在AIX上编译boost示例程序

Question

I can successfully compile the simple_ls.cpp with this command:

xlc++  -qstrict -brtl -I /usr/local/include -L /usr/local/lib simple_ls.cpp -lboost_filesystem -o simple_ls

However when I use the exact same syntax with the path_info.cpp command I get this error:

xlc++  -qstrict -brtl -I /usr/local/include -L /usr/local/lib path_info.cpp -lboost_filesystem -o path_info
ld: 0711-317 ERROR: Undefined symbol: .boost::system::generic_category()
ld: 0711-317 ERROR: Undefined symbol: .boost::system::system_category()
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.

Answer 1

您需要将第二个程序与boost_system链接。

xlc++ -qstrict -brtl -I /usr/local/include -L /usr/local/lib path_info.cpp -lboost_filesystem -o path_info -lboost_system
