I think your problem lies more along the lines of lacking linux/unix experience
than anything else, then.

Compiling a single file from a larger project is something that with depressing
frequency fails, because it will usually depend on other files (btw, your
error reporting skills are somewhat lackluster; If you'd given us the error
output, we could almost certainly have helped you).

I'd recommend starting your own project instead, where you know all the
intrinsic dependencies.

Spending an hour or three with gcc's and ld's documentation will prove useful
too, I guess (gcc is the compiler, ld is the linker; Most developers use the
compiler to call the linker as well, so when you know 'gcc' inside out you'll
be able to start building just about anything you want).

For larger projects, investing some time with the documentation of 'make'
will be well spent time.

Good luck.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
