I'm trying to build 1.33.1 on an AMD64 system, using bjam 3.1.12 and build command bjam "-sTOOLS=gcc" stage I get a horrible amount of error output which roughly reads Building Boost.Regex with the optional Unicode/ICU support disabled. Please refer to the Boost.Regex documentation for more information (and if you don't know what ICU is then you probably don't need it). Jamfile:278: in load-jamfiles *** argument error * rule stage ( name : sources + : requirements * : local-build * ) * called with: ( : /home1/rugrchpc/melis/boost_1_33_1/boost/compatibility/cpp_c_headers/cwchar /home1/rugrchpc/melis/boost_1_33_1/boost/compatibility/cpp_c_h eaders/csignal /home1/rugrchpc/melis/boost_1 [...] 1/rugrchpc/melis/boost_1_33_1/boost/pending/detail/int_iterator.hpp /home1/rugrchpc/melis/boost_1_33_1/boost/pending/detail/property.hpp /home1/rugrchpc/melis /boost_1_33_1/boost/pending/detail/disjoint_sets.hpp : <locate>stage <tree-subdirs>/home1/rugrchpc/melis/boost_1_33_1 <target>all : <suppress>true ) * missing argument name /home1/rugrchpc/melis/boost_1_33_1/tools/build/v1/boost-base.jam:2330:see definition of rule 'stage' being called /home1/rugrchpc/melis/boost_1_33_1/tools/build/v1/bootstrap.jam:21: in boost-build /home1/rugrchpc/melis/boost_1_33_1/boost-build.jam:16: in module scope I've tried looking at the Jamfile and line number mentioned, but I can't figure this stuff out. Any clue what is going on?
