From 8596b3bcd12371ad16e5ffbd3e34953603cd1484 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Thu, 22 Jul 2021 12:01:01 +0200 Subject: interpreter: detect and pass compiler to be used for linker tests Allow using the links method to test that the C++ driver (e.g. g++) can be used to link C objects. One usecase is that the C compiler's libsanitizer might not be compatible with the one included by the C++ driver. This is theoretically backwards-incompatible, but it should be treated as a bugfix in my opinion. There is no way in Meson to compile a .c file with the C++ driver as part of a build target, therefore there would be no reason to do something like meson.get_compiler(meson.get_compiler('cpp').links(files('main.c')).
