[Boost-users] boost mutex linking problem (undefined reference to mutex) on gcc and boost 1.34

Hello, I'm trying to compile a simple program with a boost::mutex in it. It compiles fine, but the linking process shipwrecks: "undefined reference to `boost::mutex::~mutex()' " I'm using ubuntu 8.04 and boost 1.34. When I try to compile the same program on MSVS 2005, it compiles, links and works fine Do I need to link explicitly to certain library? On the web I found sth. about needing to link against posix4 - but that didn't help. Any help appreciated! Regards, Sabine Lorentz
