Hi, All This is my first message at this mailing list, apologies first if I raised some simple question. I am using Microsoft Visual Studio 2012 Express Version, and Python 2.7. My boost version is 1.54.0. I followed the Boost Library instruction at http://www.boost.org/doc/libs/1_54_0/more/getting_started/windows.html#i nstall-boost-build And successfully build Boost in my computer with a message "The Boost C++ Libraries were successfully built!" My Boost path is "C:\local\boost_1_54_0" Then I want to run Boost.Python, and find it requires to be built separately. So, I found Boost.Python Library instructions at http://www.boost.org/doc/libs/1_54_0/libs/python/doc/building.html#basic -procedure In step 3.1 Basic Procedure, the Boost.Python Library instructions lead me back to Boost Library instruction section 5, at where I installed the Boost.Build at "C:\local\boost_1_54_0\BoostBuild". And "C:\local\boost_1_54_0\BoostBuild\bin" has been added to my Path environment variable. So now I am back to the Boost.Python Library instructions at section 3.1.3. I followed the instruction and cd into the "C:\local\boost_1_54_0\libs\python\example\quickstart". The next step, according to the instruction is : Invoke bjam. Replace the "stage" argument from the example invocation from section 5 of the Getting Started Guide http://www.boost.org/doc/libs/1_54_0/more/getting_started/index.html with "test," to build all the test targets. Also add the argument "--verbose-test" to see the output generated by the tests when they are run. On Windows, your bjam invocation might look something like: C:\boost_1_34_0\...\quickstart> bjam toolset=msvc --verbose-test test Then I got 135 unresolved external errors. One of them is as follows: exec.obj : error LNK2019: unresolved external symbol __imp__PyEval_GetGlobals referenced in function "class boost::python::api::object __cdecl boost::python::eval(class boost::python::str,class boost::python::api::object,class boost::python::api::object)" (?eval@python@boost@@YA?AVobject@api@12@Vstr@12@V3412@1@Z) ..\..\..\..\bin.v2\libs\python\build\msvc-11.0\debug\boost_python-vc110- gd-1_54.dll : fatal error LNK1120: 135 unresolved externals May I know what am I wrong? How can I fix this? Thank you very much. Regards Long Wenlong Wang Risk Analyst, Capquest Group Ltd Email: wwang@capquest.co.uk Fleet 27, Rye Close, Fleet, GU51 2QQ.
