Hi,

I have a problem compiling my first "Hello World" program with qmake. I am using QT 3.3.4 with Debian Sarge and gcc 3.3.5. I first compiled the Qt-Tutorial 1 from the Trolltech website by directly calling gcc without any problems:

Qt Code: 
  1. gcc -o qt1 main.cpp -I$QTDIR/include -L$QTDIR/lib -lqt-mt
To copy to clipboard, switch view to plain text mode 

Next I wanted to follow the direction from the tutorial and use qmake:

Qt Code: 
  1. qmake -project
  2. qmake
  3. make
To copy to clipboard, switch view to plain text mode 

The last call to make gave me a long list of errors:
Qt Code: 
  1. g++  -o qt main.o    -L/usr/X11R6/lib -lXext -lX11 -lm
  2. main.o(.text+0x30): In function `main':
  3. : undefined reference to `QApplication::QApplication[in-charge](int&, char**)'
  4. main.o(.text+0x41): In function `main':

What makes me suspicious is the first line containing a call to gcc, using X11 libraries and not Qt libraries...
