Re: ?python::boost throw issues? Answer

Here is what is currently causing the problem:

% g++ abc_sl.o -shared -fpic -L../apikit/lib/hppa8000 -lAbc
-lboost_python -lcl -ldld -lm -o abc_sl.sl

% g++ -shared -fpic -L../apikit/lib/hppa8000 -lAbc -lboost_python -lcl
-ldld -lm -o abc_sl.sl abc_sl.o 

Question: Which one is "correct"?

Well to me the second version looks more Unixee as Unix commands like
chmod allow one to put one or more files at the end.

They both produce shared libraries whose byte counts are
588552
and
656156
respectively.

BUT, only the first ones throws an exception that is caught in the
Python environment as a normal exception. The second version causes a
segment fault. 

(g++ 2.95.3 on HPUX 10.20 with Python 2.1b2  All files compiled with
-g and NO -O optimization flags.)
