Getting bjam to build with python in windows

[Mats Carlsson-2]

Hi!

I'm trying to run bjam using this command:
bjam --with-system --with-thread --with-date_time --with-regex
--with-serialization stage

I get a message that tells me that bjam can not find python:
WARNING: No python installation configured and autoconfiguration
         failed.  See http://www.boost.org/libs/python/doc/building.html
         for configuration instructions or pass --without-python to
         suppress this message and silently skip all Boost.Python targets

When running:
bjam --debug-configuration

I get:
notice: [python-cfg] Configuring python...
notice: [python-cfg] Checking interpreter command "python"...
notice: [python-cfg] running command 'DIR /-C /A:S
"C:\Python31\python.exe" 2>&1'
notice: [python-cfg] running command '"python" -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.
notice: [python-cfg] running command 'DIR /-C /A:S

notice: [python-cfg] Details of this Python configuration:
notice: [python-cfg]   interpreter command: "python"
notice: [python-cfg]   include path: "Include"
notice: [python-cfg]   library path: "\libs"
notice: [python-cfg]   DLL search path: "<empty>"

It seems to find python (C:\Python31\python.exe), but I guess it
should use pythonw.exe instead of python.exe. I do not how to get bjam
to look in the right place. I have been looking in some of the
config.jam files, but I do not know how, or if I should change them.

If some one could give some help it would be greatly appreciated.

BR,
/Mats Carlsson

Do you really want the python library to be built (you're not using
"--with-python"), or are you simply concerned over the warnings?

If the former, add "--with-python" to your bjam invocation and read up
under:
http://www.boost.org/doc/libs/1_40_0/libs/python/doc/building.html#configuring-boost-build

If the latter, ignore the warnings. IIRC similar warnings (regarding
libraries not actually being built in the current build request) should have
been fixed in later Boost versions - which version of Boost are you using?

I also get this warning every time I run bjam on windows. Is there a
boost.build configuration file somewhere that I can set it to ignoring
this? If Mats doesn't need python that's probably useful for him too.

I use boost 1.40.0 i suppose. It seems to invoke the --with-python by
default and I get an error message when using the --without-python
(both --with and --without error).

I need python, but I'm not sure if I need it to be built or just
connected to the boost-things. I was told that the python stuff that
came with the boost download did not work properly with the
eclipse/windows setup I have. So I had to build, or somehow get it
connected to my project.

Like I said it seems that bjam is looking in the right place but
choosing the wrong executable (pythonw.exe vs. python.exe). But I'm
new to this so I might be misunderstanding the feedback.

Matt,

Boost 1.40 is not supposed to work with Python 3.* at all -- neither
configuration code, nor Boost.Python codebase is going to work.


Please either try 2.* or use SVN trunk -- which had Python 3.* support
merged.

Ok, I tried with python 2.6. It seems to work better, bjam finds
python (I think):
notice: [python-cfg] Configuring python...
notice: [python-cfg] Registry indicates Python 2.6 installed at "C:\Python26\"

2>&1'

notice: [python-cfg]   DLL search path: "C:\Python26"

But I get some other problems. It seems that the command "cl" is not
found so I get a lot of "...failed compiled-c-c++ ..."

Take a closer look at the debug output. It should tell you which
compiler was detected...
Or just  attach the log and some of the failing commands...

How do I get the log?
