Undefined symbols "boost::system::get_posix_category()" and "boost::system::get_system_category()"
Hello, I'm trying to use the filesystem libraries provided by Boost (1.35) through "boost/filesystem.hpp". I've installed Boost via macports and checked whether or not the installation is up to date, which it is. Moreover, I can use (some) other Boost libraries just fine, but not the abovementioned one. I'm using the following code to access several libraries: ----SNIP---- #include <boost/regex.hpp> #include <boost/signals.hpp> #include <boost/system/error_code.hpp> #include <boost/filesystem.hpp> ---/SNIP---- Including any of the first three libraries works just fine and results in a successful build. However, adding the fourth results in: ----SNIP---- Undefined symbols: "boost::system::get_posix_category()", referenced from: __static_initialization_and_destruction_0(int, int)in test.o __static_initialization_and_destruction_0(int, int)in test.o "boost::system::get_system_category()", referenced from: __static_initialization_and_destruction_0(int, int)in test.o __static_initialization_and_destruction_0(int, int)in test.o ---/SNIP--- Can anybody point me to a solution for this issue? I really prefer using the existing functionality from Boost over wirting them myself... Thanks in advance.

Some Boost library consists of both headers and source files. These source files are usually compiled into a library, which you need to link with. From the error message I would think that you need to link to Boost.System and Boost.Filesystem. Those libraries should have been provided upon installation of Boost. If not, you'll need to figure out how to build them for yourself, or just include the corresponding sources into your project. HTH, Markus
You need to link with both boost_system and boost_filesystem. F. Bron boost-users-bounces@lists.boost.org a écrit sur 17/07/2008 12:28:02 :
