Hi
From your description, it seems that only the multi-threaded libraries are installed.
Actually, the full list is the following one : libboost_date_time-mt.a libboost_date_time-mt-d.a libboost_date_time-mt-d.so libboost_date_time-mt-d.so.1.37.0 libboost_date_time-mt.so libboost_date_time-mt.so.1.37.0 libboost_filesystem-mt.a libboost_filesystem-mt-d.a libboost_filesystem-mt-d.so libboost_filesystem-mt-d.so.1.37.0 libboost_filesystem-mt.so libboost_filesystem-mt.so.1.37.0 libboost_graph-mt.a libboost_graph-mt-d.a libboost_graph-mt-d.so libboost_graph-mt-d.so.1.37.0 libboost_graph-mt.so libboost_graph-mt.so.1.37.0 libboost_iostreams-mt.a libboost_iostreams-mt-d.a libboost_iostreams-mt-d.so libboost_iostreams-mt-d.so.1.37.0 libboost_iostreams-mt.so libboost_iostreams-mt.so.1.37.0 libboost_math_c99f-mt.a libboost_math_c99f-mt-d.a libboost_math_c99f-mt-d.so libboost_math_c99f-mt-d.so.1.37.0 libboost_math_c99f-mt.so libboost_math_c99f-mt.so.1.37.0 libboost_math_c99l-mt.a libboost_math_c99l-mt-d.a libboost_math_c99l-mt-d.so libboost_math_c99l-mt-d.so.1.37.0 libboost_math_c99l-mt.so libboost_math_c99l-mt.so.1.37.0 libboost_math_c99-mt.a libboost_math_c99-mt-d.a libboost_math_c99-mt-d.so libboost_math_c99-mt-d.so.1.37.0 libboost_math_c99-mt.so libboost_math_c99-mt.so.1.37.0 libboost_math_tr1f-mt.a libboost_math_tr1f-mt-d.a libboost_math_tr1f-mt-d.so libboost_math_tr1f-mt-d.so.1.37.0 libboost_math_tr1f-mt.so libboost_math_tr1f-mt.so.1.37.0 libboost_math_tr1l-mt.a libboost_math_tr1l-mt-d.a libboost_math_tr1l-mt-d.so libboost_math_tr1l-mt-d.so.1.37.0 libboost_math_tr1l-mt.so libboost_math_tr1l-mt.so.1.37.0 libboost_math_tr1-mt.a libboost_math_tr1-mt-d.a libboost_math_tr1-mt-d.so libboost_math_tr1-mt-d.so.1.37.0 libboost_math_tr1-mt.so libboost_math_tr1-mt.so.1.37.0 libboost_prg_exec_monitor-mt.a libboost_prg_exec_monitor-mt-d.a libboost_prg_exec_monitor-mt-d.so libboost_prg_exec_monitor-mt-d.so.1.37.0 libboost_prg_exec_monitor-mt.so libboost_prg_exec_monitor-mt.so.1.37.0 libboost_program_options-mt.a libboost_program_options-mt-d.a libboost_program_options-mt-d.so libboost_program_options-mt-d.so.1.37.0 libboost_program_options-mt.so libboost_program_options-mt.so.1.37.0 libboost_python-mt.a libboost_python-mt-d-py25.a libboost_python-mt-d-py25.so libboost_python-mt-d-py25.so.1.37.0 libboost_python-mt-d-py26.a libboost_python-mt-d-py26.so libboost_python-mt-d-py26.so.1.37.0 libboost_python-mt-py25.a libboost_python-mt-py25.so libboost_python-mt-py25.so.1.37.0 libboost_python-mt-py26.a libboost_python-mt-py26.so libboost_python-mt-py26.so.1.37.0 libboost_python-mt.so libboost_regex-mt.a libboost_regex-mt-d.a libboost_regex-mt-d.so libboost_regex-mt-d.so.1.37.0 libboost_regex-mt.so libboost_regex-mt.so.1.37.0 libboost_serialization-mt.a libboost_serialization-mt-d.a libboost_serialization-mt-d.so libboost_serialization-mt-d.so.1.37.0 libboost_serialization-mt.so libboost_serialization-mt.so.1.37.0 libboost_signals-mt.a libboost_signals-mt-d.a libboost_signals-mt-d.so libboost_signals-mt-d.so.1.37.0 libboost_signals-mt.so libboost_signals-mt.so.1.37.0 libboost_system-mt.a libboost_system-mt-d.a libboost_system-mt-d.so libboost_system-mt-d.so.1.37.0 libboost_system-mt.so libboost_system-mt.so.1.37.0 libboost_thread-mt.a libboost_thread-mt-d.a libboost_thread-mt-d.so libboost_thread-mt-d.so.1.37.0 libboost_thread-mt.so libboost_thread-mt.so.1.37.0 libboost_unit_test_framework-mt.a libboost_unit_test_framework-mt-d.a libboost_unit_test_framework-mt-d.so libboost_unit_test_framework-mt-d.so.1.37.0 libboost_unit_test_framework-mt.so libboost_unit_test_framework-mt.so.1.37.0 libboost_wave-mt.a libboost_wave-mt-d.a libboost_wave-mt-d.so libboost_wave-mt-d.so.1.37.0 libboost_wave-mt.so libboost_wave-mt.so.1.37.0 libboost_wserialization-mt.a libboost_wserialization-mt-d.a libboost_wserialization-mt-d.so libboost_wserialization-mt-d.so.1.37.0 libboost_wserialization-mt.so libboost_wserialization-mt.so.1.37.0
So you might need -lboost_filesystem-mt rather than - lboost_filesystem.
You mean that I should use -lboost_filesystem-mt instead of -lboost_filesystem ? If that is the case I just tried to use these options and the seem to be working. But there is one remaining problem, I get an error like this : /usr/include/boost/system/error_code.hpp:205: undefined reference to `boost::system::get_posix_category()' My compilation options are : -lboost_filesystem-mt -lboost_thread-mt -lboost_system-mt. Thanks for the help. Johan Mazel
