Hi, I installed openmpi-1.7.3rc2r29276 on my platforms (Solaris Sparc, Solaris x86_64, and Linux x86_64) with Sun C 5.12 and gcc-4.8.0 in 32- and 64-bit versions. On Solaris Sparc I configured with
LIBS="-lgcc_s" \ --with-wrapper-cflags="-std=c11 -m64" \ --with-wrapper-libs="-lgcc_s" \ "-lgcc_s" is neccessary to build Open MPI and later compile MPI programs. tyr openmpi-1.7.3rc2r29276-SunOS.sparc.64_gcc 19 ../openmpi-1.7.3rc2r29276/configure \ --help | grep wrapper-libs --with-wrapper-libs Extra flags to add to LIBS when using wrapper tyr openmpi-1.7.3rc2r29276-SunOS.sparc.64_gcc 20 more config.log This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake. It was created by Open MPI configure 1.7.3rc2, which was generated by GNU Autoconf 2.69.

Perhaps you can even add "-lgcc_s" as a default library to the build process and wrapper compiler. Thank you very much for your help in advance. Kind regards Siegmar
