mainly because the distro I use doesn't have the 4.8.1 in its repo, in addition as I don't have root permissions, I'm to install it on to my home folder.

my apologies, not sure how --prefix can help my issue.

I know, thing is, if I run configure on opensm it complains that libumand is missing.
if I run configure on infiniband-diags, it complains opensm is missing.

I've searched ofed download on google, got to the ofed alliance web page, clicked download,and selected 4.8.1 from the folder (latest rc).

that is my question, how can I build libibumad when it merged into infiniband-diags? is there a specific target?

see the first answer.

Thanks,
