[Linux-cluster] Compiling error against kernel-2.6.12.2

[Q.L]

Hi,

When I began to "make" on the RH9.0, I can't pass following errors,
could you help me?
however, it seems no compiling problem happen on a host with FC1.0.
further more, what's the special config required in kernel .config
file for GFS cluster?

Thanks.
