Use Meson 0.52, version 0.53 introduced this regression among others: https://github.com/mesonbuild/meson/issues/6431 DPDK CI also has Meson version pinned to 0.52, see http://mails.dpdk.org/archives/dev/2020-January/154357.html I find it handy to switch Meson versions via pip3. Here's Meson 0.52 output: > $ meson --cross-file meson_mingw.txt build/cross/mingw > The Meson build system > Version: 0.52.0 > Source dir: /home/dmitry/src/dpdk.clean > Build dir: /home/dmitry/src/dpdk.clean/build/cross/mingw > Build type: cross build > Program cat found: YES (/usr/bin/cat) > Project name: DPDK > Project version: 20.02.0-rc1 > C compiler for the build machine: cc (gcc 9.2.0 "cc (GCC) 9.2.0") > C linker for the build machine: GNU ld.bfd 2.33.1 > C compiler for the host machine: /usr/bin/x86_64-w64-mingw32-gcc (gcc 9.2.0 > "x86_64-w64-mingw32-gcc (GCC) 9.2.0") > C linker for the host machine: GNU ld.bfd 2.33.1 As you can see, it correctly picks up CC and LD for host machine, unlike 0.53. -- Dmitry Kozlyuk
