how come i can compile some programs with no problems but others do, even the configure went through smoothly. also i compiled xine player a few days ago, after i had a fresh installation of FC2, it's not compiling any more? this has happened b4 but i don't recalled how i fixed it. is there a general cause for this kind of arbitary errors to occur? e.g. missing packages? in order to prevent that from happening i have installed all the software development package from the FC2 cd, i've installed all the gnome ones even i am only using KDE. i guess there must be general cause for this to happen, can someone suggest what might be the problems?
