Hello, I'm trying to build and run Boost.Test test suite on trunk. From a fresh checkout, using cygwin and targeting msvc-8.0 I did first from the boost root directory : ./bootstrap.bat This went fine, then just to be sure I did : ./bjam.exe toolset=msvc-8.0 --with-test Which also went fine. Then I switched to libs/test/test and did : ../../../bjam.exe toolset=msvc-8.0 Which failed with : ..\..\..\libs\test\build\Jamfile.v2:107: in modules.load rule boost-install unknown in module Jamfile</D:/dev/perso/cpp/boost/libs/test/build>.
