[Sloved] Network without gui

[jd]

Hello,

I have a problem to run my server application, because my application requires a x server. I will not compile with QtGui. Wich library i have included that requieres QtGui ?

Compiler message:
make
make -f Makefile.Debug

Add QT-=gui to your project file.

It works fine.

Thanks
