This problem is driving me crazy. I have some functions written in C++
with a C wrapper that I need to make available from Perl. I wrote a swig
interface for them, and got it to compile and run. But OpenBabel can't
seem to initialize itself.
./test/swig_wrapper_test.pl

Looking at the code (ops/loader.cpp) it seems like it can't find its .txt
files. But other programs, such as obabel and C++ programs that I compiled
without swig, all work fine. LD_LIBRARY_PATH is correct, and defining
BABEL_DATADIR doesn't make any difference.
I'm wondering if it's related to C versus C++ internal initialization ...
like maybe the C++ initialization code isn't being called. I used g++ for
the "CC" and "LD" in Makefile.PL, but it made no difference.
Any ideas? Guesses?
Thanks,
Craig
