C++ Boost: undefined reference to boost::system::generic_category()
You should link in the libboost_system
library. I am not sure about codeblocks, but the g++ command-line option on your platform would be
-lboost_system
Depending on the boost version libboost-system comes with the -mt suffix which should indicate the libraries multithreading capability.
So if -lboost_system
cannot be found by the linker try -lboost_system-mt
.
It's a linker problem. Include the static library path into your project.
For Qt Creator open the project file .pro
and add the following line:
LIBS += -L<path for boost libraries in the system> -lboost_system
In my case Ubuntu x86_64:
LIBS += -L/usr/lib/x86_64-linux-gnu -lboost_system
For Codeblocks, open up Settings->Compiler...->Linker
settings tab and add:
boost_system
to the Link libraries text widget and press OK button.
