Re: my codes need to include umad.h and mad.h, but I can't find them on windows(win7,64bit) ,Did I missed any package or anything wrong? thanks for your help.

Hi,

you are probably referring to a driver downloaded from the OpenFabrics project.

I am not 100% sure about your question but asking if you mind trying the latest Mellanox buid for the same operating system.
