Hi Jeff
I wonder why numa.h is not included on a NUMA system. Because of this
reason its unable to build on NUMA machine as well.
You need to ensure that the numactl-devel RPM is installed. This is a
difference between RHEL and SLES. SLES puts everything in 1 package. RHEL
provides a
toolset RPM and a development package.
Could you tell me weather numactl-devel package is installed or
not???
Thanks
pradeep
