5023	Can not build Boost.Python	hacenator@…	Vladimir Prus	"I have installed Python 2.6
when i runing ""bjam"" i have messages:


{{{
warning: No python installation configured and autoconfiguration
note: failed.  See http://www.boost.org/libs/python/doc/building.html
note: for configuration instructions or pass --without-python to
note: suppress this message and silently skip all Boost.Python targets
}}}

After I add add line ""using python : 2.6 ; "" to ""project-config.jam"" I have this warning message again.

Then I add absolute path to python in ""project-config.jam"". This is not working too.

I run bjam with ""--debug-configuration"" option and have messages:

{{{
notice: [python-cfg] running command '""C:\Python26\python.exe"" -c ""from sys import *; print('version=%d.%d\nplatform=%s\nprefix=%s\nexec_prefix=%s\nexecutable=%s' % (version_info[0],version_info[1],platform,prefix,exec_prefix,executable))"" 2>&1'
notice: [python-cfg] ...does not invoke a working interpreter
notice: [python-cfg] No working Python interpreter found.
}}}

But when I run
{{{
""C:\Python26\python.exe"" -c ""from sys import *; print('version=%d.%d\nplatform=%s\nprefix=%s\nexec_prefix=%s\nexecutable=%s' % (version_info[0],version_info[1],platform,prefix,exec_prefix,executable))""
}}}
manualy, I have correct results.

Ok. Next I modify ""tools\build\v2\tools\python.jam""

{{{
local rule shell-cmd ( cmd )
{
    debug-message running command '$(cmd)"" 2>&1""' ;
    x = [ SHELL $(cmd)"" 2>&1"" : exit-status ] ;
    
    debug-message CMD ""$(cmd)"" ; <<<<<<< add this string	
    debug-message RESULT ""$(x)"" ;  <<<<<<< add this string
	
	if $(x[2]) = 0
    {
        return $(x[1]) ;
    }
    else
    {
        return ;
    }
}
}}}

and run ""bjam --debug-configuration"" again

Result:

{{{
notice: [python-cfg] running command '""C:\Python26\python.exe"" -c ""from sys import *; print('version=%d.%d\nplatform=%s\nprefix=%s\nexec_prefix=%s\nexecutable=%s' %(version_info[0],version_info[1],platform,prefix,exec_prefix,executable))"" 2>&1'

}}}

I don't know why he is trim command.
