Unable to compile on Mac for Debian

[brsnik]

I'm running MacOS on Intel and getting the following error when I try to compile with targets: aarch64-unknown-linux-gnu, i686-unknown-linux-gnu and x86_64-unknown-linux-gnu.

$ sudo cargo deb --target=x86_64-unknown-linux-gnu

Unfortunately, cargo is not smart like zig, and does not support cross-compilation of executables out of the box. You have to manually configure a C cross-linker and create and configure a sysroot with Linux's glibc and other C libraries. This is a general design issue with cargo build, not cargo deb.

This is very fiddly and annoying to do on macOS, so I suggest compiling Linux executables in Docker instead.

FYI I've been successfully using the cross tool for our projects for a few years now, and I roughly noted my reasons for doing so here.
