Currently we incorrectly think that posix_memalign() exists on Windows. This is because of a combination of:* the msys2/mingw toolchain/libc claim to have a __builtin_posix_memalign when there isn't a builtin of that name * meson will assume that if you have a __builtin_foo that counts for has_function('foo') Specifying a specific include file via prefix: causes meson to not treat builtins as sufficient and actually look for the function itself; see this meson pull request which added that as the official way to get the right answer: https://github.com/mesonbuild/meson/pull/1150
Interesting, TIL. Reviewed-by: Philippe Mathieu-Daudé <[email protected]>
Currently this misdectection doesn't cause problems because we only use CONFIG_POSIX_MEMALIGN in oslib-posix.c; however that will change in a following commit.
