[Boost-build] [Fwd: Old Python version conflict while building Boost.Python]

From: Matt (mattbenic_at_[hidden])
Date: 2007-09-18 10:53:24

Hi all, I hope I'm directing this to the right group. Please excuse the
long winded explanation but in this case I think it is warranted.

I am trying to build Boost.Python for embedded python scripting (I'm
already familiar with other Boost utilities, though not with lib based
ones). I initially tried downloading and running the boost installer,
but despite being left to run overnight, it did not seem to complete or
download any packages successfully-probably due to company firewall
issues. I then downloaded the latest boost source version (1.34.1) and
extracted that. I mistakenly understood from the Boost.Python docs that
Python 2.2 was the preferred version, and downloaded and installed that.
Running the following:
    cd C:\Work\boost_1_34_1\libs\python\example\quickstart\
    C:\Work\boost_1_34_1\bjam toolset=msvc --verbose-test
--debug-configuration test
caused an error. After some re-reading I realized that 2.2 is the lowest
possible version, but that a newer version is probably better. I
uninstalled Python 2.2 and installed 2.5.1 instead.
Running the following did not result in any errors:
cd C:\Work\boost_1_34_1\
C:\Work\boost_1_34_1\bjam toolset=msvc --with-python stage

However now when I try to run the quickstart, after the line
"capture-output
bin\test_ext.test\msvc-8.0\debug\threading-multi\test_ext" is output, a
missing dll error dialog appears with the message "This application has
failed to start because python22.dll was not found. Re-installing the
application may fix this problem". Filemon indicates that Python.exe is
trying to link to this dll.

I have invoked python on the commandline, and this works fine, so it
seems that this incorrect version linking is only happening through
boost.build.

Does anyone have any suggestions as to what may be wrong? I have scoured
the registry and files and can't figure out what is going on here. Any
help would be greatly appreciated.
