This has been tested by doing a cross-compile for armv8-a type using the linaro gcc toolchain. meson arm-build --cross-file aarch64_cross.txt ninja -C arm-build where aarch64_cross.txt contained the following [binaries] c = 'aarch64-linux-gnu-gcc' cpp = 'aarch64-linux-gnu-cpp' ar = 'aarch64-linux-gnu-ar' [host_machine] system = 'linux' cpu_family = 'aarch64' cpu = 'armv8-a' endian = 'little' It is hoped that those working on arm architecture can use this as a baseline to add arm support - both native compiled and cross-compiled - to the meson build.
