It is what I try... my machine is Win7 64 bits... maybe there is a problem with this ?

I got this error :

D:/Boost/boost_1_44_0/tools/build/v2\build-system.jam:721: in load
*** argument error
* rule project.load ( jamfile-location )
* called with: ( )
* missing argument jamfile-location
I have check the "build-system.jam:721" and I have :

local first-project-root-module = [ project.load $(first-project-root-location) ] ;
