I am brushing up my C coding capability ... if any (???) I started up with a stand-alone simple program (see attachment) hich I compile through one simple command line. The compiler cannot resolve the include statement about elements that belong to glib, no matter how I reshuffle such statements (error messages pasted at the bottom of this message). Since an assistant professor and I installed the glib in such a way as to make the undocumented code, developed by a student who left some months ago, work somehow ... I am afraid we messed up the glib installation so that instead of having its pieces stored in the standard system files its pieces were spread elsewhere therefore the gcc compiler cannot find them. My question is: where is the glib expected to be installed by default (as gcc expects) ? How can I make up for the mess we did ? I mean, shall I un-install glib (how) and then reinstall it again following the standard pathway ?
