Hi all, I'm having trouble compiling any QT programs:

vapebait@chronos VapeCalc $ g++ -o VapeCalc main.cpp -lqt-mt
main.cpp:1:26: qapplication.h: No such file or directory
main.cpp:2:21: qwidget.h: No such file or directory
main.cpp:5: syntax error before `{' token
main.cpp:11: invalid use of undefined type `class MyMainWindow'
main.cpp:4: forward declaration of `class MyMainWindow'
main.cpp: In constructor `MyMainWindow::MyMainWindow()':
main.cpp:12: `setMinimumSize' undeclared (first use this function)
main.cpp:12: (Each undeclared identifier is reported only once for each
function it appears in.)
main.cpp:13: `setMaximumSize' undeclared (first use this function)
main.cpp: At global scope:
main.cpp:17: `main' must return `int'
main.cpp: In function `int main(...)':
main.cpp:18: `QApplication' undeclared (first use this function)
main.cpp:18: syntax error before `(' token
main.cpp:19: aggregate `MyMainWindow w' has incomplete type and cannot be
defined
main.cpp:20: `a' undeclared (first use this function)


If i use the full path in my #includes i get this:

vapebait@chronos VapeCalc $ g++ -o VapeCalc main.cpp -lqt
In file included from /usr/qt/3/include/qobjectdefs.h:42,
from /usr/qt/3/include/qwindowdefs.h:43,
from /usr/qt/3/include/qwidget.h:42,
from /usr/qt/3/include/qdesktopwidget.h:40,
from /usr/qt/3/include/qapplication.h:42,
from main.cpp:1:
/usr/qt/3/include/qglobal.h:714:21: qconfig.h: No such file or directory
/usr/qt/3/include/qglobal.h:777:23: qfeatures.h: No such file or directory
main.cpp:17: `main' must return `int'

The path to QT is /usr/qt/3/

Any help appreciated.

Thanks, Vapebait

So where is qconfig.h?

Did you install the QT header files there manually, or is that where an installer chose to put it?

Rather than supplying the full paths in
the source or header you should be
telling the compiler where to look :}
