I have access to a Linux/x86-64 machine running "Red Hat Enterprise Linux AS release 4" It has a pretty old gcc:
$ gcc --version | head -1 gcc (GCC) 3.4.6 20060404 (Red Hat 3.4.6-3) As shown below, this gcc is rejecting some portion of the atomics. I am certain I've tested ompi-1.5 and 1.6 on this machine w/o any problems, as well as the trunk (probably sometime in late Feb 2012). So, this appears to be a REGRESSION. -Paul make[2]: Entering directory `/home/phhargrove/OMPI/openmpi-1.7rc5-linux-x86_64-psm/BLD/orte/mca/oob/tcp' CC oob_tcp.lo /home/phhargrove/OMPI/openmpi-1.7rc5-linux-x86_64-psm/openmpi-1.7rc5/orte/mca/oob/tcp/oob_tcp.c: In function `mca_oob_tcp_listen_thread': /home/phhargrove/OMPI/openmpi-1.7rc5-linux-x86_64-psm/openmpi-1.7rc5/opal/include/opal/sys/amd64/atomic.h:85: error: inconsistent operand constraints in an `asm' /home/phhargrove/OMPI/openmpi-1.7rc5-linux-x86_64-psm/openmpi-1.7rc5/opal/include/opal/sys/amd64/atomic.h:85: error: inconsistent operand constraints in an `asm' /home/phhargrove/OMPI/openmpi-1.7rc5-linux-x86_64-psm/openmpi-1.7rc5/opal/include/opal/sys/amd64/atomic.h:85: error: inconsistent operand constraints in an `asm' make[2]: *** [oob_tcp.lo] Error 1 make[2]: Leaving directory `/home/phhargrove/OMPI/openmpi-1.7rc5-linux-x86_64-psm/BLD/orte/mca/oob/tcp' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/phhargrove/OMPI/openmpi-1.7rc5-linux-x86_64-psm/BLD/orte' make: *** [all-recursive] Error 1 On Tue, Oct 30, 2012 at 7:01 PM, Ralph Castain <r...@open-mpi.org> wrote: > Hi folks > > We have posted the next release candidate (rc5) for the 1.7.0 release in > the usual place: > > http://www.open-mpi.org/software/ompi/v1.7/ > > Please put it thru the wringer to help us validate it prior to release > later this month.
