Hello, I've made an attempt to build Boost from subversion trunk on Solaris 10 on sparc, with gcc-4.6.2. The build didn't succeed, and I'll be looking into ways to make it pass. I've recorded the build in log file which includes all the setup: http://buildfarm.opencsw.org/~maciej/boost-2012-02-29-09-51.log Some highlights: error: No best alternative for libs/context/build/asm_context_sources var/tmp//ccU7e2QF.s: Assembler messages: /var/tmp//ccU7e2QF.s:401: Error: Architecture mismatch on "cas". /var/tmp//ccU7e2QF.s:401: (Requires v9|v9a|v9b; requested architecture is v8.) /opt/csw/lib/gcc/sparc-sun-solaris2.10/4.6.2/include-fixed/sys/feature_tests.h:341:2: error: #error "Compiler or options invalid for pre-UNIX 03 X/Open applications and pre-2001 POSIX applications" In file included from /opt/csw/lib/gcc/sparc-sun-solaris2.10/4.6.2/../../../../include/c++/4.6.2/bits/postypes.h:42:0, from /opt/csw/lib/gcc/sparc-sun-solaris2.10/4.6.2/../../../../include/c++/4.6.2/iosfwd:42, from /opt/csw/lib/gcc/sparc-sun-solaris2.10/4.6.2/../../../../include/c++/4.6.2/ios:39, from /opt/csw/lib/gcc/sparc-sun-solaris2.10/4.6.2/../../../../include/c++/4.6.2/ostream:40, from /opt/csw/lib/gcc/sparc-sun-solaris2.10/4.6.2/../../../../include/c++/4.6.2/iterator:64, from ./boost/next_prior.hpp:15, from ./boost/utility.hpp:17, from ./boost/python/instance_holder.hpp:10, from ./boost/python/object/pointer_holder.hpp:14, from ./boost/python/to_python_indirect.hpp:10, from ./boost/python/converter/arg_to_python.hpp:10, from ./boost/python/call.hpp:15, from ./boost/python/object_core.hpp:14, from ./boost/python/object/enum_base.hpp:8, from libs/python/src/object/enum.cpp:6: There were a couple of other errors, they are in the log file. What the current status of Solaris builds? Is there anyone else building Boost on Solaris 10? Are any of the problems that are in the log file know and possible to work around? Maciej
