Version

2.3.0

Operating system type + version

Linux x86_64

Behavior

When building the dependencies for the latest release the following error occurs when building wxWidgets:

[ 98%] Building CXX object libs/media/CMakeFiles/media.dir/__/__/__/__/src/unix/mediactrl.cpp.o
In file included from /usr/include/gstreamer-1.0/gst/gstbin.h:27,
                 from /usr/include/gstreamer-1.0/gst/gst.h:35,
                 from PrusaSlicer-2.3.0/deps/build/dep_wxWidgets-prefix/src/dep_wxWidgets/src/unix/mediactrl.cpp:18:
/usr/include/gstreamer-1.0/gst/gstelement.h:55:10: fatal error: gst/gstconfig.h: No such file or directory
   55 | #include <gst/gstconfig.h>
      |          ^~~~~~~~~~~~~~~~~
compilation terminated.
libs/media/CMakeFiles/media.dir/build.make:110: recipe for target 'libs/media/CMakeFiles/media.dir/__/__/__/__/src/unix/mediactrl.cpp.o' failed

The gstconfig.h file is actually in /usr/lib64/include/gstreamer-1.0/gst. If it is copied/linked into /usr/include/gstreamer-1.0/gst then the build completes. The pkg-config file for my install of gstreamer-1.0 includes the correct include paths. Do the cmake files use this information? For instance on my system:

> pkg-config --cflags-only-I gstreamer-1.0        
-I/usr/include/gstreamer-1.0 -I/usr/lib64/gstreamer-1.0/include -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include

In googling this error, this is a common problem with the gstconfig.h file. The standard location is for it to be installed is under a 64-bit lib directory (eg: /usr/lib/x86_64-linux-gnu/gstreamer-1.0/include/gst, or in my case /usr/lib64/include/gstreamer-1.0/gst)

Many other packages a simple make clean/distclean causes the make process to re-evaluate the pkg-config paths and cleans up the error in the auto generated make files.

For now I've created a symlink and that allows the build to continue. I'll remove the link when 2.3.0 is finished.

No, this is an issue with your rollout of wxWidgets which the dependencies download from YOUR git server. This isn't static wxWidgets, this is a custom build that your team maintains.

I'm guessing this is mainly because the distribution I run (Slackware) does not do 32bit compatibility. It is strictly a x64 system and thus this include file is in a 64bit library location because it has 64bit requirements. There's probably a 32bit version of it as well.

You are not passing the correct CFLAGS to your cmake files that your project maintains.
