Subject: [OMPI devel] asm/byteorder.h needed in infiniband/cm.h
From: Jon Mason (jon_at_[hidden])
Date: 2008-09-21 18:45:19

While building the current ompi-trunk on top of OFED-1.4, I hit the following
build break:

connect/btl_openib_connect_ibcm.c: In function `ibcm_component_query':
connect/btl_openib_connect_ibcm.c:766: error: implicit declaration of function `__constant_cpu_to_be64'
make[2]: *** [connect/btl_openib_connect_ibcm.lo] Error 1

The line in question is referring to IB_CM_ASSIGN_SERVICE_ID in infiniband/cm.h.
That file does not include a reference to where __constant_cpu_to_be64 is
defined. When I included asm/byteorder.h, everything built fine and all iWARP
tests passed on OMPI trunk.

Below is the patch in question.
