Arch Linux User Repository

I was able to build it using GCC 8 (gcc8 AUR package) using this diff to the PKGBUILD. It will probably work with gcc10, but I already had 8 installed.

This isn't building now, it's giving an error when configuring binutils:

"checking whether the C compiler (gcc -Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now ) works... no configure: error: installation or configuration problem: C compiler cannot create executables."

This may be an issue with current compilers on Arch, or an issue with just my system, as I have the same issues building from source using the default flags, as well as with using clang.
