I was able to find the build[1] but having an issue: $ ./x86_64-linux-gcc -v ./x86_64-linux-gcc: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.35' not found (required by ./x86_64-linux-gcc) ./x86_64-linux-gcc: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by ./x86_64-linux-gcc) ./x86_64-linux-gcc: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.33' not found (required by ./x86_64-linux-gcc) ./x86_64-linux-gcc: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.36' not found (required by ./x86_64-linux-gcc) ./x86_64-linux-gcc: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by ./x86_64-linux-gcc) With older GCC versions from your page I don't have this problem. I'm using Debian 10 still so so is my libc too old? ii libc6:amd64 2.28-10+deb10u2:amd6 GNU C Library: Shared libraries [1] https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/13.1.0/x86_64-gcc-13.1.0-nolibc-x86_64-linux.tar.gz -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
