Arch Linux User Repository

You shouldn't require specifying GCC as the compiler, lest compiler flag errors arise (such as when Clang users specify -stdlib=libc++, which obviously isn't supported by GCC).

Here's a diff that fixes that:

why it is using '/home/erik/.local/bin/ninja' instead of /usr/bin/ninja` ?

ninja-1.11.1-3 is installed - if it needs some other form of "ninja," I don't know what it is.

When upgrading from 24.01 to 24.02 the build process with cmake can fail if you have cuda installed. It tries to use the cuda gcc and fails.

My work around was uninstalling cuda, updating, and reinstalling cuda.
