Actually, for building with Qt you need additional settings.

What I use for a 64-bit build (32-bit is similar, but different) with
Qt4 is:


export QTDIR=/opt/mxe/usr/i686-w64-mingw32.static/qt

The first export I showed above takes care of adding to PATH the
location of qmake.  So you only change into the top directory of your Qt
project, where there should be a .pro file (which is what qmake uses),
and then follow the instructions.

Again actual use (needs knowledge of Qt) is:

make -j4 release


make debug

depending on your target (debug or release, as per Qt concept).

The -j4 is unrelated, tells make to use parallel make, up to 4
processors (Qt doesn't inherit what MXE uses in its own make).
