Can reproduce on EndeavourOS with KDE, build from the AUR with yay.

If you need more information/test feel free to ping me :)

[snsrkn]

I get the same error on Arch Linux. I try to build with Paru, but it fail.

[JoseExposito]

This seems to be a Meson issue:

  File "/usr/lib/python3.11/site-packages/mesonbuild/modules/gnome.py", line 972, in _make_gir_target
    cc_exelist = state.environment.coredata.compilers.host['c'].get_exelist()
                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^^^
KeyError: 'c'

subprojects/libtouche/meson.build:37:6: ERROR: Unhandled python exception

    This is a Meson bug and should be reported!

Looking at their code, the line that is crashing was introduced here: https://github.com/mesonbuild/meson/commit/bf44120a4f272652f98c607bd05065e8a0492d3a

And:

$ git tag --contains bf44120a4f272652f98c607bd05065e8a0492d3a
1.2.0
1.2.0rc1
1.2.0rc2
1.2.0rc3
1.2.1

I tested it and meson <= 1.1.1 works, but meson >= 1.2.0 fails, so I think that that is the culprit commit.

I opened a bug report in meson: https://github.com/mesonbuild/meson/issues/12162 As a workaround, you can use a working version of meson (pip3 install --user meson==1.1.1) to compile it.

[JoseExposito]

I added a workaround on my side to make the project build with any meson version.

I'm creating a new release that should fix the problems with AUR.

Here is the release: https://github.com/JoseExposito/touche/releases/tag/2.0.10
