[Lustre-discuss] ubuntu and lustre-client

[chris (fool) mccraw]

hi folks,

i've dug around the archives and googled my head off, but i am drawing
a blank.  is anyone using recent ubuntu as a lustre client?  i realize
that the two latest releases have kernels too new for anyone to have
patched for the client, but ubuntu 10.4 (released over a year ago)
uses kernel 2.6.32 and so i figured i ought to be able to use the
suse-patched kernel source to run under 10.4.  i ran into some
compilation issues that were beyond my immediate understanding and
figured maybe there was someone else out here who has done this who
can offer me some guidance.

once again, i wish to build just the client (with native infiniband
support) on a 2.6.32 client, 64bit.

the specific error i get trying to build the client is:

make  CC="gcc" -C /usr/src/linux-source-2.6.32               \
        -f /home/chris/lustre-1.8.5/build/Makefile
