Cross-compilation under macOS
For Linux
First, install the following tap:
$ brew tap messense/macos-cross-toolchains
Then, install the toolchain for the desired Linux target:
$ brew install x86_64-unknown-linux-gnu
Then, set the environment variables for your shell (here Fish, use export
for Bash or Zsh):
set -x CC_x86_64_unknown_linux_gnu "x86_64-unknown-linux-gnu-gcc"
set -x CXX_x86_64_unknown_linux_gnu "x86_64-unknown-linux-gnu-g++"
set -x AR_x86_64_unknown_linux_gnu "x86_64-unknown-linux-gnu-ar"
set -x CARGO_TARGET_X86_64_UNKNOWN_LINUX_GNU_LINKER "x86_64-unknown-linux-gnu-gcc"
Warning : the fact that the Cargo environment variable is all in capital letters is important.
For Windows
$ brew install mingw-w64
