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_at_python@boost@@YA?AVobject_at_api@12_at_Vstr@12_at_V3412@1_at_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
