new Gdk.Pixbuf (Gdk.Colorspace.RGB, false, 8, 100, 100);
Surface s = Gdk.cairo_surface_create_from_pixbuf (pixbuf, 1, null);
Context c = new Context (s);
c.move_to(0, 0);
c.line_to(50, 50);
c.stroke();

Gdk.cairo_set_source_pixbuf (context, pixbuf, 0, 0);

context.paint ();
(...)

But the result is a partially black rectangle with some with points

Have you some advices ? :)

Thanks.

[Vala] How to get drag'n drop picture from Firefox ?

Hello all,

I've tried to send yesterday a mail but I didnt received a notification,
so please excuse me if you have this message on double... ^_^

I'm trying to get an picture and its URL from Firefox by 'drag & drop'
into my vala application

I only have the URL link "pointed by"  the picture and I think I've missed
something with targets list ... (I've got some hints from

Do you have some hints to retrieve picture and URL pointed by this picture ?

[Vala] Just a news I've read about popularity langage

[raum]

Hello,

I've read this news :

http://redmonk.com/sogrady/2016/07/20/language-rankings-6-16/?

And if you look at this picture, you will see that Vala is here :)
http://sogrady-media.redmonk.com/sogrady/files/2016/07/lang.rank_.Q316.plot-WM.png

As I understood, a lot of projects on GitHub and, because Vala is great
(wink) less demand on Stack Overflow ^___^  (well, it's a joke :) But I
think a lot of questions have been asked through this mailing list instead
of StackOverflow)

Just to share my hapiness to see Vala, for once, in a chart and finally in
a good position... ^__^

Re: [Vala] Get CREATION DATE OR TIME of file

[raum]

Hi,

Problem between windows and linux API,  probably...

Either you can take a look to one of my project wich worked on linux

ink.net   Sent: Tuesday, 28 July 2015, 1:40   Subject: Re: [Vala] Simple 
filewalker code.  Comments? Well, part of what I was looking for was 
stylistic pointers.    The Wiki Vala hacking page has a style guide:  
https://wiki.gnome.org/Projects/Vala/Hacking#Coding_Style  and Elementary OS 
write their apps in Vala and they seem  to be using similar:  
https://elementary.io/docs/code/reference#code-style  Although Yorba take a 
different approach:  https://wiki.gnome.org/Apps/Geary/CodingConventions   
That's code formatting style, but also Vala is seen  generally as an object 
oriented language so you want  to be thinking about classes and interfaces. 
Starting to  get an understanding of design patterns by the so-called  Gang 
of Four and also the SOLID principles helped me. This is  the first 
thing I've written in vala.  Partially, the find command is   less than 
optimal because I want to include the code within another   program.    I 
use find and it took a while for me to get to grips with it  so I thought I 
would share a tip based on what I use. Many languages include a simple 
filewalking approach, and I   was somewhat surprised that I couldn't find one 
within vala, so   partially I was looking for a pointer to a library that I 
had overlooked.That's interesting, for low level stuff GLib is often the 
firstplace to look. The best I could find was this StackOverflow answer  
http://stackoverflow.com/questions/2217519/how-to-walk-a-directory-in-c  One 
answer pointed to GFileEnumerator. Code examples on Valadoc:  
http://valadoc.org/#!api=gio-2.0/GLib.FileEnumerator  but not recursive from 
what I can see.  And partially I was looking for pointers as to where 
the community  recommended that beginners post code and look for tips. 
I haven't been really pleased by the documentation of vala that I could   
find, so I was hoping that there was someplace better than the mailing   
list...and a bit over 24 hours for the first response isn't   encouraging.  
OTOH, the civil response *is* encouraging.  ValaDoc is   greatly improved 
over the last time I investigated vala, but many things   still seem to 
assume that you are coming from a background of C   coding...and that you 
remember the C libraries.  My most recent   background is Python and D, so 
I'm often left in confusion until I dig   back deeper...which slows 
everything down. You could try StackOverflow:  
http://stackoverflow.com/questions/tagged/vala   One of Vala's key points is 
its strong compatibility  with C. This enables a lot of libraries to be used 
in  a modern object oriented way without having to rewrite  the libraries. 
This does mean though you may have to start  a search with how something is 
done in C, often GLib,  and then see if their is a Vala translation.
Being able to recognise some basic C interfaces has a  lot less cognitive load 
that trying to write good,  scalable code in C.   As to response times that 
is a function of the number  of people you are addressing and whether your 
question  piques their interest. The larger the community the more  chance of 
getting someone's interest and they will then  take the time to write a 
response. Vala certainly has a  smaller community than Python.

I'm hoping someone will tell   me if    this is the correct approach.  
  correctness depends on your criteria. You say it works so it is   
correct.  If on the other hand you want to be productive. Why 
reinvent the wheel?    Why not just use something like the 'find' command 
line tool, e.g.    find ./ -type d -exec du --human-readable '{}' \;    
will apply the disk usage command to each file in the current directory.    
It is a trivial example that just shows how much space each file takes up.   
   If you want to create a program with a bit more flexibility. Create a  
  list of file paths in the first step. Then apply a filter function    to 
each path, so you would use this to remove directories and then    another 
filter function to remove symlinks, as per your current program.    This 
allows you to add other filters later.    Once you have a good list iterate 
over it and call your function, or   functions    if you add more in 
future, with the file path as the parameter.  For a list exmaple see: 
   

[Vala] Network Packet Cleaner

[raum]

Hello,

I've informed you monthes ago that I was trying to code an application
that graphically manipulate a pcap file (removing hosts, connections or
sessions, etc.) using Vala.

I'm sorry to say I don't have enough time to get a good version.

So I've uploaded all my code to github.
https://github.com/Raumy/libnetframes
A library which contains various classes to handle a pcap file.
You could use this library in stand alone for others applications.
- It uses : tshark, libpcap.
- It should : compile under Linux and Windows.
See examples directory.

https://github.com/Raumy/npc
the original graphical application, using GTK and libnetframes.
You should add the directory where libnetframes is located to your lib
path if you want to execute npc.

Under Windows, you need to install mingw32 and a lot of files... :)

I've some difficulty to make the Data Exchange Chart...

You can use this code as example or contribute, or give me advice for a
better code.

Some comments in my code are in french, sorry ;)

[Vala] Performance issue

[Raum]

Hello

I'm developping a tool which graphically display a pcap file.

I'm using treeview / TreeModel / TreeStore to show a lot of frames information 
and I've some performance issues... notably on navigator view.

Is there any optimization tool (under linux) ? (which can give me some 
informations where I should optimize my code ?)

If you want to experiment the lags, check version 1.4 on
https://sourceforge.net/projects/netpackclean/   and give me your opinion

Re: [Vala] Recursive foreaching

Hello

I've tried something like that (In fact I've began to code a turn based
game... ehm... well ok... I'll explain in the future)

It's my first attempt in vala :
https://sourceforge.net/projects/valatreeobjects/files/

Really perfectible but  it's fun.

I'll try to clean up my code and use vala's best practices later (or if
someone want to have a look ;))

 I have a tree of nodes, something like this in pseudocode:
 class Node
   ArrayList kidnodes
   Node parent

 So - each node has kids and a parent.

 I find myself wanting to foreach over the tree from code that is not
 within a Node.

 Right now, I'm doing this kind of thing:

 class Node
...
public void walk( somelist)
  foreach(kid in kidnodes)
somelist.add (kid) //visit.
walk( somelist )

 Then, in some other object:
 var list = somelist
 somenode.walk(l)
 //now i can foreach through list

 Is there some way I can do:

 somenode = rootnode; //say
 foreach( node in somenode)
visit(node)

 so that it visits the nodes like walk does?

Hello,

I'm proud to present my Packet Cleaner tool ! (ehm no imagination for a
good name so it's Network Packet Cleaner :-/)

I've asked a lot of questions about how to handle files, how to use GTK,
etc... and I wanted to show you the conclusion.

I'm not sure I've the right to include tshark in my binary package... :-?

Linux binary certainly at the end of day... For source code, I need to
clean and document them ;)

It was'nt so complicated to create this tools and I'll see to add a DEC

[Vala] How to convert a string to float ?

[raum]

Hello,

Just as I said in subject of this mail, I'm trying to convert a string
into a float.

To convert a string to int : int.parse
ok, easy...

Float... ehm.. no atof function, I've seen a lot of things about Value
so I've tried and I've got  GLib-GObject-CRITICAL **:
g_value_set_***...

So how can I convert ?

Sample code :
Value val = Value (typeof (double));
val.set_string(3.4);   //  error
stdout.printf (get_double()\n);
stdout.printf (%f\n, val.get_double());
stdout.printf (get_string()\n);
stdout.printf (%s\n, val.get_string()); // -- error

Value val2 = Value (typeof (string));
val2.set_string(3.4);
stdout.printf (get_double()\n);
stdout.printf (%f\n, val2.get_double()); // -- error
stdout.printf (get_string()\n);
stdout.printf (%s\n, val2.get_string());

OUTPUT :
---
(spawn.exe:4056): GLib-GObject-CRITICAL **: g_value_set_string: assertion
`G_VALUE_HOLDS_STRING (value)' failed
get_double()
0.00
get_string()

(spawn.exe:4056): GLib-GObject-CRITICAL **: g_value_get_string: assertion
`G_VALUE_HOLDS_STRING (value)' failed
(null)
get_double()

(spawn.exe:4056): GLib-GObject-CRITICAL **: g_value_get_double: assertion
`G_VALUE_HOLDS_DOUBLE (value)' failed
0.00
get_string()
3.4
---

Re: [Vala] Header file not found ?!?

 Hello,

 This isn't likely to have much effect?Vala uses C, not C++.  You may
 have better luck with CFLAGS.  AFAIK Vala doesn't use the CFLAGS
 environment variable, though, so if that's what you're hoping will pick
 it up I think you're out of luck.

 If you want to get valac to pass specific C flags to the C compiler, use
 -X (valac -X -I/opt/include ...).

 C_LIBRARY_PATH=/usr/include:/mingw/include:/opt/include

 simple vala code test_pcap.vala :
 -
 void main() {
  stdout.printf (%s\n, PCap.get_version());

 }
 -

 Command to compile test code :
 $ valac --pkg gio-2.0 --pkg libpcap  test_pcap.vala
 d:/test_pcap.vala.c:8:23: fatal error: pcap/pcap.h: No such file or
 directory
 compilation terminated.
 error: cc exited with status 1
 Compilation failed: 1 error(s), 0 warning(s)
 $

 Do you have an advice ? I don't understand why valac didn't find a file
 which is obviously present in /opt/include/pcap/ folder ?

 It's actually not valac which doesn't find the header file, it's the C
 compiler.  You can always just tell valac to compile to C but not
 compile the C itself (using the -C flag), then invoke your C compiler
 manually.  Once you figure out the right flags, you can pass them to
 valac with -X.  You can also see what flags valac is passing to the C
 compiler with something like `valac --cc=echo --pkg gio-2.0 --pkg
 libpcap test_pcap.vala`.

 Yes, you would need to create VAPI.  I looked at the 7zip SDK API quite
 recently and I don't think creating a VAPI would be an easy task.  The
 API is a bit of a mess.

 I'm not sure what your use case is.  If you need to read and write *.7z
 files you might want to look at libarchive?I'm not sure whether they
 support 7zip or not, but if they do then it would be a much easier way
 to go since it already has a VAPI.

 If you just want to compress stuff you might want to take a look at a
 project I've been working on called Squash [1], which does have Vala
 bindings.  It is an abstraction layer for compression libraries (not
 archivers?that's what libarchive is for), and it supports most of the
 algorithms 7zip uses.

 I do plan to write a Squash plugin for the 7zip SDK eventually [2], and
 if you really need PPMD, BCJ, or BCJ2 (Squash already supports LZMA,
 LZMA2, bzip2, and DEFLATE) I can take a look at that sooner rather than
 later, but keep in mind that it will not support *.7z archives.

 Also, if you're not tied to 7zip, you may want to look at FreeArc [3].
 I don't remember if they have an API you could use or not, but the PPM
 compression is better, and the other algorithms are great [4].  Or, if
 all you care about is compression ratio, ZPAQ [5] (for which there is a
 Squash plugin) is amazing.

 libarchive is not GObject-based, so it's not possible to generate a vapi
 automatically.  Writing it by hand is your only option.

 libarchive 3 is compatible with previous versions, so there is no need
 to create a new VAPI.  Just add what you need to the existing bindings.

 You have to add things you want to extract from the FileInfo on the line

$ test

Thanks

 You can also use int64.FORMAT like this:

 stdout.printf (val1: +int64.FORMAT+\n, val1);

 This is because stdout.printf is using libc's fprintf function, instead
 of the glib one. The windows libc uses the %I64d format instead of
 %lld, so it fails.

 Use the portable way instead, or just use glib format functions only.

Int64 is correctly disdplayed with %lld format, int is not correctly

 If you use the wrong format string you are going to display wrong data.

 This is, windows is 32bit, and values are pushed on the stack from 4
 bytes to 4, if the printf format expects a 64bit value it will fetch 4
 bytes from the value and 4 bytes more from the stack (which can be zero
 or any other value) causing the output you see.

 Please, use the proper format string.

 You can see the C code to verify if the compiler does it right, but you
 didnt provided the valac version and I doubt vala can do such a simple
 operation wrong.

I've read too fast your first answer, sorry... (and english is not my

Ok, well, thanks a lot :)

Raum

 Nope, it is not strange, it is what it should be.

 %lld is not valid on windows, so it is taken as %d. so if you dont use
 the right format windows will execute this:

stdout.printf (val6: %d, val7 : %d\n, val6, val7);

 instead of

stdout.printf (val6: %lld, val7 : %d\n, val6, val7);

 What happens here is that %d will get the first 4 bytes of val6 and the
 second %d will get the next 4 bytes of val6. Resulting in 96 and 0.
 (little endian matters here).

 So again, please use the correct, portable format strings. %lld is not
 portable. It will work on all known unixes, but fail on windows because
 they use %I64d.

  int val7 = (int) (val6 / 8);
  stdout.printf (val6: %lld, val7 : %d\n, val6, val7);
  stdout.printf (%d\n, val7);
 }

 output :
 $ a
 val6: 96, val7 : 0
 12

 Int64 is correctly disdplayed with %lld format, int is not correctly
 displayed at first.

 Strange ? isn'it ? :)

 But ok, I've got the right value.


 generated C code :
 /* a.c generated by valac 0.20.1, the Vala compiler

 If you use the wrong format string you are going to display wrong data.

 This is, windows is 32bit, and values are pushed on the stack from 4
 bytes to 4, if the printf format expects a 64bit value it will fetch 4
 bytes from the value and 4 bytes more from the stack (which can be zero
 or any other value) causing the output you see.

 Please, use the proper format string.

 You can see the C code to verify if the compiler does it right, but you
 didnt provided the valac version and I doubt vala can do such a simple
 operation wrong.

[Vala] Int64 operations, I'm confused

[raum]

There is something I do not understand. I try to make a simple operation
and here is the result.
(...)
int64 val1 = 96;
int64 val2 = val1 / 8;
stdout.printf (val1: %lld, val2 : %d\n, val1, val2);

int val4 = 96;
int val5 = val4 / 8;
stdout.printf (val4: %lld, val5 : %d\n, val4, val5);

(..)

Results :
val1: 96, val2 : 0
val4: 96, val5 : 12

In fact I want to use file.query_info() which returns an int64 for size
(actually 96 bytes). And I need to divide size by 8 result = 0

Any advice ? :)

Thanks

int64 val2 = val1 / 8;

int val4 = 96;

int64 val6 = 96;
int val7 = (int) (val6 / 8);
stdout.printf (val6: %lld, val7 : %d\n, val6, val7);
(...)

Results :
val1: 96, val2 : 0
val4: 96, val5 : 12
val6: 96, val7 : 0

I'm using valac under Windows, using MingW.



 You've not hit an issue with using lld have you?

[Vala] How track memory leaks ?

[raum]

Hello,

I wondered if it 's possible to recover memory information or memory leaks
 other than mem_set_vtable(mem_profiler_table); and without using a
third party software like valgrind ?

Thanks

 This is a bug in vala, see

 The workaround is to initialize your ArrayList in the constructor:

 public cAbstractObject () {
  _objects = new ArrayListG ();
 }

Hi,

Then launch msys.bat

It seems to work but with a long program, which launches, it crashed

Re: [Vala] How to compile Vala using MingW under Windows

[raum]

Hello,

Thanks but it's not related to libraries declaration under Windows but
how I missed something when I've compiled Vala 0.18... or something
related to PATH

I think I should try to recompile and reinstall...

Thanks

Regards

Raum

 I learned that under Windows you need to provide some extra info about
 libs
 you're using.

 For linux I have this:
 valac -o Game --pkg gee-1.0 --pkg gl --pkg libglfw --pkg glu --pkg
 libxml-2.0 --pkg gio-2.0 \
 ... (other lines, source files mostly)

 For Windows:
 valac -o Game --pkg gee-1.0 --pkg gl --pkg libglfw --pkg glu --pkg
 libxml-2.0 --pkg gio-2.0 \
 -X -lglfw -X -lopengl32 -X -lgee -X -lglu32 -X -lxml2 \
 --cc=gcc \
 ... (other lines, source files mostly)

 I don't remember exactly why I had to specify cc, but as there I have it,
 I
 thought to keep it here as well :)

 I have few other things that work differently on Windows and Linux (so I
 have ifdef here and there) but that might be related to mess I have on
 both
 systems (I tend to update vala quite randomly, same goes for other
 packages
 and those are the results)

 That's something related to gcc if I'm not wrong. Before using valac,
 ensure that your gcc is working correctly.

Well... i've installed python 2.5 and set PYTHON variable before ./configure

On MSYS console (I've installed python in d:\utils\python25)

# export PYTHON=/d/utils/Python25/python
# export LIBFFI_CFLAGS='-I /mingw/lib/libffi-3.0.11/include'
# export LIBFFI_LIBS=-lffi
# export CFLAGS=-O0 -g -pipe -Wall -march=i686 -mms-bitfields -mthreads
./configure --prefix=/build --with-pcre=internal --enable-silent-rules
--disable-modular-tests
# make
# make install

and it's ok...

 In fact, I've got Hello,

 I've tried to compile libgee but it depends to glib... :-/

 So, how to compile glib for Vala ?!?

 Reference site : http://www.mingw.org/wiki/Bootstrapping_GLIB_with_MinGW

 For information, I've relocated my precdedent vala-src directory in
 /src directory. I've modified msys/etc/fstab to :
 c:/vala-build/mingw  /mingw
 c:/vala-build/vala-0.18  /vala
 c:/vala-build/src /src
 c:/vala-build/mingw/lib  /usr/lib
 c:/vala-build/build /build

 1/ Install few more libs

 At first, we need to install these packages :
 libstdc++-4.6.2-1-mingw32-dll-6.tar.lzma
 libgcc-4.6.2-1-mingw32-dll-1.tar.lzma (for libgcc_s_dw2-1.dll)
 mmingwrt-3.20-mingw32-dev.tar.gz (for  crt2.o)
 libz-1.2.7-1-mingw32-dev.tar.lzma
 libz-1.2.7-1-mingw32-dll-1.tar.lzma
 gettext-0.18.1.1-2-mingw32-dev.tar.lzma
 gettext-0.18.1.1-2-mingw32-bin.tar.lzma
 libgettextpo-0.18.1.1-2-mingw32-dll-0.tar.lzma (for
 libgettextsrc-0-18-1.dll)
 libexpat-2.0.1-1-mingw32-dll-1.tar.gz

 (some links :
 http://sourceforge.net/projects/mingw/files/MinGW/Extension/zlib/zlib-1.2.7-1/libz-1.2.7-1-mingw32-dev.tar.lzma/download
 http://sourceforge.net/projects/mingw/files/MinGW/Extension/zlib/zlib-1.2.7-1/libz-1.2.7-1-mingw32-dll-1.tar.lzma/download

 )

 2/ Compile  install FFI lib from tarball

 And glib need libffi, so we need to download libffi package.

 FFI stands for Foreign Function Interface. A foreign function interface
 is the popular name for the interface that allows code written in one
 language to call code written in another language.

 Link : ftp://sourceware.org/pub/libffi/libffi-3.0.11.tar.gz
 (alt link:
 http://ftp.gwdg.de/pub/linux/sources.redhat.com/libffi/libffi-3.0.11.tar.gz)


 # cd /src/libffi-3.0.11/
 # ./configure --prefix=/build
 # make
 # make install

 Then move files into c:/vala-build/mingw.

 3/ Compile  install glib

 Download lastest release and extract to c:/vala-build/:
 http://ftp.gnome.org/pub/GNOME/sources/glib/2.34/glib-2.34.0.tar.xz

 And now :

 # cd /src/glib-2.34.0

 // I don't want to use pkg-config for libffi
 /src/glib-2.34.0# export LIBFFI_CFLAGS='-I
 /mingw/lib/libffi-3.0.11/include'
 /src/glib-2.34.0# export LIBFFI_LIBS=-lffi
 /src/glib-2.34.0# export CFLAGS=-O0 -g -pipe -Wall -march=i686
 -mms-bitfields -mthreads
 /src/glib-2.34.0# ./configure --prefix=/build --with-pcre=internal
 --enable-silent-rules --disable-modular-tests --disable-static

 (perhaps we need these variables...not sure)
 export CPPFLAGS=-DG_ATOMIC_OP_USE_GCC_BUILTINS=1
 export LDFLAGS=-Wl,--enable-auto-image-base
 export lt_cv_deplibs_check_method=pass_all
 ()


 /src/glib-2.34.0# make

 /src/glib-2.34.0# make install

 And that's

 Hi,

 Feel free to help me to improve (or correct ;-) ) this mini how-to and
 report if something doesn't work.

 Next step, I think I'll try to bundle clang... :-?

Ok, so which one ? the traversable thing is implemented since Libgee
0.7.. :-?

And a thing which also irritates me (sorry...), it is to see the
documentation referring now to the version 0.8...
http://valadoc.org/libgee-0.8/index.htm

[Vala] How to compile glib using MingW under Windows

[raum]

Hello,

I've tried to compile libgee but it depends to glib... :-/

So, how to compile glib for Vala ?!?

Reference site : http://www.mingw.org/wiki/Bootstrapping_GLIB_with_MinGW

For information, I've relocated my precdedent vala-src directory in
/src directory. I've modified msys/etc/fstab to :
c:/vala-build/mingw /mingw
c:/vala-build/vala-0.18 /vala
c:/vala-build/src /src
c:/vala-build/mingw/lib /usr/lib
c:/vala-build/build /build

1/ Install few more libs

At first, we need to install these packages :
libstdc++-4.6.2-1-mingw32-dll-6.tar.lzma
libgcc-4.6.2-1-mingw32-dll-1.tar.lzma (for libgcc_s_dw2-1.dll)
mmingwrt-3.20-mingw32-dev.tar.gz (for  crt2.o)
libz-1.2.7-1-mingw32-dev.tar.lzma
libz-1.2.7-1-mingw32-dll-1.tar.lzma
gettext-0.18.1.1-2-mingw32-dev.tar.lzma
gettext-0.18.1.1-2-mingw32-bin.tar.lzma
libgettextpo-0.18.1.1-2-mingw32-dll-0.tar.lzma (for libgettextsrc-0-18-1.dll)
libexpat-2.0.1-1-mingw32-dll-1.tar.gz

(some links :
http://sourceforge.net/projects/mingw/files/MinGW/Extension/zlib/zlib-1.2.7-1/libz-1.2.7-1-mingw32-dev.tar.lzma/download
http://sourceforge.net/projects/mingw/files/MinGW/Extension/zlib/zlib-1.2.7-1/libz-1.2.7-1-mingw32-dll-1.tar.lzma/download

http://sourceforge.net/projects/mingw/files/MinGW/Base/gettext/gettext-0.18.1.1-2/gettext-0.18.1.1-2-mingw32-dev.tar.lzma/download
http://sourceforge.net/projects/mingw/files/MinGW/Base/gettext/gettext-0.18.1.1-2/gettext-0.18.1.1-2-mingw32-bin.tar.lzma/download
http://sourceforge.net/projects/mingw/files/MinGW/Base/gettext/gettext-0.18.1.1-2/libgettextpo-0.18.1.1-2-mingw32-dll-0.tar.lzma/download
)

2/ Compile  install FFI lib from tarball

And glib need libffi, so we need to download libffi package.

FFI stands for Foreign Function Interface. A foreign function interface
is the popular name for the interface that allows code written in one
language to call code written in another language.

Link : ftp://sourceware.org/pub/libffi/libffi-3.0.11.tar.gz
(alt link:
http://ftp.gwdg.de/pub/linux/sources.redhat.com/libffi/libffi-3.0.11.tar.gz)


# cd /src/libffi-3.0.11/
# ./configure --prefix=/build
# make
# make install

Then move files into c:/vala-build/mingw.

3/ Compile  install glib

Download lastest release and extract to c:/vala-build/:
http://ftp.gnome.org/pub/GNOME/sources/glib/2.34/glib-2.34.0.tar.xz

And now :

# cd /src/glib-2.34.0

// I don't want to use pkg-config for libffi
/src/glib-2.34.0# export LIBFFI_CFLAGS='-I /mingw/lib/libffi-3.0.11/include'
/src/glib-2.34.0# export LIBFFI_LIBS=-lffi
/src/glib-2.34.0# export CFLAGS=-O0 -g -pipe -Wall -march=i686
-mms-bitfields -mthreads
/src/glib-2.34.0# ./configure --prefix=/build --with-pcre=internal
--enable-silent-rules --disable-modular-tests --disable-static

(perhaps we need these variables...not sure)
export CPPFLAGS=-DG_ATOMIC_OP_USE_GCC_BUILTINS=1
export LDFLAGS=-Wl,--enable-auto-image-base
export lt_cv_deplibs_check_method=pass_all
()


/src/glib-2.34.0# make

/src/glib-2.34.0# make install

And that's probably all...

Have fun

-- if [ $MSYSTEM == MINGW32 ]; then
--   export PATH=.:/usr/local/bin:/mingw/bin:/bin:$PATH
-- else
--   export PATH=.:/usr/local/bin:/bin:/mingw/bin:$PATH
-- fi

And now, just double click on msys.bat

my_machine# cd /vala-src
my_machine:/vala-src# ./configure --prefix=/build --disable-vapigen
(...)
my_machine:/vala-src# make
(...)
my_machine:/vala-src# make install

And that's all... If you want to test your new fresh install, just change
PATH variable.

tips: --disable-vapigen to avoid sys/wait.h fatal error when compiling

 Result :

test2
 Hello world!

 Where am i wrong ?

 Thanks !

 I forget the exact magic needed for mingw, maybe you need to add -X
 -mwindows to the command line?

 If not, add --verbose to your vala commandline and post the full gcc
 commandline that's being used, that may be useful

Re: [Vala] undefined reference to 'SDL_Init' and/or 'WinMain@16' (under Windows)

Well, I've tried but I've got the same error.

SDL package : SDL-devel-1.2.15-mingw32.tar.gz
(copy files from tarball to directories include, lib and bin).

To correct a -lcom32dlg error, I've installed :
http://sourceforge.net/projects/mingw/files/MinGW/Base/w32api/w32api-3.17/w32api-3.17-1-mingw32-dev.tar.lzma/download
(copy files from tarball to directories include, lib and bin).

 Hello,

 2012/3/20  r...@no-log.org:
 Perhaps a basic linkage error but I dont know how to correct :D

 You should be looking at the SDL FAQ for Windows:
 http://wiki.libsdl.org/moin.cgi/FAQWindows

 For example this question seems to be exactly what you want (don't
 forget -X before each argument):

 I get Undefined reference to 'WinMain@16'
 Under Visual C++, you need to link with SDLmain.lib. Under the gcc
 build environments including Dev-C++, you need to link with the output
 of sdl-config --libs, which is usually: -lmingw32 -lSDLmain -lSDL
 -mwindows

Ehm.. I don't have any idea or any clue

I've tried to create C code and compile it :
-
/* test2.c generated by valac 0.12.0, the Vala compiler
 * generated from test2.vala, do not modify */
#include glib.h
#include glib-object.h
#include stdlib.h
#include string.h
#include SDL.h
#include stdio.h

gint _vala_main (gchar** argc, int argc_length1);

gint _vala_main (gchar** argc, int argc_length1) {
gint result = 0;
SDL_Init ((guint32) 0);
SDL_Quit ();
fprintf (stdout, Hello world!);
result = 0;
return result;
}

int main (int argc, char ** argv) {
g_type_init ();
return _vala_main (argv, argc);
}
-

And I've got the same error (which is not surprising...) :

Re: [Vala] undefined reference to 'SDL_Init' and/or 'WinMain@16' (under Windows)

Really strange...

This code below is correct and a window appears !
==
using GLib;
using SDL;

int WinMain(string[] argc)
{
SDL.Surface *screen;

if( SDL.init( InitFlag.VIDEO )  0 )
{
stdout.printf( Impossible d'initialiser SDL:  %s\n,
SDL.get_error( ) );
return 1;
}


screen = SDL.Screen.set_video_mode( 640, 480, 16,
SurfaceFlag.HWSURFACE );
SDL.WindowManager.set_caption (Vala SDL Demo, );

if( screen == null )
{
stdout.printf( Impossible d'initialiser le mode video: %s\n,
SDL.get_error( ) );
return 1;
}

SDL.Timer.delay( 3000 );
SDL.quit();
return 0;
}


int main(string[] argc )
{
stdout.printf (not printed\n);

return 0;
}
=

The main function is not called and I've got two warnings :
Compilation time :
test2.vala:5.1-5.11: warning: method `WinMain' never used
int WinMain(string[] argc)

Linking time :
Warning: resolving _WinMain@16 by linking to _WinMain

I need to have these two function main and winmain... :-?

Ehm...

Thanks


 Hi
 WinMain usually is the entry point for Win32 programs (isntead of
 main()). If you do not have such a function defined in your C-Code you
 get the
 the error message you described. At least that's the experience I have
 with that error message with pure C an WinAPI

[Vala] undefined reference to 'SDL_Init' and/or 'WinMain@16' (under Windows)

[Raum]

Hi,

I'm testing Vala and I think I didn't understand how to use package with
it... I want to use SDL and SDLNet but I've got an undefined
reference...

Here is my test program :

using GLib;
using SDL;

int main (string[] args) {
SDL.init( 0 );

SDL.quit( );
stdout.printf (Hello world!);
return 0;
}


My command line to compile :
-
valac --pkg sdl test.vala
(...)\LOCALS~1\Temp/cconhiY1.o:test.vala.c:(.text+0x15): undefined
reference to `SDL_Init'
(...)\LOCALS~1\Temp/cconhiY1.o:test.vala.c:(.text+0x1a): undefined
reference to `SDL_Quit'
c:/vala-0.12.0/lib/libmingw32.a(main.o):main.c:(.text+0xbd): undefined
reference to `WinMain@16'
collect2: ld returned 1 exit status
error: cc exited with status 1
Compilation failed: 1 error(s), 0 warning(s)


But this sample below just compile without any error with the same command
line :
--
using GLib;
using SDL;

int main (string[] args) {
   stdout.printf (Hello world!);
   return 0;
}
--

Result :
---
valac --pkg sdl test2.vala

test2
Hello world!
--

Where am i wrong ?

Thanks !

Regards

Raum
