Hi Robin,

I looked at your PKGBUILDs. In general, they look very good! I have a few questions:

Regarding clipboard and clipboard-git:

Doesn't setting CMAKE_C_FLAGS or CMAKE_CXX_FLAGS make it ignore the CFLAGS and CXXFLAGS in the environment?

Regarding unrar-free:

Doesn't passing CFLAGS to configure make it ignore the CFLAGS in the environment?

Regarding ame and ame-git:

You export 'RUSTUP_TOOLCHAIN=nightly'. Does Amethyst require nightly Rust to build?

If it doesn't, it would break building on systems using rustup but only the stable toolchain installed.

If it does, I think you should makedepend on rustup and ensure the nightly toolchain is installed in prepare(). This would also allow it to build in clean chroots.

Regarding malachite:

You export 'RUSTUP_TOOLCHAIN=stable'. I think you should just let it use the default toolchain because the stable toolchain might not be installed and using a newer toolchain shouldn't break the build. (In general, I would expect the stable toolchain to be the default, to match the rust package.)

Greetings,

Jan
