undefined reference to `boost::system::system_category()

Question

I am trying to include boost in my project. It is giving me error

server.cpp:(.text+0x200): undefined reference to `boost::system::generic_category()'

server.cpp:(.text+0x20a): undefined reference to `boost::system::system_category()'

I have linked libboost_system

Answer 1

The error is you're not specifying your source before the libraries:

g++44 -I/include -m32 -lrt server.cpp -o server.exe /lib/libboost_chrono.a /lib/libboost_date_time.a \
/lib/libboost_exception.a /lib/libboost_filesystem.a /lib/libboost_graph.a \
/lib/libboost_iostreams.a /lib/libboost_locale.a /lib/libboost_math_c99.a \
/lib/libboost_math_c99f.a /lib/libboost_math_c99l.a /lib/libboost_math_tr1.a \
/lib/libboost_math_tr1f.a /lib/libboost_math_tr1l.a /lib/libboost_program_options.a \
/lib/libboost_python.a /lib/libboost_random.a /lib/libboost_regex.a \
/lib/libboost_serialization.a /lib/libboost_signals.a /lib/libboost_system.a \
/lib/libboost_thread.a /lib/libboost_timer.a /lib/libboost_wave.a \
/lib/libboost_wserialization.a

Also, there's likely no reason to link every boost library archive ever willed into existence
