I tried to compile Openglad, a port of an old DOS game I believe, on my Mandrake 9.1 system. When I typed ./configure I got the following output.

I checked and I have SDL 1.2.5-5mdk installed, it was installed initially on the computer. I also tried installed SDL 1.2.6 from the SDL site, but immediatly got an error about it conflicting with SDL 1.2.5 so I gave up on upgrading SDL. I figured this verysion should work as it is newer than 1.2.0. Please Help...

Thanks,

You need to install the SDL-devel rpms - the ones you installed just contain runtime files, not development headers and libraries.
