Code::Blocks SVN version 2481 crashes often

[Jorg]

Hi all,

After I managed to get Code::Blocks running (wxGTK2.6.3 / Suse 10.0), I am experiencing random close downs of the application. I did a full checkout and rebuild, everything seems to be working fine, but at some points it simply dies on me.. I get messages like:

Compiling: ../../parserfm.cpp
codeblocks: cairo-ft-font.c:677: _cairo_ft_unscaled_font_set_scale: Assertion `error == 0' failed.
./cb.sh: line 3: 24881 Aborted                 ~/bin/cb/bin/codeblocks

It died while it was doing a compile step. I am not sure if the assetion error has anything to do with it, but as you can see the script that ran code::blocks suddenly aborts. It happened on a lot of occasions.

Can anyone shine some light on solving this? I am finally able to build code::blocks from source, but this as it is now is not usable as it leads to loss in my sources all the time.

Regards,

We 'd need the debugger's backtrace for the crash, to see what's going on.
Copy the script devel/run.sh to devel/debug.sh. Then edit devel/debug.sh and change the last line to read like this:
gdb --args $APP_DIR/codeblocks $@

Then run C::B from a console using devel/debug.sh. When it crashes, return to the console and type bt full. That's what's needed

I thought about compiling code::blocks in debug mode as well. However, I tried to recompile C::B again and failed because of some libs. I wanted to throw away a build dir but accidentally threw away all my builds + wxWidgets build. I will try to rebuild next week and also compile C::B as debug, this is what I do, maybe there is something is wrong in the build steps??

build wxWidgets like;
../configure --enable-shared --prefix=/home/jorg/related/src/wxGTK-codeblocks --enable-unicode
make;make install

then set the wx-config to point to the /home/jorg/related/src/wxGTK-codeblocks/bin/wx-config dir

build code::blocks like
./bootstrap
./configure --prefix=/home/jorg/bin/codeblocks
make;make install

Then I have to manually point the libs to the exec, which I run from the bin directory. ps. I removed the shellscript line as it was in the orignal text. Thanks for letting me know that was not allowed ;-)

export LD_LIBRARY_PATH=/home/jorg/related/src/wxGTK-2.6.3-unicode-shared-release/lib/
~/bin/cb/bin/codeblocks

This seems to work allright (the LD_LIBRARY_PATH is needed else a different version of wxWidgets is used), but the frequent abrupt closes is what I am facing now. I did not know about the output/run script, is it much different then using my own bash shell script?

I will try to rebuild code-blocks with debug, is --enable-debug enough in the build process? Should i use latest SVN or a different one, because all latest nightly build messages do not show me a linux source I can use, so I assume SVN is stable enough (version 2481)

No need to. Default build contains enough debug symbols to work with

You 'd use this script if you had built C::B using itself (with te project file). So since you 're using autotools, forget what I said.

Turn this to:

export LD_LIBRARY_PATH=/home/jorg/related/src/wxGTK-2.6.3-unicode-shared-release/lib/
gdb --args ~/bin/cb/bin/codeblocks $@


It's the same thing as I told you above.
Note that when you run this script, it 'll drop you inside gdb. To actually start C::B, type "run" (no quotes).

Thanks, I will look in it later this week. we have a couple of days off by thursday, so at least I can spend some time behind my PC again ;-)
