Hi all,

Qt installs pkg-config files on GNU/Linux systems, but apparently not on
other systems such as Mingw. Would it be possible to force installation
of the pkg-config files in Mingw-cross-env?

The required information seems to be already available in the
usr/i686-pc-mingw32/lib/Qt*.prl files, so maybe there's a simple switch
that forces installation of the pkg-config files?


Hi Martin,

Unfortunately, it's more complicated than setting a switch.

Qmake's unix makefile generator has the ability to write pkg-config files. However, the win32 generator is used for building Qt for Windows, including when cross-building on unix, and this generator does not make pkg-config files. See qmake/generators/ in the Qt source tree.

Arguably, the unix makefile generator should be used to generate makefiles when cross-building, but in practice the win32 makefile generator is a better fit and its makefiles intended for mingw32-make or msys-make work just fine with gmake on unix.

If you are so inclined, you might try porting the pkg-config writing feature to the win32 generator. It probably makes more sense than making the unix generator suitable for cross-building for mingw on unix.
