Intermediate Linux users and Linux newbies are often turned away from Linux because they can't get a particular driver to work.
If the driver isn't available in a .rpm, things can get complicated, read compiling from source...
On top of that a standard SUSE 10 install requires some upfront steps before a driver can be compiled without errors.
SUSE Linux 10 with kernel 188.8.131.52
I did only test the below explained procedure on a SUSE 10, but it should work on SUSE 9.x aswell (if you alter the kernel version numbers).
PreparationFirst make sure you have installed the kernel-sources, and the version of the sources is correct.
If you don't know what kernel version is currently installed on your SUSE try:
It should come back with something like:
Linux version 2.6.13-15-default (geeko@buildhost) (gcc version 4.0.2 20050901 (prerelease) (SUSE Linux)) #1 Tue Sep 13 14:56:15 UTC 2005
telling you that you are using version 2.6.13-15-default.
To see if sources are installed you can either startup YaST (software management) or just type:
rpm -qa kernel*
On my system this returns:
kernel-update-tool-0.9-10 kernel-docs-2.6.13-15 kernel-default-2.6.13-15 kernel-source-2.6.13-15 kernel-default-nongpl-2.6.13-15
Note the line kernel-source.
We also will need make and gcc, test for this the same way:
rpm -qa make gcc make-3.80-188 gcc-4.0.2_20050901-3
If any of these packages are missing install them using YaST.
Now log in into a root console (superuser) and configure the compile environment to reflect your actual set up.
cd /usr/src/linux make cloneconfig make modules_prepare
That last statement should comeback with something like:
CHK /usr/src/linux-2.6.13-15/include/linux/version.h make: `arch/i386/kernel/asm-offsets.s' is up to date.
As with everything with Linux things can be donme in different ways.
The same as above can be achieved by executing the following as root:
cp /usr/src/linux-2.6.13-15-obj/i386/default/.config /usr/src/linux/.config cp /usr/src/linux-2.6.13-15-obj/i386/default/scripts/mod/modpost /usr/src/linux/scripts/modpost cp /usr/src/linux-2.6.13-15-obj/i386/default/scripts/genksyms/genksyms /usr/src/linux/scripts/genksyms/genksyms cp /usr/src/linux-2.6.13-15-obj/i386/default/scripts/basic/fixdep /usr/src/linux/scripts/basic/fixdep cp /usr/src/linux-2.6.13-15-obj/i386/default/scripts/mod/modpost /usr/src/linux/scripts/mod/modpost
If you don't do these steps chances are big you get a
/bin/sh scripts/basic/fixdep: File not found
error when trying to compile the driver(s) you need.
To make things complete, you also need to put Module.symvers into the right place.
cp /boot/symvers-2.6.13-15-i386-default.gz /usr/src/linux mv symvers-2.6.13-15-i386-default.gz Module.symvers.gz gunzip /usr/src/linux/Module.symvers.gz make modules_prepareWhatever approach you use, you are now ready to compile a kernel module.
Note: If you run a YaST update and a new kernel gets installed you might want to download the new kernel sources too, and adjust your compile environment, and recompile the driver(s).
Example: Getting a Logitech Quickam (Zoom) working under SUSE Linux 10
cd /usr/local/src wget http://www.saillard.org/linux/pwc/files/pwc-10.0.9-rc1.tar.bz2
(take a peek in http://www.saillard.org/linux/pwc/files to see the current release of this driver)
tar xjf pwc-10.0.9-rc1.tar.bz2 cd pwc-10.0.9-rc1 make make install modprobe pwc
Done! Fire up XawTV and start playing.
