Lazarus freezes when start

[Petr Hlozek]

Lazarus won't run when you try to open it.

I tried to run it from gdb and got this:

The last line is very important. My program is creatd in Lazarus as well and I have the same prblem. Program freezes when start with the same error!

Thank you for taking the time to report this bug and helping to make
Ubuntu better.

> TLazarusManager.Run starting /usr/lib/lazarus/0.9.30/lazarus ...

As you are using Ubuntu Precise (12.04) I assume (you could run
"apport-collect 919832" to verify) that you are using lazarus 0.9.30.2
so this path seems wrong.

> PrimaryConfigPath="/home/ok2cqr/.lazarus"

I believe it is configured in the directory above. As a test I propose
you move that directory aside and see if lazarus can start. If yes, move
the directory in place again and find references to 0.9.30 and replace
them with 0.9.30.2

Please report back.

Paul

[Petr Hlozek (ok2cqr)]

Hello Paul,

the config path is correct. It is into my homedirectory. If i try

apport-collect 919832
Package lazarus not installed and no hook available, ignoring

I tried to remove the .lazarus directory but the problem is still the same. What is much worse, the same problem has my app compiled in Lazarus. It uses threads as well. It seems that the problem is somewhere in fpc or Lazarus itself.

I attached a screenshot where you can see how it looks like.

Looking at the screenshot it looks like you have mixing of versions. You
need the latest lazarus in Ubuntu Precise which is version 0.9.30.2-1
and NOT as the top of you screen shot shows 0.9.30-3. If I am correct,
version 0.9.30-3 was build against the previous version of fpc in
Ubuntu, so it will not work with the latest fpc.

Please install the "lazarus" package and run "apport-collect 919832"
again. I would really like to see the information that that would
provide, as it will tell us which versions of different dependencies are.

apport information

[Petr Hlozek (ok2cqr)]

The same problem after instalation lazarus package. I created simple app with a button that will start thread. After I defined UseCThread variable, program freezes when start.

[Paul Gevers (paul-climbing)]

> + Package: lazarus 0.9.30.2-1

Does the window header still say 0.9.30-3 as in the screen shot?

Please run the following commands and report the output:
update-alternatives --display lazarus
update-alternatives --display lazarus-ide
cat /etc/lazarus/environmentoptions.xml
ls -ald /etc/lazarus*

Paul

[Petr Hlozek (ok2cqr)]

Yes, there is still 0.9.30-3 in the title of the Lazarus window.

Please run the following line and choose the 0.9.30.2 option
sudo update-alternatives --config lazarus

If this fixes your problem I will file a bug in the Debian bug tracker
to improve the choice of the alternative, which I believe will probably
prevent this problem in the future. So please let us know.

Paul

[Petr Hlozek (ok2cqr)]

I choose 0.9.30.2 option and the same problem.

It seems more related to freepascal than to Lazarus. I'll try to install new fpc into Ubuntu 12.04, compile Lazarus and let you knwo if it helped.

[Petr Hlozek (ok2cqr)]

I just downloaded fpc 2.6.0 from sourceforge, compile lazarus in it and still the same problem :-(.

Status changed to 'Confirmed' because the bug affects multiple users.

[Patrick Chevalley (pch)]

This as been fixed upstream. Reason is thread management change in glib2 2.31.
See http://bugs.freepascal.org/view.php?id=21129

The fix is available here:
http://svn.freepascal.org/cgi-bin/viewvc.cgi?view=rev&root=lazarus&revision=35051

It apply without problem to Lazarus 0.9.30.2 source and for me this fix the problem.

[Petr Hlozek (ok2cqr)]

Hello,

please apply this patch. Author is Zeljan Rikalo. Thank you!

It will fix the bug caused by changes in threads in new glib library version.
