[lustre-discuss] Building lustre client on Debian fails

[Jan Andersen]

I have a lustre 2.15.3 cluster and need to add Debian 11 and -12 clients. This is what I've done so far:

# git clone git://git.whamcloud.com/fs/lustre-release.git
# git checkout 2.15.3
# sh autogen.sh
# ./configure --disable-server

But make fails:

...

Is this yet another case of the kernel sources having to be exactly the same as the running kernel?
It seems to be a bit difficult to determine whether the source version is correct or not; I haven't
found a Debian source tree that matches precisely.
