QT as a plugin for eclipse cdt doesn't work

Hello guys,

I have tried now about 8 hours to get running qt on eclipse. Also I have installed MinGW, QT Integration and CDT for C++ programming under eclipse.

I get following error messages on my console if I try to compile an empty project:
19:00:08 **** Build of project test ****

If I try to compile with the command line and g++ I get following error message:
main.cpp:1:18: fatal error: QtCore: No such file or directory
compilation terminated.

I hope this helps to find the error.

Check your main.cpp to ensure the syntax is correct for the QtCore entry. Seems it trying to read it as a file verse and include.
