Hi Sean.
Hi: I need to build boost under vc 9.0. how do I specify an alternate vdersion of the compiler, I already have vc8 installed. Which compiler will be automatically picked up?
Use Boost Build to build boost. If you have a default vc8 installation that Boost Build can auto-detect then you can just use the toolset=msvc-8.0 command line option. If you do not have a default msvc-8.0 configuration you can configure it yourself in your user-config.jam file by using the 'using' rule. Something like: using msvc : 8.0 : /my/compiler/path/cl.exe : ...extra options... ; And then you can use the toolset=msvc-8.0 option. To see the exact options for configuring the msvc toolset look at the comment for the init rule in tools/msvc.jam. So for example, if you go to your boost library folder (let's call it /boost) and do this: bjam stage --stagedir=. --build-type=complete toolset=msvc-8.0 You should get all the libraries built in the /boost/lib folder. See the comment in the Jamroot file (or type bjam --help) for a more detailed list of options specific to building Boost libraries. Hope this helps. Best regards, Jurko Gospodnetić
