Steve,

I found my problem: I am using RHEL-U3 which comes with other version of
the libibverbs library in package libibverbs-devel. This library is installed
in /usr/lib and does not define the function ibv_get_device_list.

I removed the package and dependencies with:
rpm -e udapl udapl-devel libibverbs libibverbs-utils libibverbs-devel

Is there a way to have the old and new openib libs/tools coexist?

Thanks,
Louis
