You have to install the -dev packages like gtk2-dev etc. the dev 
packages make the symlinks for you.

[Lazarus] Unit InterfaceBase

[Leandro Foly]

Hi, everyone.
I`m  getting the error "Can't find unit InterfaceBase used by Interfaces"
when I try to compile a simple project with Lazarus 0.9.26 under Windows XP
Home on an eeepc 901, 1024 of RAM.

I just installed by the exe-file downloaded from sourceforge, and tried to
compile, by pressing the green "play" button.

Some more details:
Lazarus Directory:   C:\InstLazarus\
Compiler path:c:\InstLazarus\fpc\2.2.2\bin\i386-win32\fpc.exe
FPC Source Directory:   c:\InstLazarus\fpc\2.2.2\source\
Make Path:C:\InstLazarus\fpc\2.2.2\bin\i386-win32\make.exe

Section Paths in Compiler Options is all blank.
Only LCL Widget Type (various) is assigned to "default (win32/win64)"

Thanks for the help.

[Lazarus] 0.9.26 (FPC 2.2.2) on Slackware and Debian

[Mark Morgan Lloyd]

I've set up a rather elderly Compaq here specifically for a number of 
jobs where I expect to have to wipe it and re-install if necessary. On 
it I have Slackware 12.1 and Debian "Lenny", largely so that I've got 
gtk2 etc.

If I install the binary of FPC 2.2.2 on Slackware I can compile Lazarus 
(both all and bigide) from source without problems.

If I do exactly the same on Debian I have to add libgdk-pixbuf-dev (no 
big deal) but then to get Lazarus to compile have to add a handful of 
symlinks:

libatk-1.0.so -> libatk-1.0.so.0
libpango-1.0.so -> libpango-1.0.so.0
libgmodule-2.0.so -> libgmodule-2.0.so.0
libgthread-2.0.so -> libgthread-2.0.so.0
libglib-2.0.so -> libglib-2.0.so.0
libgobject-2.0.so -> libgobject-2.0.so.0
libgdk-x11-2.0.so -> libgdk-x11-2.0.so.0
libgtk-x11-2.0.so -> libgtk-x11-2.0.so.0
libgdk_pixbuf-2.0.so -> libgdk_pixbuf-2.0.so.0

where

libgdk_pixbuf-2.0.so.0 -> libgdk_pixbuf-2.0.so.0.1200.11

etc.

I presume that this works on Slackware because the symlinks already 
exist, and can confirm:

libgdk_pixbuf-2.0.so -> libgdk_pixbuf-2.0.so.0.1200.9

and so on.

In both cases Lazarus runs, although not fast.

Now this is a completely virgin Debian system, it's never had 
Debian-served FPC or Lazarus packages installed and I've got a fairly 
good record of what's been put onto it and what changes there were in 
/usr/lib.

So would somebody please tell me what I'm doing stupid.

Indeed, since it was declared 'const' it will work *if* only one instance of 
this form is created.

I maintain that this should be a class member (variable). I believe those are 
all initialized to zeroes too, so you'll only have the set it to True to turn 
on your indicator.

Of course, do whatever you want in your code.  ;-)

But I cannot {:-(
As I described in  my first posting, the RPM for fpc 2.2.2 will not
install, because it wants glibc version 2.4, which is not available
for my Suse 10.0
That is why I wantend to work around it by building fpc from source...

Well, I read the build-faq (from march 17, 2007) entirely at least
once (as you suggest in it). Maybe I'm just not up to it.
Mind you, I don't mind trying, and even failing, as long as I don't
screw up my current stable Laz/Fpc configuration.

(I can hardly expect the person who builds the rpms to downgrade his
Linux so he/she can do the buildprocess against glibc-2.3 now, can I?)

[Lazarus] Default caption in MessageDlg()

[Bart]

I just noticed that if I do a

  MessageDlg('Some ErrorMessage', mtError, [mbOk], 0) ;

(so I do not specify a custom caption for the dialog) then the caption
of the dialog is the Application.Title, whereas in Delphi (at least in
D1 to D3) it depends on the DialogType, so in Delphi the caption of
the dialog in my example would be  "Error"

I just tested an existing executable, compiled with a previous version
of Lazarus, and this code:

MessageDlg(Format(msgSourceDirNotFound,
   [ExcludeTrailingPathDelimiter(SourceEdit.Text)]),
   mtError, [mbOk], 0);

will bring up a Dialog with "Error" as the caption.

I'm using Lazarus from SVN revision 16824.

Is this new behaviour by design (which would force me to rewrite
almost all my projects to use the MessageDlg(aMsg, aTitle, DlgType,
Buttons, HelpCtx) format instead), or is it a bug?

Re: [Lazarus] Commercial components for Lazarus

[Norman Schwirz]

I want to port some Programs written in Delphi to Lazarus/ Free-Pascal,
because there is no other way for further developing. The only other way
would be to completely rewrite it in another programming language.
:-(Thanks to Borland!)

So, I agree with Graeme and Michael too.

But I have an Idea: what do you think about a little (but continual)
contest of high-quality- programming?

Hi Tom,

I managed to detect this specific keyboard setting by:

var
  FResult: CFIndex;
  FValid: Boolean;

  FResult := CFPreferencesGetAppIntegerValue(CFSTR('AppleKeyboardUIMode'),
kCFPreferencesCurrentApplication, FValid);


FResult turn out to be bit flags:
  Bit 0 is set if feature is on
  Bit 1 is set if full keyboard access works for any control, not just text
boxes and lists

And these are of course flipped by:
  ^F1 flips bit 0
  ^F7 flips bit 1

Hope you can use this to detect the "Full Keyboard Access".

Best regards,
Normann

Same here, but our reasons were more being able to debug them in case of
problems.

Nowadays I hardly buy components. I use cport, indy9, VST and one routine
from dmath/fpmath and that is about it.

The main reason for that is that most components are not suitable for
systems where 10ms is a long time. (indy runs in a separate thread, since it
can also block longer, cport is async via windows msgs queues)

One of the components I had problems with was TeeChart. It was simply too slow
for us for everything except the slowest systems. (ate more than 300-400ms to 
draw
a simple chart, D7 version)

Ok, I'll try that then, but I haven some questions about how to proceed.
Some time ago I tried to build fpc from source on Windows. I did a
make cycle, and then a make install. This worked in the sense that I
now had a working compiler and fp IDE. However I never was able to use
this version with Lazarus, since the source-tree (from the tar
archive) did not remotely resemble the source-tree
\Lazarus\fpc\2.2.2\source, and I could not jump into the fpc source
(ctrl-click in the Lazarus IDE) anymore.

Firts the task of setting up a working fpc 2.2.2 from source.
We'll see about setting up Lazarus from SVN later (I've done that on
Windows, so I guess I'll be able to do that on Linux too).

I downloaded fpcbuild-2.2.2.tar.gz
I'll unpack it somewhere.

Since I do have a current working fpc 2.2.0, I guess it would not be a
good idea to "install" the new one in the same directory (if something
goes wrong, I might be left behind with no fpc at all)? My current fpc
source is in /usr/share/fpcsrc.

I guess I'll first have to do
make cycle PP=/path/to/current/fpc (in the fpcbuild-2.2.2 directory), then a
make clean all then a
make install INSTALL_PREFIX=/usr/local OPT='-gl'
to get a working fpc 2.2.2?

Does this sound like a good plan?

Hi Tom,

I didn't knew about this option under Keyboard settings, but that's exactly
what makes it hang - it doesn't crash, just hangs until you "use the Force"
Quit.

I applied the same settings for my Mac with 10.4.11, and this makes it hang
too - even with a small test program with nothing on it but a TButton.

I noticed in the Mantis a fix is targeted to 1.0, but could I (until then)
be able to work around this by capturing the key event for VK_TAB and make
the controls ignore this on certain forms? I could try...

Or maybe I could investigate a little bit more about this setting.

Normann

I think it is simillar to
http://mantis.freepascal.org/view.php?id=10054 . I don't have 10.5
version, but I think there is same option under Keyboard settings. I
have not found how to detect this settings so far. But it should not
certainly hang.

This is not managed by Lazarus. I think, you can control it via
Info.plist file in your app bundle, see

What is the question exactly ?  I understand it as:

"Would the lazarus community pay commercial developers to port their components 
?"

Am I correct ?

[Lazarus] Commercial components for Lazarus

Hello List,

I have written a post to the database section of the Lazarus forum about a 
commercial database engine recently ported for Lazarus, which made me think 
about the whole "Commercial components for Lazarus" issue. This is a part of 
that post: (It can be found here

This is asking for more trouble. Generally, don't add the path to lazarus 
sources in 
a -Fu option, instead use the appropriate directory with compiled units, in 
this 
case c:\lazarus\ideintf\units\i386-win32. Otherwise you may have two sets 
compiled 
units for the ideintf package and you get errors like checksum changed, etc.

Better yet, is to add a requirement of the IDEIntf package to the package or 
project 
you are trying to compile.

[Lazarus] Carbon: 10.4.11 tab key hangs on 10.5.4

[EarMaster - Bent Olsen]

Hi all,

I'm not sure if this was already brought up, and I did search bug tracker -
with no luck.

I've noticed that many native Mac OS X controls no longer receives focus in
10.5.4, which also can be seen in applications like Safari - you simply
can't tab through all controls on HTML pages and toolbars as you can in
10.4.x, and only edit boxes seem to get focus.

This affects applications compiled with 10.4.11 and trying to run on 10.5.4
- you can test this by placing a TButton on a empty form, compile it with
Lazarus on 10.4.11, and run the application on 10.5.4 - then hit tab key. It
simply hangs, because there is nothing on the form to receive focus anymore
- as there would in 10.4.11.

This test wouldn't crash if you placed a couple of edit boxes, which could
receive the focus - but the button no longer get focused, which it usually
did in 10.4.11.

I have FPC 2.2.2, Lazarus 0.9.27 r16996 on i386-darwin-carbon. I have no
FPC/Lazarus installed on 10.5.4, so I can test this the other way around.

We can workaround the focus issue, but not if it hangs every time the user
hits the tab key.

Has anyone come across this problem, and found a solution for it?

Best regards,
Normann

[Lazarus] Building Lazarus for win32

[tommy]

Hello, I have a problem with rebuilding lazarus when adding components. 
The componets are lazreport and ZEOSlib. Before this upgarde all worked 
fine. Now I get a stop when the rebuilding tries to recompile 
interfaces, with  a message that system checksum have changed, cant find 
the interface.pp. All searchpaths are correct in the cfg.
I have installed the new release of lazarus0.9.26 with fpc 2.2.2 and 
also tried the fixesbuilds with the same result.
The fresh install of lazarus functions as it should, but as soon I do a 
rebuild of lazarus it stops with the same message, and that even without 
adding och removing any componets from the packages. I also tried the 
comandline with --build-ide=

What am I missing? All paths are as by default, and I have the paths set 
in windows XP as before. lazarus.cfg contains all searchpaths to all 
files and units that lazbuild don´t find.

Can you try gdb, heaptrc and valgrind to get more information?

I don't know when I will update to intrepid, so I can't say when I will be able
