help linking to python for dbus-python bindings

[Mark Mikofski]

updated again with autolaunch so that dbus works and dbus-python doesn't throw exceptions.

They are attached the this ticket:
https://bugs.freedesktop.org/show_bug.cgi?id=51580 

 
Thanks,

I attached instructions to install dbus-python on windows using mingw32 for review to this ticket:

Good to know. I've merged the wip-windows branch, so the next
dbus-python release will be similar to the snapshot you used.

Since you are now the world's foremost expert on compiling dbus-python
with mingw, would you mind writing a text file with instructions that
can go in the doc directory?

Instructions for compiling dbus-glib with mingw, or any patches you
needed to use, would also be very welcome.

I
 believe mixing compilers is normally only a problem if you share FILE
objects across library boundaries (which dbus, dbus-glib and dbus-python
don't), or if you use C++ (which those projects don't). So, you should
be OK here.

If nobody has told the bug tracker about them, then most likely no.

If people who have forked it want this to happen, the first step is to
put patches on the bug tracker for review. I do not periodically Google
for "dbus-python patch" or anything like that :-)

That might be a bug in Automake, yes. You should be able to work around
it by putting am_cv_python_pythondir on the configure command line,
something like:

    ./configure [... other stuff ...] \
        am_cv_python_pythondir='/opt/python/Lib/site-packages'

(If you set a *_cv_* variable - a "cached value" - like this, Autoconf
will trust what you say, and not do the automatic check it usually would.)

If it otherwise works, this warning is probably harmless. If there are
undefined symbols in the extension, I'd need to know which symbols they
are (preferably on a bug report).
