It seems like there is no more support the SGI mipspro compiler? When I tried to build the boost libraries I got the following message mipspro.jam: No such file or directory .../boost_1_34_0/tools/build/v2/build/toolset.jam:27: in toolset.using rule mipspro.init unknown in module toolset. .../boost_1_34_0/tools/build/v2/build/project.jam:825: in using user-config.jam:5: in modules.load .../boost_1_34_0/tools/build/v2/build-system.jam:138: in load .../boost_1_34_0/tools/build/v2/kernel/modules.jam:261: in import .../boost_1_34_0/tools/build/v2/kernel/bootstrap.jam:132: in boost-build .../boost_1_34_0/boost-build.jam:9: in module scope Not all Boost libraries built properly. -- Sébastien Fortier
