Hi, I am building BOOST using VS.net as follows (build goes fine): on the command prompt: cmd>bjam --toolset=msvc cmd>bjam --toolset=msvc --prefix=e:\boost install The installed libraries have "vc" instead of "vc71". The auto_link.hpp tries to link to libraries with "vc71". Is this a known issue? I try to build using the --layout=system as: cmd>bjam --toolset=msvc --layout=system cmd>bjam --toolset=msvc --layout=system install The copied libraries have libname-mt.lib (ex: boost_thread-mt.lib). To link with non-versioned plain libraries, I define BOOST_AUTO_LINK_NOMANGLE in the user.hpp. This tries to link with libname.lib (ex: boost_thread.lib) and that file will not be there. Is there something else I need to do or is it a known problem with this BETA? with best regards, dhruva -- Dhruva Krishnamurthy Contents reflect my personal views only!
