Ouch! I mean, I know what most of it is saying, but, it doesn't make a whole lot of sense to me since many of those .h files (except for stdio.h) are in the same dir as the .c files.
Umm...I got those libs and made a link to them in /usr/include but discovered in the process that part of my problem is that the C standard libs, which I've downloaded, are not linked into /usr/include. So I tried to link them and every time I try to my file browser crashes. Hmm...there's got to be a way...
Haha! Got it! The folder containing the standard libs had some big, long, ugly name. I renamed it Standard_libs and it linked in /usr/include just fine! That should solve most of my problems!
