Hi, Started to explore boost.Python to use C++ classes (.so or .dll) from Python world. I did these, (Windows) downloaded boost 1.54 and unpacked to C:\boost_1_54, Python 3.3 (earlier tried with Python 2.7) installed visuall C++ 2010 Express free edition From Visual studio command prompt, tested example.cpp and got the result. Now struck in getting hellp.cpp and to generate hello_ext.pyd. Looked at posts in stackoverflow and tried similar steps. Still the same. After unpacking boost1.54, I tried these <boost root> C:\boost_1_54>bootstrap.bat C:\boost_1_54>b2 Now it said add C:\boost_1_54 to compiler include path and add c:\boost_1_54\stage\lib to linker paths. Added these two paths to %PATH% environment variable thru advanced settings. Now ran bjam from hello tutorial C:\boost_1_54\libs\python\example\tutorial>bjam hello_ext.pyd is not generated And noted this "LINK : fatal error LNK1104: cannot open file 'boost_python-vc100-mt-gd-1_54.lib' call "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\vcvarsall.b at" x86 >nul link /NOLOGO /INCREMENTAL:NO /DLL /DEBUG /MACHINE:X86 /MANIFEST /subsystem:conso le /out:"bin\msvc-10.0\debug\hello_ext.pyd" /IMPLIB:"bin\msvc-10.0\debug\hello_e xt.lib" /LIBPATH:"C:\Python33\libs" @"bin\msvc-10.0\debug\hello_ext.pyd.rsp" if %ERRORLEVEL% NEQ 0 EXIT %ERRORLEVEL% ...failed msvc.link.dll bin\msvc-10.0\debug\hello_ext.pyd bin\msvc-10.0\debug\he llo_ext.lib bin\msvc-10.0\debug\hello_ext.pdb bin\msvc-10.0\debug\hello_ext.pdb. .. common.copy boost_python-vc100-gd-1_54.dll ..\..\..\..\bin.v2\libs\python\build\msvc-10.0\debug\boost_python-vc100-gd-1_54. dll 1 file(s) copied. ...skipped hello_ext.pyd for lack of hello_ext.pyd... common.mkdir bin\hello.test common.mkdir bin\hello.test\msvc-10.0 common.mkdir bin\hello.test\msvc-10.0\debug ...failed updating 3 targets... ...skipped 1 target... ...updated 41 targets..." If this is basic question, please answer. Or else please direct to appropriate Boost mailing list -- Regards, Ram **
