I installed Boost 1.47 from haikuware but I have a problem building with it. I did the standard install to /boot. I can see libboost_thread.so.1.47.0 in /boot/common/lib. But when I try to link against it I get unresolved symbols for boost::thread. I am building POVRay and when I specify it with: ./configure --with-boost-thread=/boot/common/lib I get some odd results: checking for boostlib >= 1.37... yes checking for exit in -l/boot/common/lib... no checking for exit in -lboost_thread-/boot/common/lib... no configure: error: Could not link against boost_thread-/boot/common/lib If I run nm against it I get symbols, so it looks well-formed. Any advice is appreciated. Thanks, Andrew
