[linux-lvm] Problem at compiling kernel 2.4.18 with lvm 1.0.7

[Krisztian Gyoerffy]

Hello Heinz,


no I haven't, because till now I ever patched my kernels with any of the
LVM versions I chose to compile the kernel by myself. And it was ok.
This is the first time that I get a compilation error like this.

Can we fix the problem somehow, that I can compile then kernel with the
LVM patch 1.0.7?

Because to tell the truth I don't really rely on that rpm from suse,
since I had big troubles with an apache rpm, and finaly it turned out
that there was a failure in it, and when I compiled apache from the
source it was ok.


Thanks a lot

Krisztian

Krisztian,

running the SuSE LVM rpm with the SuSE kernel should work fine.
Have you tried that yet ?
