[mvapich-discuss] mvapich2-2.0rc1: configure: error: 'infiniband/mad.h not found. Please retry with --disable-mcast'

[Yanfei Wang]

Hi,

some troubles from installing mvapich2-2.0rc1 on Centos6u3 with
mellanox VPI HCA, and MLNX_OFED_LINUX-2.1-1.0.6-rhel6.3-x86_64.tgz.
error:
configure: error: 'infiniband/mad.h not found. Please retry with
--disable-mcast'

use --disable-mcast can fix this error, and I want to know whether
this action can disable some features that have impact on MPI
performance on RoCE environments?


Thanks
Yanfei
