Re: [C++-sig] Building Boost Python Tutorial Linker Errors

March 23, 2016


      I built boost-python on anaconda on linux using:
https://anaconda.org/meznom/boost-python

Hello,
I have spent the past week trying to build the boost python tutorial, only
to be stopped by numerous linker errors.
I have posted my question on
http://stackoverflow.com/questions/36143494/linker-errors-running-bjam-on-bo...
My system runs Windows 10, Visual Studio 2015 (msvc 14.0), Anaconda 32bit,
Anaconda 64bit, and regular default-installed Python 2.7, and the Boost
1.60.0 libraries (I have tried both 32-bit and 64-bit builds).
I first build my Boost libraries in either 32-bit (bootstrap, b2) or
64-bit (bootstrap, b2 address-model=64), using the instructions at
http://www.boost.org/doc/libs/1_60_0/more/getting_started/windows.html
I then follow the most recent boost.python tutorial at
http://www.boost.org/doc/libs/1_60_0/libs/python/doc/html/tutorial/tutorial/...
...
(which
by the way needs serious work).
I have tried combinations of the following build instructions and msvc /
python settings.
bjam
bjam address-model=64
bjam address-model=64 architecture=x86
using msvc : 14.0 ;
using msvc : 14.0 : "C:/Program Files (x86)/Microsoft Visual Studio
14.0/VC/bin" ;
using msvc ;
using python ;
using python : 2.7 ;
using python : 2.7 : C:/Users/Joey/Anaconda2 ;
using python : 2.7 : "C:/Users/Joey/Anaconda2 (32-bit)" ;
using python
    : 2.7                   # Version
    : C:\\Users\\Joey\\Anaconda2\\python.exe      # Python Path
    : C:\\Users\\Joey\\Anaconda2\\include         # include path
    : C:\\Users\\Joey\\Anaconda2\\libs            # lib path(s)
    : <define>BOOST_ALL_NO_LIB=1
    ;
In any setting, when I run "bjam" I get the following output:
