Hello,
I've been trying to implement the hello world code from the device
drivers chapter of "Beginning Linux Programming". I'm trying to create
a module that I can test with the insmod command. I keep getting errors
because I'm compiling using the wrong header:
In file included from /usr/include/linux/module.h:10,
from hellokernel.c:3:
/usr/include/linux/config.h:5:2: #error Incorrectly using glibc headers
for a kernel module
However, I've invoked the compiler as follows:
gcc -D__KERNEL__ -isystem/lib/modules/2.6.9-1.667/build/include/linux -
DMODULE -Wall -O2 -c -o hellokernel.o hellokernel.c
And I tried:
gcc -D__KERNEL__ -I/lib/modules/2.6.9-1.667/build/include/linux -
DMODULE-Wall -O2 -c -o hellokernel.o hellokernel.c
But, despite my providing what I think should be a directory in which to
search for *.h files (which I believe are the correct ones for my
system, a Fedora Core 3 install) for kernel compilations, I keep getting
the error above based on gcc including the wrong header file.
Thanks in advance for any help!
