building Python extension modules - crash on import

["Peter Bienstman" <Peter dot Bienstman at rug dot ac dot be>]

Hi,

I'm trying to build a simple C++ Python extension module under the latest
cygwin.

The module's name is 'convert'. After compiling convert.o as usual, I
created a convert.def containing

EXPORTS
	initconvert

I then used this command to build the dll:

dllwrap --dllname convert.dll --driver-name=g++ --def convert.def \
	-o convert.dll -s --entry _DllMain@12 \
	convert.o $(BOOST_LIB)/libboost_python.a \
	/usr/bin/libpython2.1.dll

This creates the dll without problems, but when I try to use it, I get a
segmentation fault:

>>>from convert import *
	0 [main] python 406 open_stackdumpfile: Dumping stack trace to
python2.1.exe.stackdump
Segmentation fault (core dumped)

Under Unix, I got everything working without problems.

Any insights?

Thanks,

Peter
