Hi, Ralf.

I thought I'd try out your instructions on Fedora Core 3. I got someway
down the line, but compilation of qmake is failing because I haven't told
the compiler where to find the w32api headers:

    $ cd qt3
    $ export QTDIR=$PWD
    $ export QMAKESPEC=win32-g++
    $ export PATH=$PWD/bin:$PATH
    $ make -f Makefile.cvs
    $ ./configure -no-cups -platform win32-g++ -shared

g++ -c -O2 -fno-exceptions -fno-rtti  -DUNICODE -DQT_NO_TEXTCODEC
-DQT_NO_UNICODETABLES -DQT_LITE_COMPONENT -DQT_NODLL -DQT_NO_STL
-DQT_NO_COMPRESS -DHAVE_QCONFIG_CPP -I"." -I"generators"
-I"generators/unix" -I"generators/win32" -I"generators/mac" -I"../include"
-I"../include/private" -I"../include/qmake"
-I"/include"-I"/home/angus/mingw-xcompile/qt3/mkspecs/win32-g++" -o
tmp/qdatetime.o ../src/tools/qdatetime.cpp

gmake: *** [tmp/qdatetime.o] Error 1
qmake failed to build. Aborting.

I attach a detailed log of all I have done so far, but basically the MinGW
runtime and w32api are installed as
    /usr/local/i386-mingw32/
        bin/
        include/
        lib/

where do I input this infor?

One further, dumm question: qmake is being built with g++, not
i386-mingw32-g++ . That's correct, isn't it (because qmake will be used to
build the sources).

Angus
