I just tried to migrate our project from 1.43 -> 1.46.1 but am getting a compilation error with g++ 4.4.3: gcc.compile.c++ bin.v2/libs/filesystem/build/gcc-arm/release/link-static/threading-multi/v3/src/operations.o In file included from boost/filesystem/v3/operations.hpp:25, from libs/filesystem/v3/src/operations.cpp:52: boost/filesystem/v3/path.hpp: In function `std::basic_ostream<_CharT, _Traits>& boost::filesystem3::operator<<(std::basic_ostream<_CharT, _Traits>&, const boost::filesystem3::path&)': boost/filesystem/v3/path.hpp:583: error: parse error before `>' token The build works fine on with microsoft toolchain. Anyone seen this and have a patch? -- *Adam Crain* Chief Platform Architect, GEC Office: 919.836.9916 Cell: 919.428.1002 acrain@greenenergycorp.com *Green Energy Corp,* *enabling the smart grid of the future.** * *www.greenenergycorp.com* *www.totalgrid.org*
