Compile problem in vmalloc.h

Compile problem in vmalloc.h

[Erik Jansson]

Hi all!

I've looked and asked around for a while about this, but I can't seem to
find the answer. Maybe you know what's up.

I'm compiling a driver that's not part of the kernel tree (but it's GPL
anyway). It compiles nicely against the 2.4.8 kernel tree, but fails
with both 2.4.10 and 2.4.14. Those are the only ones that I've tried
though.

I'm using clean sources (nothing patched, make mrproper; make clean;
make config; make bzImage etc).

I'm using gcc version 2.95.4 20010902 (Debian prerelease).

The error I get looks like this:

gcc -c -o ./src/proc.o ./src/proc.c -D__KERNEL__ -DMODULE -O2 -Wall
-Wstrict-pro

Try adding this:

#include <linux/module.h>

to your driver, of course before the '#include <linux/vmalloc.h>' line 8)
