Desktop (please complete the following information):

• OS: Guix System (GNU/Linux)
• Latest commit of mygui-next (https://github.com/cryham/mygui-next)

[cryham]

This is looking like mygui-next didn't find ogre-next at all.
Are you building mygui-next on its own?
Or using my script to build all?
https://github.com/stuntrally/stuntrally3/blob/main/build-sr3-Linux.py
Are you sure you have got the ogre3 branch and have the same folder tree as I wrote there:
https://github.com/cryham/mygui-next/tree/ogre3
BTW. does the SR 3.2 Linux binary work on Guix?

[apteryks]

I was using the master branch; I'll retry using the ogre3 branch and keep you updated. I'm building mygui-next as its own package, not using the Python script, as this is how we try to package things in Guix (one package == one software, no bundled sources if possible, no network access during build, etc.).

I haven't tried the Linux binary yet; typically those do not work on Guix without setting up some kind of FHS (file hierarchy standard) container, which can be done with guix shell --emulate-fhs.

Thanks for your answer!

[apteryks]

OK, I'm now using the latest commit of the ogre3 branch, trying to build it against ogre-next 3.0.0, and this is what I now get:

Any ideas?

[cryham]

Well, MyGUI can't find Ogre file OgreHlmsUnlitDatablock.h. This one is needed.
I'd first check if it exist there, I got it here: ../Ogre/ogre-next/Components/Hlms/Unlit/include.
If it does, then it means path is missing or wrong? In your command it is this:
-I/tmp/guix-build-mygui-next-3.2.3-0.a1490ff.drv-0/Ogre/ogre-next/Components/Hlms/Unlit/include
I'd expect that file there and if so this command should build.

[apteryks]

Indeed. I'll check if I can make use of the FindOGRE.cmake more effictively to locate my system-provided Ogre-Next library.
