I can build OpenMPI with FT on my system if I'm using 1.4 source, but if I use any of the 1.5 series, I get hung in a strange "no" loop at the beginning of the compile (see below):
+ ./configure --build=x86_64-unknown-linux-gnu --host=x86_64-unknown-linux-gnu --target=x86_64-redhat-linux-gnu --program-prefix= --prefix=/usr/mpi/intel/openmpi-1.5-ckpt --exec-prefix=/usr/mpi/intel/openmpi-1.5-ckpt --bindir=/usr/mpi/intel/openmpi-1.5-ckpt/bin --sbindir=/usr/mpi/intel/openmpi-1.5-ckpt/sbin --sysconfdir=/usr/mpi/intel/openmpi-1.5-ckpt/etc --datadir=/usr/mpi/intel/openmpi-1.5-ckpt/share --includedir=/usr/mpi/intel/openmpi-1.5-ckpt/include --libdir=/usr/mpi/intel/openmpi-1.5-ckpt/lib64 --libexecdir=/usr/mpi/intel/openmpi-1.5-ckpt/libexec --localstatedir=/var --sharedstatedir=/var/lib --mandir=/usr/share/man --infodir=/usr/share/info --enable-ft-thread --with-ft=cr --enable-opal-multi-threads . . . ============================================================================ == System-specific tests ============================================================================ checking checking for type of MPI_Offset... long long checking checking for an MPI datatype for MPI_Offset...

The system just keeps repeating "no" over and over infinitely. I'm on RHEL6 2.6.32-220.2.1.el6.x86_64. I've tried the following OpenMPI 1.5 series tarballs with the same results: openmpi-1.5.5rc1.tar.bz2 openmpi-1.5.5rc2r25765.tar.bz2 openmpi-1.5.5rc2r25773.tar.bz2 Any guidance is appreciated. Thanks!
