I have downloaded qt-mingw and installed it. Mingw was downlioaded during installtion. then in installed qdevelop.

This resulted in the complainment of qdevelop not knowing where make, gdb and ctags are located. I set up make as he mingw-make.exe.

Now qdevelop starts compiling, but it ends with the error:
Erstellen (make)...
C:/MinGW/bin/mingw32-make.exe -f Makefile.Release
mingw32-make.exe[1]: Entering directory `C:/Dokumente und Einstellungen/Matthias/Eigene Dateien/DEv/Qt/examples/chap01/hello'
mingw32-make.exe[1]: Leaving directory `C:/Dokumente und Einstellungen/Matthias/Eigene Dateien/DEv/Qt/examples/chap01/hello'
Makefile.Release:58: *** missing separator. Stop.
C:\MinGW\bin\mingw32-make.exe: *** [release] Error 2
what is wrong ?

PS: Visual Studio is installed as well, but not used here.
