Hi Chun ping Wang, you seem to understand my problem. You say to run build.bat (see bjam.qbk), it's ok. Then you say to configure my environment. I've set the variables BOOST_ROOT and BOOST_BUILD_PATH but I get the message again. So I ask you what do you mean exactly by "configuring my environment"? Be very clear.(Step by step) Thank You Chun Ping Wang Date: Mon, 25 Jun 2007 07:49:14 -0700From: cablepuff@gmail.comTo: boost-users@lists.boost.orgSubject: Re: [Boost-users] QuestionYou need to build boost most likely with bjam. If your under windows go to tools/jam/src and type build.bat or if under unix ./build.sh and it should automatically build bjam.exe . You might need to configure your enviornment though.
