Erro building m1n1

Hi,

great work with packaging all this together.

Unfortunately for me building m1n1 doesn't work, i am getting this:

ecking if the linker (/private/tmp/nix-build-aarch64-unknown-linux-gnu-stage-final-gcc-debug-11.2.0.drv-0/build/./gcc/collect-ld) is GNU ld... (cached) yes

Seems to work fine on my x86 machine.

It looks like you are trying to build on Darwin but there’s an issue somewhere in Nixpkgs with building the compiler. Is the x86 machine Darwin or Linux? I know it builds on x86 Linux and am 99% sure it builds on aarch64 Linux.

I don’t claim support for using Nix on Darwin to build any of this. But m1n1 can be built on Darwin upstream so it would be nice to fix this issue. I think it uses clang, and the issue here is with building a component of GCC, so maybe the derivation will have to be modified.

Thanks, will close this for the time being, and let see if i can nail down and improve the derivation for darwin. Best. Dejan.
