Thanx Sebastian. Indeed, it wasn't linking to boost.System, since i didn't build it. So after building it, i included the path to the directory where i found 'libboost_system-gcc43-mt-1_39.a', and also included the name of the library in the apropriated settings... although that i still getting an error: cannot find -llibboost_system-gcc43-mt-1_39.a And i don't quite get it, since i indicated where to search for the lib, in the project properties -> GCC C++ Linker -> Libraries -> Libraries search path. Can you help getting through this? regards! On Mon, May 18, 2009 at 1:24 PM, Sebastian Redl < sebastian.redl@getdesigned.at> wrote:

Hello everyone,
I'm trying to use boost lib asio in a project on eclipse (running on ubuntu 8.10). So far i'm getting this errors when trying to build the project. '/home/matheus/boost_1_39_0' is where i've unpacked boost lib downloaded from sourceforge.net http://sourceforge.net . I've also set this directory to the include path in eclipse. So, any help?
Description Resource Path Location Type /home/matheus/boost_1_39_0/boost/asio/detail/posix_signal_blocker.hpp undefined reference to `pthread_sigmask' Proxy_Server line 48 C/C++ Problem You're not linking against libpthread. /home/matheus/boost_1_39_0/boost/asio/error.hpp undefined reference to `boost::system::get_system_category()' Proxy_Server line 218 C/C++ Problem And apparently not against Boost.System either.
You should be able to fix these problems in the project settings.
