Hello, I am new to Boost. Python. I am trying to integrate Python with C++ by using Boost Python library. I have used Boost 1.39.0, Boost Jam 3.1.17 and Python 2.5.4. I have problem running example so I would be grateful if someone helps me to solve it. I have built Boost Build with Bjam, using msvc ang gcc tool sets, according to this link: http://www.boost.org/doc/libs/1_40_0/libs/python/doc/building.html with C:\boost_1_39_0\…\quickstart> bjam toolset=msvc --verbose-test test and similar later C:\boost_1_34_0\…\quickstart> bjam toolset=gcc --verbose-test test It have passed the test. I have navigated to C:\boost\boost_1_39_0\libs\python\example\quickstart\bin\msvc-9.0\debug\threading-multi or similar C:\boost\boost_1_39_0\libs\python\example\quickstart\bin\gcc-mingw-3.4.5\debug, started python and tried to import extending module, but I got following error: " This application has failde to start because boost_python-vc90-mt-gd-1.39.dll was not found. Re-installing the application may fix the problem." or similar error message for gcc... I tried to solve by solution : http://selcuk-ozturk.com/post/2009/09/15/C2b2b-and-Python-with-BoostPython-1... Still there is same error message. Anyone have idea? -- Tanja Zaric
