I have a Creative X-Fi xtremegamer soundcard in my PC. I downloaded the driver and it worked fine so far in my other distro (Linux Mint). However in openSUSE when I try to 'make' and 'make install' (as instructed by the readme) I get the following message (running with su):

HAL9000:/home/susephoenix/Documents/XFiDrv_Linux_Public_US_1.00 # make
make -C /lib/modules/
make[1]: Entering directory `/usr/src/linux-'
make[1]: *** No targets specified and no makefile found. Stop.
make[1]: Leaving directory `/usr/src/linux-'
make: *** [all] Error 2
HAL9000:/home/susephoenix/Documents/XFiDrv_Linux_Public_US_1.00 # make install
Copy module files...
cp: cannot stat `ctxfi.ko': No such file or directory
make: *** [install] Error 1
Just for information when I type 'uname -r' I get this:

susephoenix@HAL9000:~> uname -r
Can anyone tell me from this what I need to do to make the driver install?

PS I have mobo Intel/realtek audio but I really want to make the X-fi work, and especially since I know it works in the other distro.

Thanks in advance!
