Just tried to build last night's master tarball on Solaris-11.3 on x86-64 hardware (but keep in mind the default ABI is ILP32).
I see the following fatal error "/shared/OMPI/openmpi-master-solaris11-x86-ib-ss12u5/openmpi-dev-4716-g99b2664/opal/mca/pmix/pmix3x/pmix/src/dstore/pmix_esh.c", line 305: warning: implicit function declaration: flock (E_NO_IMPLICIT_DECL_ALLOWED) "/shared/OMPI/openmpi-master-solaris11-x86-ib-ss12u5/openmpi-dev-4716-g99b2664/opal/mca/pmix/pmix3x/pmix/src/dstore/pmix_esh.c", line 305: undefined symbol: LOCK_EX "/shared/OMPI/openmpi-master-solaris11-x86-ib-ss12u5/openmpi-dev-4716-g99b2664/opal/mca/pmix/pmix3x/pmix/src/dstore/pmix_esh.c", line 321: undefined symbol: LOCK_UN "/shared/OMPI/openmpi-master-solaris11-x86-ib-ss12u5/openmpi-dev-4716-g99b2664/opal/mca/pmix/pmix3x/pmix/src/dstore/pmix_esh.c", line 335: undefined symbol: LOCK_UN "/shared/OMPI/openmpi-master-solaris11-x86-ib-ss12u5/openmpi-dev-4716-g99b2664/opal/mca/pmix/pmix3x/pmix/src/dstore/pmix_esh.c", line 348: undefined symbol: LOCK_UN "/shared/OMPI/openmpi-master-solaris11-x86-ib-ss12u5/openmpi-dev-4716-g99b2664/opal/mca/pmix/pmix3x/pmix/src/dstore/pmix_esh.c", line 369: undefined symbol: LOCK_UN "/shared/OMPI/openmpi-master-solaris11-x86-ib-ss12u5/openmpi-dev-4716-g99b2664/opal/mca/pmix/pmix3x/pmix/src/dstore/pmix_esh.c", line 410: undefined symbol: LOCK_SH "/shared/OMPI/openmpi-master-solaris11-x86-ib-ss12u5/openmpi-dev-4716-g99b2664/opal/mca/pmix/pmix3x/pmix/src/dstore/pmix_esh.c", line 435: undefined symbol: LOCK_UN "/shared/OMPI/openmpi-master-solaris11-x86-ib-ss12u5/openmpi-dev-4716-g99b2664/opal/mca/pmix/pmix3x/pmix/src/dstore/pmix_esh.c", line 444: undefined symbol: LOCK_UN "/shared/OMPI/openmpi-master-solaris11-x86-ib-ss12u5/openmpi-dev-4716-g99b2664/opal/mca/pmix/pmix3x/pmix/src/dstore/pmix_esh.c", line 454: undefined symbol: LOCK_UN "/shared/OMPI/openmpi-master-solaris11-x86-ib-ss12u5/openmpi-dev-4716-g99b2664/opal/mca/pmix/pmix3x/pmix/src/dstore/pmix_esh.c", line 561: undefined symbol: LOCK_UN cc: acomp failed for /shared/OMPI/openmpi-master-solaris11-x86-ib-ss12u5/openmpi-dev-4716-g99b2664/opal/mca/pmix/pmix3x/pmix/src/dstore/pmix_esh.c This is, of course, because flock() is a BSDism not defined by POSIX and therefore not present on SysV systems.
