[Boost-users] bjam - unable to generate "libboost_system-vc80-mt-gd-1_39.lib"

Hi, I am new to boost. I compiled boost using bjam without giving any command line options. I was trying to run a simple asio's timer1.cpp tutorial given on the boost website. It failed with the error "LINK : fatal error LNK1104: cannot open file 'libboost_system-vc80-mt-gd-1_39.lib'" Looked in <BoostRootDir>\bin.v2 directory. There were library files with the format "libboost_system-vc80-mt-1_39.lib" My question is .. What other options needs to be given to bjam to generate suitable libs with "-gd" in the library name. ? "bjam's --help" has not helped on how to fine tune it. Please advice. with thanks & regards, raja koduru
