Visual Studio 2008 Also I want to use is on 32bit windows XP and also on 64 bit. So I guess I need it with above 2 configurations (VS2005 SP1 & 2008) both on 32 bit and 64 bit machine. Please confirm. I am using below version - Version 1.35.0 Boost Jam 3.1.16 I am following below steps to build on VS 2005 - * Unzip "boost-jam-3.1.16.zip" and run "build.bat" - As a result "bjam.exe" is created in folder "boost-jam-3.1.16\bin.ntx86" * Unzip "boost_1_35_0.zip" in say "C:\Boost" folder * Copy "bjam.exe" to "C:\Boost\boost_1_35_0" path * Go to command prompt and make current directory as "C:\Boost\boost_1_35_0" * Run the command below (For Microsoft Visual C++ command-line tools from Visual Studio .NET 2005) to build boost bjam "-sTOOLS=vc-8_0" install Regards, Mukund
