I am having trouble compiling anythnig in C on a new machine that I have started from scratch.

PIII-500
Slackware 10.0

When I installed, I ONLY installed the kernel, required packages, and the kernel source.
I have put the following programming related packages on from the cd one by one:
(not necessarily in this order)
gcc-3
gcc-g++
gcc-obj
glib
glib2
glibc
libtool
binutils
m4
make

Am I missing something important?

I have tried compiling numerous programs that worked on other machines, but I have always just installed "all development packages"

I get an error (among others) that says:
configure: error: C preprocessor "/lib/cpp" fails sanity check

another error i get is:
/usr/include/bits/errno.h:25:26: linux/errno.h: no such file or dir
make[1]: *** [common.o] Error 1

I checked and errno.h is in /usr/include/ and /usr/include/bits/

Any help would be greatly appreciated :-)
Thank you

You're missing the kernel-headers package.

Thank you for the kernel-headers advise, it got me much further now.

But, now I get this error:

/usr/lib/gcc.........linux/bin/ld: cannot find -lz
collect2: ld returned 1 exit status

any ideas?
