i like that, especially the way the paw print is done.  the way the
"project" is isolated and highlighted doesn't make much sense, though.
 what will it look like with the "lazarus" highlighted instead, and
the "project" below it without the highlight?

no, the last paragraph of the "What about .NET?" entry:

"These problems are pretty much similar for the Java (bytecode) too.
One has to mutilate the language, and rewrite the libraries from
scratch on the base libraries of the target (Java/.NET). Such an

today."

to compile lazarus with a specific version of fpc, i usually go:
make all FPC=/path/to/fpc/version/ppc386

make sure that your fpc.cfg is configured so that the different
versions of fpc can find their respective units.

it doesn't help just changing the subject.  if you look at the headers

there's a lot of image stuff built into fpc already.  look in
packages/fcl-image/src/ drawing.pp for inspiration.

alternatively (lazarus), you can just drop a timage on your form, draw
what you like, then save to a file with image.picture.savetofile().

i'm no expert, but you can already do this.  there's target os and cpu
comboboxes in the compiler options.  for this to work you also need to
set your compiler filename for it to use your cross compiler.

it would be quite handy to have all the settings in one place, but you
run the risk of creating a very schizophrenic gui (like almost

svn should take care of this if you set the eol-style property to

to emulate floating point instructions, or does this device have a
floating point unit?  if not, you'll have to compile everything with
-CfSOFT.

which version of fpc are you using?  my lcl compiles fine for gtk2 and

you shouldn't have to do this.  i dunno about how to do it in the ide,
but i get mine to compile by:

make lcl LCL_PLATFORM=gtk2 CPU_TARGET=arm OS_TARGET=linux
BINUTILSPREFIX=arm-linux- CROSSBINDIR=/opt/slugosle/bin
FPC=/usr/lib/fpc/2.3.1/ppcrossarm OPT="-CfSOFT"

you don't need all these options, but it gives you an idea what's possible.

Yes, it's nice to have FPC for that device, it would be perfect to be

at leas this is no: "Gtk-WARNING **: cannot open display:"
so you now have your display and ran into a complete different problem.

   Exception=Invalid Filer Signature:
maybe some endian issue or a corrupt file or a bad compiled string
constant (the form layout is stored internally in a string)


does this viper run a big or little endian kernel?  my vulcan is big

up to several seconds, before the button is drawn at the new position.
The top/left property (OI) of the button change immediately while

That makes lazarus SAD instead of RAD :)

Gtk2 interface has improved a lot, but IMHO it's still not really
usable ..


my biggest problem is what we're seeing here, i think.  the gtk2
interface is still really sensitive to changing window managers and
themes.  it crashes badly on icewm for me, but metacity works a treat.
i think the compiled programs are mostly o.k. (although i did have
crashes with messagedlg on certain themes).

another pain is the form designer, which doesn't let you select tabs
properly and (from today for me) won't let me move my combobox around.
i can set the properties in the o.i., though.

just for the record, which distro and window manager are you using?


So for now, I am switching back to gtk1.

Yeah, my personal experience with the GTK2 interface wasn't great
either. I'm back to GTK1, but now I have another issue. With all the
GTK2 changes, it breaks GTK1 from time to time. I'm now getting way
less updates for Lazarus due to this. Once I get a revision that works
for me, I keep it for a few weeks.

PS:
 I'm not knocking the GTK2 interface developers. :) You guys are doing
a great job. The GTK2 interface has improved a lot since a few months
back.  I would have loved to help , but the fpGUI framework is
keeping me to busy at the moment.



it's a bit hit and miss sometimes, but i think it's improved greatly.
i did hit a problem the other night when i tried to compile some win32
code under gtk2.  an onshow handler fired before something was shown
and caused a crash.  i'll look into that one if i get time.

i feel that the ide is quite usable in gtk2 (i wrote large parts of an
application with it).  most of my problems are due to my prolific use
of the pagecontrol/tabsheets, though.  i'd also love the gtk2
stringgrid to be a bit less sluggish and less flickery.  it takes me a
long time to understand the code, though, but i'm hoping to improve on
it someday.

i looked into this some time ago.  the function you really want to

all the locale files to populate big records with the correct
information.  these locale files are a libc invention to start with
(so the format might change, but unlikely) and they are not text
files!  so you have to look at ulrich drepper's code on what the data
structures look like and how to parse them (which are mostly macros,
by the way).

sorry for my hand-wavy description, but i didn't have enough time to
go into this at the time.  i keep telling myself there must be an
easier way and i wonder why those files aren't simply text files (like
everything else on linux).

I have a unit which does this for you. It checks the KDE international

because it creates a dependency on the C library, but I can send this

this was tested with icewm (theme gertplastic) and latest fpc.  i'll
try and test it with metacity to see if anything is consistent.  i've
had some problems with one of the ubuntu themes before, but haven't
tried the latest ones.



tested with metacity with some ubuntu theme and everything works o.k.
couldn't get to crash it at all - looks very nice indeed.

i haven't had problems with icewm at all, though.  any ideas to what
would cause the problems?

Here the Gtk 2 IDE crashes when I delete components from a Form. Can
anyone confirm before I post a bug report? (this would be the biggest

i can't reproduce that, but since i've tried head gtk2 interface 10
minutes ago, it's crashed about 10 times.  the alarming thing is that
it crashes my whole window manager and i have to go and kill -9 all
the processes :(

when i hit f12, the form doesn't show up.  i can find it in my window
list, but it won't bring it to the front.  the only way to find it is
when i minimise the editor window (usually).

also, the "View Forms" function causes a crash almost every time i try
and select a form to view (related to above?).  if i enable the
debugger, it crashes when the program finishes (almost every time...).

it seems a bit random, though, on the whole.  i'm sure other people
will be able to reproduce, though.  if i had to guess, i think many
crashes are due to showing/hiding windows.

Re: [lazarus] Wince Crossbin utils windows installer don't works

Hi ;)

I just downloaded and installed the new lazarus+crosswince but they don't
works.

The file I downloaded are:
Lazarus-0.9.23-fpc-2.1.3-20070424-win32.exe
Lazarus-0.9.23-fpc-2.1.3-20070422-cross-arm-wince-win32.exe

After installing, I opened lazarus and pressed F9 to compile a idle
project, it worked.

After changing target os and cpu to wince and arm (in al the three
comboboxes), I pressed control + f9 and got this errors:
project1.lpr(19) Warning: Object wincemenures.or not found, Linking may

project1.lpr(19) Error: Can't open object file: wincemenures.or
project1.lpr(19) Fatal: There were 1 errors compiling module, stopping

What I did wrong? Did I forgot something? The .21 version always worked
like that after an installation, without doing something else...



hi!  i had this problem the other day.  i got it to work by copying
the wincemenures.or to my project directory.  it should be in the
lcl/interfaces/wince/ directory.  you might have to re-compile the lcl
for wince if the file is not there.  this is probably not the right
solution, but it worked...

can anybody shed some light on this?  (or, even better, fix it)

What doesn´t work on Free Pascal is creating a dll that exports
classes, like for example building the full fpc runtime library into a
DLL. Exporting normal functions works ok.



yes, dlls do work with lazarus.  however, i've had a problem recently
(when using wince dlls) that lazarus wouldn't find them.  i think the
problem was that lazarus was trying to look for static libs.  the only
way i could fix it was to add -sh to the options and edit the ppas.bat
file (adding -l right at the end of the arm-wince-ld command
line).

that was strange, but usually it Just Works.

[lazarus] wince GetControlText

[Henry Vermaak]

when i try to use the "Text" property in the edit control as the text
in a MessageDlg function, it gives me a "Bus error or misaligned data
access" error.

i tracked this down to be the FreeMem(tmpWideStr) call in the
GetControlText function.  it makes sense to me to use the
SysFreeString function when you've used SysAllocStringLen - and when i
changed this to SysFreeString(tmpWideStr), it started working.  can
any wince geniuses confirm this?

this is on line 1135 in winceproc.pp.

i'd just like to quote an hilariously vague line out of msdn:

"Passing invalid (and under some circumstances NULL) pointers to this
function causes an unexpected termination of the application."

this is on the SysAllocStringLen page - a function which is supposed
to be able to handle a null param...

It´s funnny that I grew up at Piracicaba, country side of São Paulo

It´s more like the city of sugar cane. People sell the juice that

make sure that your libesd.so file is somewhere ld can find it (e.g.

`locate libesd`.  you might have to make a symlink if it's not called

Re: Problem with message handling

[Henry Vermaak]

hi gabor

the "event" function is there so you can give the handle to your event
(which you get from CreateEvent).  then you can create a thread that
blocks on this event with one of the wait functions
(WaitForSingleObject, for instance).  when the reader receives a scan,
it will set the event and your thread will resume and process the scan
buffer.

now this method is also platform specific, since the event functions
are in the windows unit.  can anyone comment on this for linux?  my
hunch is that a similar thing must exist...

Not necessarily, some gtk themes/engines are more 'robust' than others.
Reproduceability is important nevertheless, of course.

[lazarus] gtk2 showmessage error

Hello all

I've noticed something strange in one of my programs that I've compiled 
for gtk2.  When I call ShowMessage or MessageDlg (with mtInformation) 
the program crashes with an "Invalid floating point operation" error. 
(The program runs fine if compiled for gtk...).


The strange thing is that when I run the same program with MessageDlg 
with mtError, it works fine.  Can anyone confirm this, or is there 
something wrong with my setup?  (I'm running the latest snapshot lazarus 
with fpc 2.0.4 on Ubuntu, although the same happened on previous 
versions of lazarus and fpc).
