Code::Blocks crashes during project reload

[alexchen]

I am using version 17.12 on CentOS 7.5  I encounter a crash when several project files, i.e. *.cbp, are modified externally via a editor and Code::Blocks offers to reload these projects.
This is the stack trace from the dump file:

==========
It seems to me that the ProjectManager object has been deleted when the call happens.
It would be nice to build Code::Blocks with '-g' flag in projection build so that the line numbers are included in the dump file to facilitate crash analysis. (It can co-exist with the optimization flag, e.g. -O3)

[BlueHazzard]

You can build codeblocks quite easy by yourself, with the benefit to have the latest code, because 17.12 is quite old and there were tons of bugfixes...

[oBFusCATed]

This particular one is fixed in trunk...

[alexchen]

I downloaded the source code from trunk and the README file still still says "This is the Code::Blocks IDE version 17.12'.  Is it the latest copy?
I encountered another crash today.  It seems like a different issue.
I use Code::Blocks within my build script for multiple workspaces to build a RPM.
Do not know if the crash is a problem in libwx_baseu-2.8 or Code::Blocks.

I downloaded the source code from trunk and the README file still still says "This is the Code::Blocks IDE version 17.12'.  Is it the latest copy?

Yes, it is the latest version. We've not made a release, so we've not changed the version number.

I encountered another crash today.  It seems like a different issue.

Is this with the new version? How have you built/installed it?

I use Code::Blocks within my build script for multiple workspaces to build a RPM.

What do you mean by this?

p.s. Please use code or quote tags when pasting long texts!

[alexchen]

I have not built the source code yet.  I am using the prebuilt one from the download site, therefore the crash is from the original build.
From the stack dump, the problem is either in Code::Blocks' use of wxGTK API or wxGTK's own issue. 
If it is an issue in wxGTK, which is pretty old, maybe the it is fixed in wxGTK3? My CentOS 7 has wxGTK (2.8.12) installed (via Code::Blocks' dependency) and wxGTK3 (3.0.2) available.

What I am trying to says is that my build script invokes Code::Blocks command line multiple times for various workspace during the build. 
The crash always happens in one of the last few invocations during the process, but not necessarily in the same workspace.
I do not know if the repeated process of bringing up Code::Blocks via command line has any bearing to the symptom.


I just tried to build from the source by running the bootstrap command via the instructions in BUILD and got the following errors:

The bug is in C::B. You need to install the wxgtk-devel package. I'm using wxgtk 2.8.12 on centos7 and it works fine...

Here is a discussion of a similar problem:
http://forums.codeblocks.org/index.php/topic,23072.msg157018.html#msg157018

[alexchen]

Is it a known bug if it is in C::B?  It is the same bug you fixed in the beginning of the history?

[oBFusCATed]

Probably it is the same bug. When you build the trunk version and you test it we will know for sure.

[alexchen]

It seems to be stable, at least I have not encountered a crash yet. 
However, it is a local build, not a RPM, therefore the execution path is different, /usr/local/bin v.s. /usr/bin.
Is there somewhere I can get an installable dev build RPM for CentOS 7?
It will be even better if you can release an official RPM from current code base.  Cord dump is difficult for end users unless them have the time and energy to trace down the issue and build from source.
 
Thanks for the help.

BTW, it would be nice to update the BUILD file to include the dependency of wxGTK-devel and gamin-devel in build steps.
It would not build without these two packages.

[oBFusCATed]

Is there somewhere I can get an installable dev build RPM for CentOS 7?

Yes, you can build yourself a package by first doing make dist and then rpmbuild -ta codeblocks*.tar.bz2. You have to setup rpmbuild first. Also you have to do make uninstall to make sure your /usr/local is cleaned before it isn't too late.

It rpmbuild fails. You can edit the .spec file and comment the ./bootstrap line and then do the rpmbuild -ba codeblocks.spec.

[alexchen]

I have built the RPM successfully. Thanks for the information.  I suggest we add the package dependency and the RPM build steps in the BUILD document for people who wants to build the RPM to be installed on multiple machines.
