/lib/cpp fails sanity check error message
 

I am trying to compile programs dealing with my DVD player on my notebook (libdvdcss, libdvdread, gxine) but when I try to compile them I ge the message:

configure:error: C preprocessor "lib'cpp" fails sanity check

I am runnign redhat 7.3 and have gcc 2.96 compiler. What does this error mean and what do I have to do?

Get cpp. Cpp is different from gcc.

I have CPP installed according to the rpm program. I have to wonder if there is som eother problem or should I just force a reinstallation?

It could also mean you have the wrong version. It's a good idead to used the same version that was used on your kernel. Do a cat /proc/version to find out which version was used to compile your kernel. See if that matches up to your installed version. If not, get that version.
