pkg-config(1) on OpenBSD is not the one from freedesktop.org and hence has
subtle differences (which don't impact real usage). The meson test fails
because white space between operators are stripped by our pkg-config:
$ grep Require /usr/local/lib/pkgconfig/xmlsec1.pc
Requires: libxml-2.0 >= 2.8.0 libxslt >= 1.0.20
$ pkg-config --print-requires xmlsec1
libxml-2.0>=2.8.0
libxslt>=1.0.20
There actually is an ICC for windows that can be used to cross compile
from Windows to Linux, but it's not supported in meson currently and I
don't plan to enable it.
This test currently assumes that the fortran compiler is gfotran, and
if we're not using g++ it skips. This patch changes it to skip if the
fotran compiler and the c++ compiler aren't the same family. This still
may skip in some cases it shouldn't (clang and gfort probably work fine
on windows), but it does enable ifort + ICL. Which is hte point.
Currently C++ inherits C, which can lead to diamond problems. By pulling
the code out into a standalone mixin class that the C, C++, ObjC, and
Objc++ compilers can inherit and override as necessary we remove one
source of diamonding. I've chosen to split this out into it's own file
as the CLikeCompiler class is over 1000 lines by itself. This also
breaks the VisualStudio derived classes inheriting from each other, to
avoid the same C -> CPP inheritance problems. This is all one giant
patch because there just isn't a clean way to separate this.
I've done the same for Fortran since it effectively inherits the
CCompiler (I say effectively because was it actually did was gross
beyond explanation), it's probably not correct, but it seems to work for
now. There really is a lot of layering violation going on in the
Compilers, and a really good scrubbing would do this code a lot of good.
