[Boost-users] boost.python error while ./bjam install

8 May 2009

      I am compiling boost.python libraries by following the procedure given at
http://www.boost.org/doc/libs/1_39_0/more/getting_started/unix-variants.html...
I first configure the build and installation using bootstrap.sh script
$ ./bootstrap.sh --with-python=/usr/bin/python2.5 --with-libraries=python
--prefix=~/work/boost/setup/boost_1_39_0/mybuild

Here are the contents of project-config.jam fie as generated by the script.

    # Boost.Build Configuration
...
# Automatically generated by bootstrap.sh
import option ;
    import feature ;
# Compiler configuration. This definition will be used unless
    # you already have defined some toolsets in your user-config.jam
    # file.
    if ! gcc in [ feature.values <toolset> ]
    {
        using gcc ;
    }
project : default-build <toolset>gcc ;
# Python configuration
    using python : 2.5 : /usr ;
# List of --with-<library> and --without-<library>
    # options. If left empty, all libraries will be built.
    # Options specified on the command line completely
    # override this variable.
    libraries =  --with-python ;
# These settings are equivivalent to corresponding command-line
    # options.
    option.set prefix : ~/work/boost/setup/boost_1_39_0/mybuild ;
    option.set exec-prefix : ~/work/boost/setup/boost_1_39_0/mybuild ;
    option.set libdir : /lib ;
    option.set includedir : ~/work/boost/setup/boost_1_39_0/mybuild/include
;
The output of bootstrap.sh script instructs me to run ./bjam to build while
instructions at the above link say to run ./bjam install
Anyways, I tried both the options but every time I get the same error
...
Class top-level-target already defined
    Aborted
I searched the forums, but this error seems to never be discussed. I am
stuck, please help!
