I'm relatively new to OFED but happened to bump into a similar build issue two weeks ago. The OFED package itself does include XRC support. The issue here (my guess) is that its build script needs to understand the running system's kernel version to decide what should be pulled (from the source). Linux 3.1 could be too new for OFED build script to make a correct decision. Nevertheless, mix-matching OFED modules/libraries is a *bad* idea. It is difficult to love OFED build :) but it seems to work ok (so far for me). Plus, I don't have a better proposal myself anyway ..... -- Wendy -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
