$ cd /lib/modules/$(uname -r)/
$ rm build
$ ln -s source build
$ cd build/
$ su
(root password)
$ make mrproper
$ make cloneconfig
$ make prepare-all

Important: You must change

make prepare-all

to

make prepare scripts


if you get an error similar to:
/bin/sh: scripts/genksyms/genksyms: No such file or directory

Cannot Load Zaptel module because crc_ccitt table not found

This is because you are missing the crc_ccitt library routine.
Go to /lib/modules/$(uname -r)/build
type:

#>make menuconfig

In the ncurses utility,
Go to Library routines
Include:
CRC-CCITT functions
(save) and (exit)

to build modules, type:
make modules

This will rebuild all your modules, including crc-ccitt. After you are done, the crc-ccitt module will be located in ./lib

copy the crc-ccitt.ko (for 2.6 kernels) or crc-ccitt.o (for 2.4 kernels)to /lib/modules/$(uname -r)/kernel/lib/

Installing Wanpipe on SuSe

(Only for the version before 10.1)
http://sangoma.editme.com/wanpipe-linux-asterisk-appendix#WanpipeOnSuse

The wanpipe drivers assume the kernel source is located in /lib/modules/$(uname -r)/build. and in SuSe, this symbolic link points to the headers only. There is a symbolic link in /lib/modules/$(uname -r)/source that points to the kernel source.

To compile on SuSe:

1. Apply the current kernel configuration.
Copy .config file from headers to source

#>cp /lib/modules/$(uname -r)/build/.config /lib/modules/$(uname -r)/source/.config

Set the symbolic link in /lib/modules/$(uname -r)/build to point to the kernel source
#>cd /lib/modules/$(uname -r)
#>mv build build_old
Find the location of your source:
#>ls -al source
It will look like this: source -> /usr/src/linux-2.6.11.4-20a (adjust for your current kernel version)
Create a symbolic link toyour kernel source with name build
#>ln -s /usr/src/linux-2.6.11.4-20a build
Update current configurations from the .config file
#>cd build
#>make menuconfig
#>make prepare-all
