[ewg] OFED4.8 build error

Thu Aug 17 14:14:50 PDT 2017

Hi. I was syncing up my git trees with the latest on the OFED server, 
and got an unexpected build error. Thus I tried freshly cloning trees to 
try the build again (without NFS/RDMA). I get the same error (see 
below). This is on RHEL7.3. Am I missing a step or did something change? 
Thanks for your help.
