I get the same error as @VadeveSi below, also if I build it inside a chroot. How can I fix that?

To have full python support, the following needs to be added to compile option:

    -DCLINGO_BUILD_WITH_PYTHON=ON \

note that the package already depends on python and also has -DCLINGO_REQUIRE_PYTHON=ON

@VadeveSi The build succeeds in a clean chroot. Are you using a clean chroot?

Hi, I get an error when trying to install. I am using Lua 5.3.5 Thanks in advance.

Yes, works now.

@ewirch Fixed. Does this work for you now?

You changed CXXFLAGS only for the cmake invocation. It will be the original CXXFLAGS when ninja (and clang+++) runs.

@ewirch Fixed by modifying CXXFLAGS to remove -fvar-tracking-assignments during build().

Building this package fails, if debug option is enabled in /etc/makepkg.conf. This is because /etc/makepkg.conf adds a GCC specific flag to CXXFLAGS:

DEBUG_CXXFLAGS="-g -fvar-tracking-assignments"

Add !buildflags to PKGBUILD options to prevent makepkg of setting default CXXFLAGS.
