Build Problem: bjam + boost + python

Hi,

I've done a svn check_out of the boost repository.
I'm trying to build it with the underlaying options, but
can't achieve that goal
due to the underlaying error messages.

Any help or hints will be appreciated

Cheers
Michael

ps A couple of weeks ago, i was able to compile boost with
the same options
without a problem.

"bin/bjam.exe" -d 0 stage --stagedir=.
--toolset=msvc link=sta
tic runtime-link=shared architecture=x86 release debug
address-model=32

Michael, I think Rene's change
(http:
//svn.boost.org/trac/boost/changeset/39731) should have
fixed
this problem. Could you check whether your copy of
libs/python/build/Jamfile.v2 contains this change?

I've check and perform a svn update and I'm in sync with the
trunk (r40120).
My "libs/python/build/Jamfile.v2" (r39731) has the
changes, but still i can't
build boost due to the failure I've mentioned.
When i turn that file back to the previous version (r39191)
I'm able to build
the library!!!

Should the changes be rolled back?
Cheers
Michael

Maybe; they were an attempt to fix a different problem. 
Could you
please give us a detailed accounting of the steps you're
using to
reproduce the problem, including what's in your *-config.jam
files (if
any) and the directory from which you invoke the build?

Thanks,

Reproducing the problem is quite easy.

1. svn checkout of the trunk, no modification what so
ever...
2. call bjam with the following parameter:

d:devlibsboost>"binbjam.exe" -d 0 stage
--stagedir=. --toolset=msvc
link=static runtime-link=shared architecture=x86 release
debug address-model
=32

warning: Graph library does not contain optional GraphML
reader.
note: to enable GraphML support, set EXPAT_INCLUDE and
EXPAT_LIBPATH to the
note: directories containing the Expat headers and
libraries, respectively.
warning: skipping optional Message Passing Interface (MPI)
library.
note: to enable MPI support, add "using mpi ;" to
user-config.jam.
note: to suppress this message, pass
"--without-mpi" to bjam.
note: otherwise, you can safely ignore this message.

error: Unable to find file or target named
error:     '/python//python_for_extensions'
error: referred from project at
error:     'libs/python/build'


But when "libs/python/build/Jamfile.v2" is rolled
back to r39191, I'm able to
build the library.

Thanks for you help.
Cheers
Michael
