LinuxQuestions.org - Configure problem while building rpm with krpmbuilder on SUSE 10.0 OSS

Hey people!

I am trying to build an rpm using krpmbuilder. The program seems to do its job when it comes to building the spec file, I have checked it against various other specs and I don't see any differences I could not explain by some good logic thinking. (Why is the name different :P) Anyhow, when I try to actually create the rpm, configure quits with the error that my "C compiler cannot create executables". I use gcc version 4.0.2 20050901. (got by 'gcc -v') Oddly enough, if I run ./configure in the directory itself, it finishes like it should do. So I am wondering what my mistake is.
Searching told me to look for glibc-devel, so in YaST I did a search but it was installed. I updated everything plus I installed all the other patches, same for gcc, still the error.

I'd be very thankful if anyone knows the answer and would be nice enough to share it with me ;-) Also, I'd like to know about manuals, how-to's, et cetera, about rpm creating, be it graphical like krpmbuilder, be it commandline.

Greets and thanks in advance!
Zsub.

-Edit-
Okay, third edit. Could the fact that gcc is not able to create executables have something to do with the fact that the source is gzipped? I guess not, since it should be writing to a temp dir, but hey, you never know :-) I also read a post in a mailinglist somewhere, saying that the symlinks to gcc could be incorrect. Reinstalling gcc solved the problem there. I updated all packages of gcc and the like - which ought to give the same effect on SUSE&YaST - but that won't work for me.

-Edit-
Sheesh, second edit already... krpmbuilder also won't build another source (gaim-1.5.0) exiting with the same error. "C compiler cannot create executables"

-Edit-
Might be useful to have the log...
