zig-cross

Example of using zig as a CMake Toolchain for cross compiling.

Reference: https://zig.news/kristoff/cross-compile-a-c-c-project-with-zig-3599

Building

  • Install zig in your PATH (choco install zig on Windows)
  • cmake -B build-aarch64 -G Ninja -DCMAKE_TOOLCHAIN_FILE=cmake/zig-toolchain-aarch64.cmake
  • cmake --build build-arch64

You can create toolchains for other triples like this. Here is an example to build for Windows on ARM64:

set(ZIG_TARGET "aarch64-windows-gnu")
include(${CMAKE_CURRENT_LIST_DIR}/zig-toolchain.cmake)
