Hi,
I've been trying to install openmpi 1.2.5 on my cluster system running RHEL 4 (x64) with OFED 1.3. I need openmpi 1.2.5 (32 bit) and OFED seems to only install 64 bit version. I tried to build OFED with 32 bit support but it failed so I figure it's best to just compile 32 bit openmpi. I followed the FAQ and few user experience on the web. I ran this command: ./configure --prefix=/usr/mpi/gcc/32bit --with-openib=/usr CFLAGS=-m32 CXXFLAGS=-m32 FFLAGS=-m32 FCFLAGS=-m32 and after few scrolling lines, it stops here: --- MCA component btl:openib (m4 configuration macro) checking for MCA component btl:openib compile mode... dso looking for header without includes checking infiniband/verbs.h usability... yes checking infiniband/verbs.h presence... yes checking for infiniband/verbs.h... yes looking for library without search path checking for ibv_open_device in -libverbs... no looking for library in lib checking for ibv_open_device in -libverbs... no looking for library in lib64 checking for ibv_open_device in -libverbs... no checking for ibv_create_srq... no checking for ibv_get_device_list... no checking for ibv_resize_cq... no configure: WARNING: OpenFabrics support requested (via --with-openib) but not fo und. configure: WARNING: If you are using libibverbs v1.0 (i.e., OFED v1.0 or v1.1), you *MUST* have both the libsysfs headers and libraries installed. Later versio ns of libibverbs do not require libsysfs. configure: error: Aborting. What went wrong? From the error it says early OFED version which is not the one I'm using (running OFED 1.3 now). Any advice is greatly appreciated. -- Thank you. azri
