Upstream needs to merge a PR related to usage of termio which was removed in glibc 2.42. It doesn't seem to get merged very soon, so here's the patch:

There is no requirement for gcc13 anymore, also a lot of sed stuff the PKGBUILD did is not necessary anymore. Here's the PKGBUILD:

}

gcc13 and gcc13-libs was removed from core, so I needed to mangle the build a bit. I first tried regular build with current default gcc (version), but ran into incompatible pointer type errors, which could be circumvented by passing -Wno-error=incompatible-pointer-types, but due to a bug in src/gui/CmakeLists.txt this breaks the resulting make.flags.

If you're impatient, you can patch that CmakeLists.txt yourself with this fix-cmakelists-quoting.patch:

I've also heavily cleaned up the PKGBUILD, removing commented-out seds, removing single-thread building, and making use of this fix by passing along CMAKE_C_FLAGS and CMAKE_CXX_FLAGS to speficy -Wno-error=incompatible-pointer-types. Here's the complete PKGBUILD (patch file and command could be removed after upstream accepts previously linked PR):

  cd ../../TOWNSEMU/build_gui

}

This package seems to be broken due to some issue with cmake upstream. I filed: https://github.com/captainys/TOWNSEMU/issues/145

The error(s):

/bin/sh: line 1: -Wno-unused-variable: command not found
/bin/sh: line 1: -Wno-unused-variable: command not found
clang++/bin/sh: line 1: -Wno-unused-variable: command not found

I noticed I can't compile anymore since upgrading to GCC 14.x. As a workaround, you can compile with (latest, v19.x at this moment) clang, by exporting CC and CXX in the PKGBUILD. Juist add the following two lines to the build() function, at the beginning:

export CC=/usr/bin/clang
export CXX=/usr/bin/clang++

Now I can compile
