I have installed Qt 5.0 (the whole SDK) on Fedora 17. I have configured the compiler (GCC) and everything seems to be working fine, except that when I press "Ctrl-R" for having a demo of my GUI coding, I get the following error :
make: Entering directory `/home/Nisarg/Documents/Qt Projects/untitled-build-Desktop_Qt_5_0_1_GCC_32bit-Debug'

make: Leaving directory `/home/Nisarg/Documents/Qt Projects/untitled-build-Desktop_Qt_5_0_1_GCC_32bit-Debug'
collect2: error: ld returned 1 exit status
make: *** [untitled] Error 1
04:07:17: The process "/usr/bin/make" exited with code 2.
Error while building/deploying project untitled (kit: Desktop Qt 5.0.1 GCC 32bit)
When executing step 'Make'.
(The error above is that a file called -lGL is not found)
How do I go about solving this error ?
