graphene @ meson.build:162:2: ERROR: Problem encountered: No aligned malloc function could be found.

[Cor0n4V1rus]

build fails, but works, if I run

port install graphene configure.compiler=macports-clang-7.0

after comparing the two main.log files, I noticed that, with clang-7, the configure process finds the function posix_memalign, while clang-9 does not and therefore does not proceed.

mmm. I thought I had fixed this once and for all. Will recheck what's going wrong...

[kencu (Ken)]

works for me with macports-clang-9.0...

I am admittedly using my current hot-rod new linker ld64-409, but that appears irrelevant...

I can't explain how it worked for Ken. It's a bug in meson. It will affect any project using meson's has_function and clang 8 or later. I've reported it here: ​https://github.com/mesonbuild/meson/issues/7204
