On Linux systems, the includes in /usr/include often reference
the headers which come with the kernel, through two symlinks called
/usr/include/linux and /usr/include/asm.

If these kernel headers don't exist, the symlinks don't point to
them, or there's a permission problem for ordinary users, then
compiles will fail.

You can test to see whether the headers are correctly installed
like this:

  less /usr/include/linux/types.h

Did you see a file?  If not, find out why, possibly by reinstalling
the kernel source into /usr/src/linux and running gmake with the
target that regenerates the asm link in /usr/src/linux/includes.

If you do see the file, then tell us what happens when you try
compiling the attached program like this:

gcc -v -Wall -pedantic -o hello hello.c

I hope this helps.

Regards,

Mitch.
