there is no directory Build under /lib/modules/ /lib/modules/2.6.20-2925.9.fc7xen

[zhulizhong]

hello, all of FC7 users:
I installed zaptel and asterisk under FC7. compile errors came out. it shows that the dir Build is missing under /lib/modules/2.6.20-2925.9.fc7xen. under /lib/modules/2.6.20-2925.9.fc7xen, there is folder called build, but is link and empty in side. that dir Build should have source and packages. I check the kernel as follow:
[root@test450 2.6.20-2925.9.fc7xen]# uname -a
Linux test450 2.6.20-2925.9.fc7xen #1 SMP Tue May 22 08:53:03 EDT 2007 i686 i686 i386 GNU/Linux
[root@test450 2.6.20-2925.9.fc7xen]#

I also yum installed kernel and kernel-devel. But the kernel installed is kernel-devel-2.6.22.1-41.fc7.
How do i install complete kernel and kernle-devel for 2.6.20-2925.9.fc7xen? does anyone know that? please give me a hand!
thanks!

Hello:
Are you sure you want to use the xen kernel ?
http://fedoraproject.org/wiki/Tools/Xen

yum list | grep kernel

will provide you with of list of the kernel packages available to install via yum.

If you are using kernel-xen, you must install the kernel-xen-devel package instead of kernel-devel.

[zhulizhong]

Is FC7 default kernel is kernel-xen. IS there any FC7 version without xen?

If you don't want Xen don't install it, or remove it after installation.
