Hi there, I have got the latest BGL-Python 0.95 from svn (thanks to John), but I can't build it. My environment: Windows 7 x64, Python 2.66 x86, MPICH2 1.32 x86, VS2010 I have tried the following steps: 1. The boost 1.53 source code distribution dir (newly extracted from the zip package) is E:\boost_1_53_0, the BGL Python 0.95 source code dir is E:\bgl-python_svn_095 2. Add a new environment variable, name: BOOST_ROOT, value: E:\boost_1_53_0 3. Append the boost 1.53 source code distribution dir (E:\boost_1_53_0) to the environment variable "PATH" to expose later built bjam.exe file. 4. Add some lines to the file user-config.jam (E:\boost_1_53_0\tools\build\v2\user-config.jam) import toolset : using ; using python : 2.6 : "C:\\Python266" : "C:\\Python266\\include" : "C:\\Python266\\libs" ; using mpi : : <find-static-library>mpi <library-path>"D:\\Program Files (x86)\\MPICH2\\lib" <include>"D:\\Program Files (x86)\\MPICH2\\include" : "\"D:\\Program Files (x86)\\MPICH2\\mpiexec\"" ; 5. Open the vs2010 commandline window (Visual Studio Command Prompt 2010) 6. Navigate to boost 1.53 source code distribution dir to build the bjam.exe: type bootstrap.bat 7. Then navigate to the BGL-Python-0.95 source code dir and type bjam --prefix=E:\boost_1_53_0\release32 stage toolset=msvc-10.0 variant=release link=static address-model=32 architecture=x86 threading=multi runtime-link=shared install The outputs are: Jamfile.v2:198: in load-aux rule python.get-python-interpreter unknown in module Jamfile E:/boost_1_53_0/tools/build/v2/build\project.jam:323: in load-jamfile E:/boost_1_53_0/tools/build/v2/build\project.jam:62: in load E:/boost_1_53_0/tools/build/v2/build\project.jam:168: in project.find E:/boost_1_53_0/tools/build/v2\build-system.jam:570: in load E:\boost_1_53_0\tools\build\v2/kernel\modules.jam:283: in import E:\boost_1_53_0\tools\build\v2/kernel/bootstrap.jam:142: in boost-build E:\boost_1_53_0\boost-build.jam:17: in module scope E:\bgl-python_svn_095> and the building process stopped. So what is the problem? Thanks. Zhiyu Li
