Description:Setting KVERS used to allow building DAHDI for a kernel version different from the current kernel.

It stopped working several months ago.

I tried to set KSRC in addition to KVERS.  It did not help.

I suspect something is wrong with your system.  It works fine for me and I use KSRC regularly.  Is there a .config file in the path that your feeding to KSRC?
By: Vladimir Mikhelson (vmikhelson) 2010-07-08 19:05:01

Yes, there definitely is .config dated July 1, 2010, 69,597 bytes, in the path. I tried both symlinked and direct paths with the same negative.

Unfortunately ended up rebooting with no DAHDI, then built DAHDI, and rebooted again. Too much down time....

With /home/sruffell/linux-2.6/.config

You do not appear to have the sources for the 2.6.32-22-generic kernel installed.
make: *** [modules] Error 1


Granted, the error message in that case appears to be off because I didn't ask it to build against 2.6.32-22-generic (and that is completely driven off the presence of the KVERS variable, which I didn't pass), but the presence of the .config file in the KSRC directory is what the makefile is using to control the build.

My bad. Stupid typo.

2.6.18-194.8.1.e15 vs. 2.6.18-194.8.1.el5.

Please close the case.

Closing.  Thanks for the update.
