Neither the suggested overlay's wxGTK nor 3.2.1 in the gentoo repository seem to satisfy the ebuild's search.

You do not have to change the selected wxwidgets to get this to merge. I do not know if it will be detrimental to keep on 3.2 so I leave it to 3.0. Only Cemu needs 3.2 but eselect does not help to make it find it.

Does the file /usr/lib64/wx/config/gtk3-unicode-3.2-gtk3 exist on your machine? Is it executable?

Also, please attach the full log.

[Tatsh]

What it should look like:

 $ ls -la /usr/lib64/wx/config/gtk3-unicode-3.2-gtk3
-rwxr-xr-x 1 root root 49106 Feb 11 22:46 /usr/lib64/wx/config/gtk3-unicode-3.2-gtk3

Try the following commands and attach the logs:

cmake --debug-find-pkg=wxWidgets --find-package -DNAME=wxWidgets 3.2 -DCOMPILER_ID=GNU -DLANGUAGE=CXX -DMODE=EXIST > cmake-debug.log
cmake --debug-find-pkg=wxWidgets --find-package -DNAME=wxWidgets -DCOMPILER_ID=GNU -DLANGUAGE=CXX -DMODE=EXIST > cmake-debug-no-version.log

cmake-debug-no-version.log

[Tatsh]

Are you using wxGTK from Gentoo or stefan? If the latter, switch to the Gentoo one as the overlay is no longer needed.

[kzdixon]

I get the same behavior on both; had originally tried the gentoo one and then tried the other one when it was initially suggested.
gentoo's wxGTK is installed currently.

[Tatsh]

Need to re-run those commands and attach output, this time saving stderr.

cmake --debug-find-pkg=wxWidgets --find-package -DNAME=wxWidgets 3.2 -DCOMPILER_ID=GNU -DLANGUAGE=CXX -DMODE=EXIST > cmake-debug.log 2>&1
cmake --debug-find-pkg=wxWidgets --find-package -DNAME=wxWidgets -DCOMPILER_ID=GNU -DLANGUAGE=CXX -DMODE=EXIST > cmake-debug-no-version.log 2>&1

Need you to do something a little more complicated:

1. cd /var/db/repos/tatsh/games-emulation/cemu (or where it is)
2. edit the ebuild so it has the same debug argument passed to CMake:

diff --git a/games-emulation/cemu/cemu-2.0_p20230218.ebuild b/games-emulation/cemu/cemu-2.0_p20230218.ebuild

 }

2. Run ebuild cemu-2.0_p20230218.ebuild manifest clean configure
3. Post the build log.
4. git checkout . to reset the repository.

Sorry for the delay, nearly forgot to do this when I had time.

[Tatsh]

Run eselect wxwidgets set gtk3-unicode-3.2-gtk3 and post the log again.

I do not know what to do next here. You have a fairly customised setup and I think something in the environment is incorrect but it would be pointless to take more stabs at it I think. I cannot reproduce this issue and I have 2 systems detecting wxWidgets 3.2 (Gentoo's ebuild) without an issue.

You should grab the Cemu source and try building without Portage and see what the results are.

I'm not sure if this is the same issue as his one, but it seems at least similar :
https://gist.github.com/520fa64ffb4f13afd097c9f860a7c904
My wxGTK version is :
x11-libs/wxGTK-3.2.2.1-r300:3.2-gtk3/3.2.2::stefantalpalaru

I'm not sure why I'm using this wxGTK version instead of the one in ::gentoo.
It seems to me it is also causing issue with other packages.

[ghost]

I finally replaced x11-libs/wxGTK-3.2.2.1-r300::stefantalpalaru by x11-libs/wxGTK-3.2.2.1::gentoo.
It fixed sci-eletronics/kicad-7.0.0-r1::gentoo but not games-emulator/cemu::tatsh-overlay.

Here's my current build failure logs :

No this is not the same problem. Your wxWidgets 3.2 is getting found and you are getting past the configure phase. The issue you have is being resolved shortly.

[Tatsh]

@kzdixon I think I may have found the issue. Please update and try building again. Make sure you see the line x11-libs/wxGTK:3.2-gtk3[opengl] in the ebuild.

You can check with qgrep 'x11-libs/wxGTK:3.2-gtk3[opengl]' cemu.

@Tatsh ok I see. Thanks a lot.

Yep, that did it.

[Tatsh]

Thanks for the report.
