[C++-sig] Another BPLV2 newbie...

I must rebuild Boost.Python with that parameter I take it. (Just setting
it in my code didn't work. Though it did slow down a simple example from
5 seconds compile time to 10 seconds... so it did *something* ;) I will
try this "tomorrow" (after sleep). (My timezone is "+0200"). For now I
have commented the .def for the one horrible 17 parameter method...

Interesting thing I did notice, even with this commented, I need to pass
gcc a -ftemplate-depth-35 parameter (I'm using GCC 2.95.4.
-ftemplate-depth-34 doesn't work.) I'll do some "trimming" of my code
later to find out exactly what causes this to be required...

That's what it was, yes, thanks.

I ran make in the tools/build/jam_src directory, then I ran
bin.linuxx86/bjam install - this installed a "jam" named binary only,
though it is identical to the "bjam" also in that dir. I realise "bjam"
is to distinguish between boost's jam and the original - I suggest the
tools/build/jam_src/Jamfile be adjusted to install a "bjam"-named binary
by default then instead?

One last thing I will get back to investigating later:

>>> import test_module
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ImportError: /home/hugo/Programming/boost/libs/python/bin/libbpl.so/gcc/release/inlining-on/runtime-link-dynamic/shared-linkable-true/libbpl.so.1.29.0: undefined symbol: PyType_GenericAlloc

Anyone have a tip to lessen the amount of time I'll spend scratching my
head?

Thanks!
