Hi, I'm using Boost 1.34.1 with MS VC8. Release version of my project will link to the debug version of static library (libboost_program_options-vc80-mt-sgd-1_34_1.lib). This will cause some link error (symbol redefinition in debug and release version of system library). How can I link to the release version of the library(libboost_program_options-vc80-mt-s-1_34_1.lib)? Thanks! MQ Gu
