[C++-sig] boost.python w/ boost.build v2 (was Re: Boost.Python, MinGW, & ImportError)

[Corey Wright]

wow, it's hard finding straight forward documentation on building
boost.python (including examples) with boost.build v2.  lots of practical
stuff for v1, lots of general purpose documentation on v2, but google and i
had a hard finding any step-by-step instructions for using v2.  (maybe i
was looking too hard for something specific to boost.python.)

i started with boost.python from 1.33.1 and mingw and got nowhere.  i
peeked a little bit into boost.build v2, but the only reference i could
find for mingw was in a comment.

i decided to fall back to gcc on linux (a more popular, and hopefully
better tested, platform).  i got the boost.python library and the example
python modules to build, but the modules had the "lib" prefix which caused
errors on import (as the modules' init functions did not include the lib).

i thought to try the daily tarball.  boost.python, examples, and tests
built and executed after i applied the attached patch to Jamfile.v2.

i've also attached my changes to boost-build.jam to facilitate using v2
while still allowing v1, modeled after the top-level boost-build.jam.

my user-config.jam is attached as it took me 30 minutes to an hour of
searching and reading until i had constructed it.  hopefully it'll save
somebody from the same struggle.  i read the boost.build v2 documentation,
but it was so abstract and general purpose that it didn't help me.  i
finally found http://zigzag.cs.msu.su/boost.build/wiki/BoostRegressionsV2
which is very concrete with examples, but initially i wasn't sure how
applicable it was because it's for "boost regression testing".

anyways, i'll look at boost.python on mingw sometime this week, but wanted
to feed back my patch for Jamfile.v2 ("release early, release often").

again, thanks for boost (python, build, etc).

ps i'm posting this to c++-sig as this email is specific to boost.python (i
only previously posted to boost-users because my patch resolved a problem
previously discussed there) and i'm too lazy to subscribe to boost devel.
