Failed to build compat-rdma RPM when compiling OFED 3.5.1 on CentOS 5.8

I was compiling OFED 3.5.1 on CentOS 5.8. I have got this error.

make[3]: *** [/var/tmp/OFED_topdir/BUILD/compat-rdma-3.5/compat/main.o] Error 1
make[2]: *** [/var/tmp/OFED_topdir/BUILD/compat-rdma-3.5/compat] Error 2
make[1]: *** [_module_/var/tmp/OFED_topdir/BUILD/compat-rdma-3.5] Error 2
make[1]: Leaving directory `/usr/src/kernels/2.6.18-308.el5-x86_64'
make: *** [kernel] Error 2
error: Bad exit status from /var/tmp/rpm-tmp.99798 (%build)


RPM build errors:

I tried to rebuild the SRPMS directly by using the commands, but it will fail the rpmbuild. For more information on rpmbuild command, you can take a look at Rebuild a Source RPM

# rpmbuild --rebuild ~OFED_HOME/SRPMS/compat-rdma-3.5-OFED.3.5.1.src.rpm

I finally fixed my OFED by installing 1.5.3.2

Unable to remove mpi-selector for OFED 1.5.3 during uninstallation

If  you encounter this error "cannot remove mpi-selector" when uninstalling or even installing OFED package, it is best to exit the package and do a yum remove mpi-selector. Apparently, there there are a number of dependencies to BLAS, Scalapack etc.

# yum remove mpi-selector.

Later you can reinstall the dependencies like BLAS, SCALAPACK etc

Useful Information to compile Infiniband with OpenMPI

Taken from the excellent OpenMPI FAQ. "How do I build Open MPI with support for Open IB (Infiniband), mVAPI (Infiniband), GM (Myrinet), and/or MX (Myrinet)?"

To compile OpenMPI against Infiniband
you only have to specify the directory where its support header files and libraries were installed to Open MPI's configure script

--with-openib=
Build support for OpenFabrics (previously known as "Open IB", for Infiniband and iWARP networks -- note that iWARP support was added in the v1.3 series).

# ./configure --with-openib=/path/to/openib/installation

For more information on myrinet etc, do go to the FAQs.
