[Boost-users] Python quickstart hanging on build with bjam

Subject: [Boost-users] Python quickstart hanging on build with bjam

Hi,

I have downloaded boost_1_49_0 to my Mac with OS X 10.5.8. I then ran:

In the home folder I have:

using python : 3.1 : /Library/Frameworks/Python.framework/Versions/3.1/bin/python3.1 ;

In user-config.jam.

I then ran the following:

***
***    Start Screen dump 1
***

$ ./bjam --with-python --user-config=user-config.jam

Building the Boost C++ Libraries.

Component configuration:

    - chrono                   : not building
    - date_time                : not building
    - exception                : not building

The Boost C++ Libraries were successfully built!
         
The following directory should be added to compiler include paths:
         
    /Users/me/Desktop/boost_1_49_0
     
The following directory should be added to linker library paths:

If I  enter bin/darwin-4.0.1/debug, I get this for ls -al:

Why am I hanging? I'd like to get python3 to work with boost but maybe its best to fix the hanging problem first.

Thanks,

Barry
