[Boost-users] Easy linking question

Hi, I compiled for visual studio 2005 (vc8). In my boost lib folder I have a serialization library named: libboost_serialization-vc80-mt-gd-1_33_1.lib everything was working fine until I changed my code generation runtime library from: Multi-threaded Debug DLL (/MDd) to: Multi-threaded Debug (/MTd) Now when I compile I get a linking error saying my app cannot find the lib called: libboost_serialization-vc80-mt-sgd-1_33_1.lib (there is an 's' before the 'gd' which is the difference). I don't have this lib anywhere in my boost folder. What happened! Thanks, Mark
