Cross Compilation from macOS to Linux fails

[franziskusz]

Edit:

My bad, the build command was wrong:
CARGO_TARGET_X86_64_UNKNOWN_LINUX_MUSL_LINKER=x86_64-linux-musl-gcc cargo build --release --target=x86_64-unknown-linux-musl

and

CARGO_TARGET_AARCH64_UNKNOWN_LINUX_MUSL_LINKER=aarch64-linux-musl-gcc cargo build --release --target=aarch64-unknown-linux-musl

worked as expected.

error: linker `x86_64-unknown-linux-musl-gcc` not found | = note: No such file or directory (os error 2)
and
error: linker `aarch64-unknown-linux-musl-gcc` not found | = note: No such file or directory (os error 2)

even though both are installed:

which aarch64-linux-musl-gcc->
/usr/local/bin/aarch64-linux-musl-gcc

which x86_64-linux-musl-gcc->
/usr/local/bin/x86_64-linux-musl-gcc

What was the corrected command?

The ones in the build-commands.txt should work in combination with this cargo config. And you also have to install the respective rust toolchain + c-linker like in this example before.

But I still am working on testing the builds: #2
