In 1.7.4rc1's README support is still claimed for Solaris 11 on x86_64 with Sun Studio (12.2 and 12.3): - Oracle Solaris 10 and 11, 32 and 64 bit (SPARC, i386, x86_64), with Oracle Solaris Studio 12.2 and 12.3
However, I get a build failure when configured with: CC=cc CFLAGS=-m64 --with-wrapper-cflags=-m64 CXX=CC CXXFLAGS='-m64 -library=stlport4' --with-wrapper-cxxflags=-m64 FC=f90 FCFLAGS=-m64 --with-wrapper-fcflags=-m64 --with-openib --prefix=... The failure doesn't appear to be compiler specific, and I will be testing gcc ASAP. make[2]: Entering directory `/shared/OMPI/openmpi-1.7.4rc1-solaris11-x64-ib-ss12u3/BLD/opal/mca/if/posix_ipv4' CC if_posix.lo "/shared/OMPI/openmpi-1.7.4rc1-solaris11-x64-ib-ss12u3/openmpi-1.7.4rc1/opal/include/opal/sys/amd64/atomic.h", line 136: warning: parameter in inline asm statement unused: %3 "/shared/OMPI/openmpi-1.7.4rc1-solaris11-x64-ib-ss12u3/openmpi-1.7.4rc1/opal/include/opal/sys/amd64/atomic.h", line 182: warning: parameter in inline asm statement unused: %2 "/shared/OMPI/openmpi-1.7.4rc1-solaris11-x64-ib-ss12u3/openmpi-1.7.4rc1/opal/include/opal/sys/amd64/atomic.h", line 203: warning: parameter in inline asm statement unused: %2 "/shared/OMPI/openmpi-1.7.4rc1-solaris11-x64-ib-ss12u3/openmpi-1.7.4rc1/opal/include/opal/sys/amd64/atomic.h", line 224: warning: parameter in inline asm statement unused: %2 "/shared/OMPI/openmpi-1.7.4rc1-solaris11-x64-ib-ss12u3/openmpi-1.7.4rc1/opal/include/opal/sys/amd64/atomic.h", line 245: warning: parameter in inline asm statement unused: %2 "/shared/OMPI/openmpi-1.7.4rc1-solaris11-x64-ib-ss12u3/openmpi-1.7.4rc1/opal/mca/if/posix_ipv4/if_posix.c", line 272: undefined struct/union member: ifr_hwaddr "/shared/OMPI/openmpi-1.7.4rc1-solaris11-x64-ib-ss12u3/openmpi-1.7.4rc1/opal/mca/if/posix_ipv4/if_posix.c", line 272: warning: left operand of "." must be struct/union object "/shared/OMPI/openmpi-1.7.4rc1-solaris11-x64-ib-ss12u3/openmpi-1.7.4rc1/opal/mca/if/posix_ipv4/if_posix.c", line 272: cannot access member of non-struct/union object cc: acomp failed for /shared/OMPI/openmpi-1.7.4rc1-solaris11-x64-ib-ss12u3/openmpi-1.7.4rc1/opal/mca/if/posix_ipv4/if_posix.c make[2]: *** [if_posix.lo] Error 1 make[2]: Leaving directory `/shared/OMPI/openmpi-1.7.4rc1-solaris11-x64-ib-ss12u3/BLD/opal/mca/if/posix_ipv4' The atomics warnings are concerning (and appear *MANY* times in the output). However the *real* problem is the three errors in opal/mca/if/posix_ipv4/if_posix.c", line 272 Solaris does't have a ifr_hwaddr field in struct if_req. It *does* have an ifr_addr field, but this posting: http://comments.gmane.org/gmane.os.solaris.opensolaris.networking/12839 suggests that this ioctl probably fails on PF_INET sockets. The surrounding code looks like: #ifdef SIOCGIFHWADDR /* get the MAC address */ if (ioctl(sd, SIOCGIFHWADDR, ifr) < 0) { opal_output(0, "btl_usnic_opal_ifinit: ioctl(SIOCGIFHWADDR) failed with errno=%d", errno); break; } memcpy(intf->if_mac, ifr->ifr_hwaddr.sa_data, 6); #endif #if defined(SIOCGIFMTU) && defined(HAVE_STRUCT_IFREQ_IFR_MTU) /* get the MTU */ if (ioctl(sd, SIOCGIFMTU, ifr) < 0) { opal_output(0, "btl_usnic_opal_ifinit: ioctl(SIOCGIFMTU) failed with errno=%d", errno); break; } intf->if_mtu = ifr->ifr_mtu; #endif Note the "btl_usnic_open_ifinit:" in the opal_output lines is probably a cut-and-paste error. -Paul -- Paul H.
