code::blocks hangs at startup

[killerbot]

2 days ago, since a very long time, I did a fresh build of CB on linux, in Tumbleweed.
Build goes fine, but launching fails. With a similar problem as mentioned above, and the 'renaming' the 3 wxSmith zip files.
Probably when starting a build by excluding these plug-in(s) things would have been ok too.

Code

sudo mv /usr/local/share/codeblocks/wxSmithAui.zip /usr/local/share/codeblocks/wxSmithAui.old
sudo mv /usr/local/share/codeblocks/wxsmithcontribitems.zip /usr/local/share/codeblocks/wxsmithcontribitems.old
sudo mv /usr/local/share/codeblocks/wxsmith.zip /usr/local/share/codeblocks/wxsmith.old

Conclusion: this problem is not solved yet, did anyone in the meantime had a look at it ?



for reference, I stumbled also upon: https://bbs.archlinux.org/viewtopic.php?id=308575

What wxWidget version is being used?
My wild guess is the png images; I checked one image file and if not wxCHECK_VERSION(3, 1, 6) then png images are used.
Edit: The single source file (wxsitemeditor.cpp) I checked was the only one that used the svg images if 3.1.6 or newer.

Works OK on Ubuntu 22.04 with wxWidgets 3.2.6, I cannot check on other Linux. wxSmith uses some initialization tricks that may be non-portable.

This ticket reports that downgrading gdk-pixbuf2 from 2.44.2-1 to 2.42.12-2 fixes the problem.

[Miguel Gimenez]

On 2.43 gdk-pixbuf deprecated the XPM api and disabled XPM loader by default, see release notes.

wxSmith defines a XPM in wxSmith.cpp:50 and uses it during plugin attachment in wxSmith.cpp:211; Probably changing this XPM to a PNG or SVG fixes the issue.

[Miguel Gimenez]

Replaced XPM with PNG in OnAttach(), see r13773, this may fix the issue (untested).

There are more XPM bitmaps in other parts.

the wxwidgets I used is : 3.2.8

I updated with your latest commit, the problem is still there.

fyi: my gdk-pixbug version is 2.44.4

Can you put a breakpoint in OnAttach() and check where it hangs?
