Unloading DAHDI hardware modules: done

2)then i start to untar the DAhdi 2.6.1 package and type
make all && make install (according to the readme file given in the package). it sucessfull install

Error: missing /dev/dahdi!

PLEASE can any one help…

Based on what you wrote here, best guess is that your running kernel doesn’t match the kernel that you built / installed against.

Normally the problem is the other way round, that it always tries to build against the installed kernel and fails if matching -devel packages are missing.

Something that confuses me, here, is references to symlinking the kernel. I wonder if he’s tried to trick it to get round that problem, but not completely succeeded?
