Hi,
I'm trying to get a dummy PCI driver module to compile (code mostly taken from
the FreeBSD developer's handbook), and I've run into a problem with a couple
of header files. I include the file <sys/buf.h>, and it includes the
following two preprocessor directives:
#include "device_if.h"
#include "bus_if.h"
At the moment I'm compiling this module (main source file called fb.c) in my
home directory using the following Makefile:
----------
# Makefile for the skeleton module
SRCS = fb.c
KMOD = fb
.include <bsd.kmod.mk>
----------
The makefile seems to automatically create an '@' directory linking to
/usr/src/sys, but the two headers device_if.h and bus_if.h do not appear in
this directory alongside buf.h, so there is a preprocessing error in bus.h.
After a bit of diggging, I found that device_if.h and bus_if.h could be found
a few directories further in form /usr/src/sys/compile/XXX/......, so my
question is, how should I set up my Makefile, etc. to allow me to build my
little module?
Btw, I can compile a custom kernel no problem, so I don't think my kernel
sources have got messed up.
thanks,
Alex
