I installed PHP on my system with the purpose to test php stuff locally. Among the php files was a script that (apparently) needed the gd-library. I downloaded the gd-library from Boutell.com and it had to be compiled (I downloaded the Windows version btw, because I am using this under Windows), so I searched for a C-compiler. According to the manual provided with gd, mingw32 is a good choice. BUT, what next? I tried 'gcc gd.c', but all it gives are errors (see attached file) about missing files. Please guide me through this yet unexplored part of programming (I only did a bit with turbo pascal, but that are simple programs).
