I'm trying to install gtk-gnutella and I've hit a road bump.

the configuration went perfectly well and ended with the message "Now you must run '/usr/bin/make'."

I typed /usr/bin/make and just got a series of error messages ending with:
make[2]: *** [main.o] Error 1
make[2]: Leaving directory `/home/kkatebian/Software/gtk-gnutella-0.95.2/src'
make[1]: *** [subdirs] Error 1
make[1]: Leaving directory `/home/kkatebian/Software/gtk-gnutella-0.95.2'
make: *** [all] Error 2

I typed make and got the same

I did all this as root as well

Can someone help me?

What did it say in the 5-10 lines before that? It's a bit like a car crash. You've shown us the crash, we need to see what happened before that. Also, what options did you choose when you configured it?

I made a mistake in the first post as well, /usr/bin/make returned no such file or directory.
It was just make that returned the error.

so far as options are concerned, all the default settings were selected except gtk1 was used instead of gtk2.

as for the previous lines, they were all error lines, a few hundred or so.

here they are though:
main.c:492: error: `G_LOG_LEVEL_DEBUG' undeclared (first use in this function)
main.c:499: error: `FALSE' undeclared (first use in this function)
main.c:517: error: `saved_errno' undeclared (first use in this function)

core/matching.h:83: error: storage size of `all_entries' isn't known
core/nodes.h:112: error: storage size of `header' isn't known

it's basically what looks like a thousand lines of error, warning, error, warning, ...

Well go back to the start of the errors, where it starts to go wrong

here are the first few lines:

Well there it is,
glib.h: No such file or directory
It looks like you need to install the development version of glib-1.2

Not only was it already installed, I've re-installed it twice all the while I've been trying to install the program.

There's no way that it wasn't installed properly since I did it through the ubuntu package manager.
