building external modules

[Patrice Dumas]

Hi,

Since the kernel is 2.6, I have trouble compiling and installing an external 
module. I could only compile the driver as root. And before I compile it I 
had to do the following as root:

* edit the Makefile in /usr/src/kernel-2.6.... and remove 'custom' from the
  EXTRAVERSION. Otherwise it isn't installed at the right place.
* run 
  make oldconfig
  make prepare

If I try to compile as a user, I get
[pat@localhost driver]$ make
make  -C /usr/src/linux SUBDIRS=/home/pat/src/eagleusb/driver modules
make[1]: Entering directory `/opt/fc2t/usr/src/linux-2.6.3-1.118'
  HOSTCC  scripts/modpost.o
cc1 : Permission non accordée : ouverture du fichier de dépendances

make[1]: *** [scripts] Erreur 2
make[1]: Leaving directory `/opt/fc2t/usr/src/linux-2.6.3-1.118'
make: *** [eagle-usb.ko] Erreur 2

If I can compile the driver, as root, I get:
[root@localhost driver]# make
make  -C /usr/src/linux SUBDIRS=/home/pat/src/eagleusb/driver modules
make[1]: Entering directory `/opt/fc2t/usr/src/linux-2.6.3-1.118'
  HOSTCC  scripts/modpost.o
  HOSTLD  scripts/modpost

Well, it works.

It is in line with what I have seen on some docs about the building of 
modules, but I am not very comfortable with that. First I don't like to build
as root and second I don't know what to do for rpm building. What should I
do to build modules as non root, and build rpms for the module ?

I searched for informations on that subject but I haven't found anything.
