Hello, folks, I like to program in Pascal for so many years, dating back to th e Pascal/MT+, and greatly appreciate the FPC and Lazarus.

Now I have a problem in using Lazarus on an user account in Mac OS X 10.4.11 ( Japanese). If I log-in on the administrator account, Lazarus and applications built by Lazarus work well. But if I use daily user account, Lazarus itself and Lazarus-made applications make an error at opening the file dialog. For e xample on the IDE, clicking the right button at the lazarus directory entry (a t Enviromnent -> Options) arises a floating point exception and IDE goes to di e. I guess it may do something with perivilege system but cannot troubleshoot further. Would you like to tell me any idea to solve the problem ?

. Would you like to tell me any idea to solve the problem?

Please report the bug to the manits: bugs.freepascal.org

It would be of a great help if you create a backtrace, so we can find what's actually causing the bug. Please read this page, to learn about creating a bug trace:

I tried Lazarus 0.9.26 for Mac OS X PPC, and recent snapshots (lazarus-0.9.26 .1.18700-20090216-powerpc-macosx.dmg and lazarus-0.9.27.18700-20090216-powerpc -macosx.dmg), in vain.

Thank you for kind advise. Unfortunately I had been under the digest mode, so that I have noticed your post (and my re-post X-( ) just now.

After posting, I have tried further installations onto other Mac's (all run un der 10.4.11). The results were :
1. iBook G4 12inch - NG
2. iBook G4 14inch - NG
3. QuickSilver G4 - OK
4. iMac G5 - OK

The most apparent difference between the NG / OK machines was the maximum scre en size. In the NG group, it was 1024x768. In the OK group, it was bigger. An d I found a work-around for this problem: to change colour-depth from 32bit(1 6M-colour) to 32K-colour mode, though some unstable actions still remain.

I will try the back-tracer you have mentioned and post the result.

Thank you.

Dmitry,

I wrote a small test program named 'project1' in Lazarus. Essentially, the pro
gram contains only three lines as following;
procedure TForm1.FormCreate(Sender: TObject);
begin
  OpenDialog1.execute
end;

Under 32K-colour mode, the gdb said:

(gdb) run
Starting program: /Users/blackcat/Documents/FPCtest/LazTest/project1.app/Conte nts/MacOS/project1
Reading symbols for shared libraries ......................................... .......................... done

Reading symbols for shared libraries . done
NavDialogCallback Error: NavCustomControl FilterIndex failed with result -5698 Reading symbols for shared libraries ....... done
Reading symbols for shared libraries .... done
Reading symbols for shared libraries .. done

Under errorous 16M-colour mode, I got:

(gdb) run
Starting program: /Users/blackcat/Documents/FPCtest/LazTest/project1.app/Conte nts/MacOS/project1
TCarbonWidgetSet.GetSystemMetrics TODO 50
TCarbonWidgetSet.GetSystemMetrics TODO 49
NavDialogCallback Error: NavCustomControl FilterIndex failed with result -5698

Program received signal EXC_ARITHMETIC, Arithmetic exception. 0x9f761c00 in approximateCube ()

These results help you?

Sincerely,
Haruo

Sorry, I forgot to get the back-trace. Since it has more than 60 lines, I wil l attach it. It works in this ML?

Haruo.

i don't have ppc mac available, intel-only.
I cannot reproduce the error here, but have made a guess fix. Please update from svn, and test if it helps.

Dmitry, Thanks for rapid fix. But I am not accustomed to building Lazarus as a n application bundle (I used to get pre-built binaries from the snapshots). P lease allow me a few days of trial.

Haruo

Dmitry, Bad news.
SVN 18769 Lazarus makes the same fault. The backtrace is attached.

Haruo.

More tests are required. I've anwered to you in the private email.

Thanks,
Dmitry

Thanks, I have sent the result in another (private) mail.

Haruo.
