I’m currently trying to compile wezterm for riscv64. I’m orienting on this patch for Arch Linux PKGBUILD. Similar to the arch patch I already added the dependecy on the patched ring. Checkout the current state here.
When I now run nix build -L .#pkgsCross.riscv64.wezterm, I get the following error:
wezterm-riscv64-unknown-linux-gnu> The following warnings were emitted during compilation:

Since I’m totally new to NixOS, I tried to fix this by adding zlib to nativeBuildInputs but that didn’t change anything. Further, adding zlib.dev seems to do nothing as well.
Also, the riscv64 zlib package seems to include this header:
# ls -la /nix/store/sd3mn8r5k37vrqk93jyxravdvxc9ng9n-zlib-riscv64-unknown-linux-gnu-1.3-dev/include
total 124

I currently have no real idea where this issue could come from since the AMD64 build goes through clean. Could someone point me in the right direction?
