| If you set up your environment as described in [[Build/Unstable Version|Build/Unstable Version]], you can compile this code with
| |
|
| |
| gcc hello.cpp -o hello -I/home/kde-devel/qt-unstable/include/Qt \
| |
| -I/home/kde-devel/qt-unstable/include/Qt-Core \
| |
| -I/home/kde-devel/qt-unstable/include -I/home/kde-devel/kde/include \
| |
| -L/home/kde-devel/kde/lib \
| |
| -L/home/kde-devel/qt-unstable/lib -lkdeui -lkdecore -ldl
| |
| and then run it with
| |
| ./hello
