I am not completely sure that programs built with MinGW-w64/MSYS2 are indeed
independent of an installation of this platform. At least they are not for a
default build. I checked this with one of the C examples: it requires
LIBWINPTHREAD-1.DLL and LIBSHP-1.DLL (it seems to be from the Shapelib library,
so not a system DLL) to be present in the path (of course you can include these
in the PLplot distribution).
It might be a good idea to find out if the reference to LIBWINPTHREAD-1.DLL can
be eliminated via a static version of that library. Then I think the program
will be entirely independent of the MinGW-w64 installation. A first glance at
the available static libraries indicates that this is not impossible. It will
be a matter of finding the right compile/link switches.
Apart from this: I agree that the MinGW/MSYS platform is not to be recommended,
if only because of the severe lack of package management.
Regards,
Arjen
