Description Karl Krach 2011-10-12 12:51:35 UTC 
Creating a toolchain for ARM with the latest Qt library will install it's libraries and QMAKESPECs. Theses QMAKESPECs have the CXXFLAGS and the correct compiler, but don't address the pkg-config location.

If using pkg-config with qmake, it calls pkg-config from /usr/bin which causes wrong include dirs.


########## Example ##########

Write to your *.pro file:

	# see http://doc.trolltech.com/4.6/qmake-project-files.html#configuration-features
	CONFIG    += link_pkgconfig
	PKGCONFIG += fuse


If the wrong pkg-config is used, the include directory points to "-I/usr/include/fuse" - otherwise to a directory inside your toolchain.

I'm using buildroot 2011.08 with the CodeSoucery 2009q1 toolchain.

Of course the patch is not to solve the problem, but to show how the QMAKESPEC should look like.

Fixed in git (a028c31ed07) - Thanks.
