Sorry I hadn't seen that and yes I'm running RH7.0 the kernel is
2.2.17-4 and my machine is a Alpha 2100-4/233. I followed the directions
above the 'struct has no member..' errors disappear, but I'm still
having problems. 

I installed the rpm with 'the header files from the kernel that is
actually running'. I now have dir /usr/src/linux-2.2.17 (and a symlink
/usr/src/linux to it). If I now use the given compile command, I get the

So there seams something wrong with current.h:

I'm not really a kernel-building-guru, so I'm not sure what to make of
that. Is this what's supposed to be there? Looks a little bit empty to

Do you think this is the problem or have I just done something wrong?
