[linux-lvm] Problems compiling userland LVM on sparc debian unstable

[Chris Danis]

Hello all,

I'm running Debian unstable on a Sparcstation 20. I've managed to
patch the kernel (2.4.14) fine, but I can't seem to get the userspace
tools to compile. There seems to be some kind of conflict with the
headers, but not knowing much C, I'm a bit at a loss for what is going
on.

The build looks like this:

Any advice, of course, would be greatly appreciated.

Argh. This is because lvm.h pulls in kernel header files when compiling
user-mode programs, which it really shouldn't.

The following patch should make it compile OK (it works on my SPARC machine
running woody) even though it's more than a little naff!
