Boost.Python dll being skipped on compile

Question

I am new to python programming and am looking to incorporate some C++ dll's into python. I found boost.python to be the most common answer to this issue and have been trying to test it with a simple 'hello world' application that comes with the boost.python package. Following the tutorial at http://www.boost.org/doc/libs/1_54_0/libs/python/doc/tutorial/doc/html/python/hello.html

I am running Windows 7 using Microsoft Visual Studio 10.0.

My python directory is 'C:\Python27', Boost is 'C:\Boost\boost_1_54_0'

I have set the user-config.jam file to using msvc : 10.0 ; and using python : 2.7 : C:\\Python27 ;

When I invoke bjam I get the following..

...failed msvc.link.dll C:\Boost\boost_1_54_0\bin.v2\libs\python\build\msvc-10.0\debug\boost_python-vc100-gd-1_54.dll C:\Boost\boost_1_54_0\bin.v2\libs\python\build\msvc-10.0\debug\boost_python-vc100-gd-1_54.lib C:\Boost\boost_1_54_0\bin.v2\libs\python\build\msvc-10.0\debug\boost_python-vc100-gd-1_54.pdb...

...failed updating 3 targets...
...skipped 7 targets...

All that is created is an .obj file in:

C:\Boost\boost_1_54_0\libs\python\example\tutorial\bin\msvc-10.0\debug

From my basic limited knowledge it appears the files that are relied upon are being removed just before compilation. I have searched long and hard for a solution but to no avail. It feels like I am missing something very elementary.

Thank you.

EDIT: Updating to python 3.3 seems to have gotten me closer. It is no longer removing the two files from bin.v2, but it is still not compiling a .dll or .pyb file.

Answer 1

SOLVED: First I rebuilt boost.python by running b2 toolset=msvc-10.0 --with-python --user-config=user-config.jam --build-type=complete stage in C:\Boost\boost_1_54_0 then I copied the boost_python-vc100-mt-gd-1_54.lib file into the tutorial folder. Not sure this is the best solution but it seems to now be working.

I suggest to mention python installation path in your configuration file:

using python : 2.7 : C:\Python27\;

Did you cd into the same directory where jamroot and hello.cpp is located?
