Unable to build Boost.Python

Question

I am trying to build boost.python following this link. When I try to compile using ./b2 or ./bjam, I am getting errors like:

error: No best alternative for /python_for_extensions 
next alternative: required properties: <python>2.6 <target-os>linux 
    matched 
next alternative: required properties: <python>2.6 <target-os>linux 
    matched

The error disappears when I added this line:

using python : 2.6 : /usr/bin/python2.6 : /usr/include/python2.6 : /usr/lib/python2.6 : <python-debugging>on ;

in

/home/kchaitanya/boost/boost_1_50_0/tools/build/v2/user-config.jam

However, when compiling now, I get compile time errors of not being able to find header files. Just a small excerpt of the errors is:

Need help on building this boost.python.

Answer 1

The problem was not installing the python-devel or python-dev package corresponding to my python version.

In my case it was python2.6 so

sudo yum install python26-devel did the trick.

Answer 2

I had a similar issue in my project and above would not help. I was cross-compiling python and boost, and the actual issue for me was duplication of the 'using python : ' in configuration (one existed in project-config.jam, following the bootstrap.sh/bat execution and I was trying to add another python config myself to a user-config.jam).

This solution was described in here: http://comments.gmane.org/gmane.comp.lib.boost.build/22088
