Re: [Boost-build] controlling suffix of a dynamic library file in BBv2

Hi Phillip,

using PYTHON_EXTENSION was an excellent suggestion. Thank you. I don't know how 
I could overlook this variable.

I've added

type.set-generated-target-suffix PYTHON_EXTENSION : <os>HPUX : sl ;

line to python.jam and verified, that the boost python library tests succeed 
with Python 2.4.3 which does not support .so suffix. I'm running full 1.34 tests 
now and if everything goes well, will submit a patch.

Thanks again for the excellent suggestion.

Boris
