How do I install the Zaptel drivers on a system running Fedora Core?
First, make sure that you have all the needed software dependencies.  The following site should give you a good idea of what software packages you need to install.

http://www.voip-info.org/tiki-index.php?page=Asterisk+Linux+Fedora

After installing the software dependencies, you need to download the kernel source, and make two folders, linux, and either linux-2.4 or linux-2.6, (depending on which kernel you have, 2.4 or 2.6).  Link these two folders to your kernel source directories.

cd /usr/src
ln -s [kernel-source-dir] linux
ln -s [kernel-source-dir] linux-2.4

OR (DEPENDING ON YOUR KERNEL VERSION)

ln -s [kernel-source-dir] linux-2.6

Make sure that where [kernel-source-dir] is, you use the full directory path for the kernel source.  Next try to compile Zaptel.  If compiling fails, issue the following command, and make sure that where [kernel-source-dir] is, you use the full directory path for your kernel source.

cd /usr/src
ln -s [kernel-source-dir] /lib/modules/`uname -r`/build

If Zaptel still doesn't compile, issue these two commands, and then try to compile zaptel.

ln -s /lib/modules/`uname -r`/build /usr/src/linux
ln -s /lib/modules/`uname -r`/build /usr/src/linux-2.4

OR (DEPENDING ON YOUR KERNEL VERSION

ln -s /lib/modules/`uname -r`/build /usr/src/linux-2.6

If that does not work, or you don't have a build directory in your /lib/modules... directory try the following:

cd /usr/src/[kernel-version]
make mrproper
cp /boot/config-[kernel-version] .config


Make sure the EXTRAVERSION variable in the Makefile matches the running kernel if you get strange errors after compiling zaptel upon loading

# here you may need to check EXTRAVERSION in the kernel Makecdfile
make oldconfig
make include/asm
make include/linux/version.h
make SUBDIRS=scripts

If you are running udev, add the following lines into /etc/udev/rules.d/50-udev.rules file and link /dev/zap to /udev/zap (ln -s /udev/zap /dev/zap).
