Is there any reason why I would be getting this error when compiling my own packages? I just started getting this error. /usr/bin/ld: CMakeFiles/test_client.dir/test_client.o: in function __static_initialization_and_destruction_0(int, int):test_client.cpp(.text+0x1be): error: undefined reference to 'boost::system::get_system_category()' /usr/bin/ld: CMakeFiles/test_client.dir/test_client.o: in function __static_initialization_and_destruction_0(int, int):test_client.cpp(.text+0x1c8): error: undefined reference to 'boost::system::get_generic_category()' /usr/bin/ld: CMakeFiles/test_client.dir/test_client.o: in function __static_initialization_and_destruction_0(int, int):test_client.cpp(.text+0x1d2): error: undefined reference to 'boost::system::get_generic_category()' /usr/bin/ld: CMakeFiles/test_client.dir/test_client.o: in function __static_initialization_and_destruction_0(int, int):test_client.cpp(.text+0x1dc): error: undefined reference to 'boost::system::get_generic_category()' /usr/bin/ld: CMakeFiles/test_client.dir/test_client.o: in function __static_initialization_and_destruction_0(int, int):test_client.cpp(.text+0x1e6): error: undefined reference to 'boost::system::get_system_category()' Robbie
