Hi, I get a compiler error because of an illegal semicolon: boost-1_33_1/boost/ptr_container/ptr_map_adapter.hpp:180: error: extra ‘;’ Command exited with non-zero status 1 Removing that semicolon solves the problem. (There was a discussion some time ago about these semicolons at namespace scope, which many compilers ignore; I think it was commonly accepted finally to get rid off those.) Oliver
