Good Day, This is my first post, so excuse me if I am unfamiliar with protocol. When I execute, bjam "-sTOOLS=gcc" install from the command line, I get the following errors: ...failed gcc-Link-action bin/boost/libs/program_options/build/libboost_program_options.so/gcc/release/shared-linkable-true/threading-multi/libboost_program_options-gcc-mt-1_33_1.so... ...skipped <@boost!lib>libboost_program_options-gcc-mt-1_33_1.so for lack of <@boost!libs!program_options!build/libboost_program_options.so/gcc/release/shared-linkable-true/threading-multi>libboost_program_options-gcc-mt-1_33_1.so... ...skipped <@boost!lib>libboost_wserialization-gcc-d.so for lack of <@boost!lib>libboost_wserialization-gcc-d-1_33_1.so.1.33.1... ...skipped <@boost!lib>libboost_wserialization-gcc-mt-d.so for lack of <@boost!lib>libboost_wserialization-gcc-mt-d-1_33_1.so.1.33.1... ...skipped <@boost!lib>libboost_wserialization-gcc.so for lack of <@boost!lib>libboost_wserialization-gcc-1_33_1.so.1.33.1... ...skipped <@boost!lib>libboost_wserialization-gcc-mt.so for lack of <@boost!lib>libboost_wserialization-gcc-mt-1_33_1.so.1.33.1... ...failed updating 46 targets... ...skipped 54 targets... root[boost_1_33_1]# What does this mean?
