LinuxQuestions.org - Problems installing glib and gtk+ 1.2.10...

I am having some problems installing glib and gtk 1.2.10. After what seemed to be a successful install of glib 1.2.10 on my newly installed SuSE 8.0 machine, I tried ./configure on GTK 1.2.10, but it gives me an error message about needing X libraries. What libraries does this refer to? Is there a file to download full of many X functions? If so what is the name? Check out my console output...

I could post the config.log file, but I figured that wouldn't be necessary unless you needed to see it. Anyway, you guys are awesome and this forum is great. I have been on/off trying to switch over to Linux permanently but something is always holding me back. Maybe this time I will stay.

PS - Could someone please explain to me the purpose of a SOURCE RPM? Is it not a precompiled binary? And if so, shouldn't any SRC.RPM work on any RPM system since it is source code?
