[sword-devel] Python binding issue: non-default constructor in class without a constructor

[Ben Morgan]

Hmmm...
The problem occurs because SWIG cannot handle nested classes properly, so I
have to have an outer class to do it. This means that swig needs to see one
version so it will generate the correct bindings, and the c++ compiler needs
to see what really is happening.

The setup.py script currently defines the SWIG macro, meaning that the c++
compiler is looking at the version that swig looks at. This shouldn't be
happening.

These two solutions should work:
1. Remove this line in setup.py (Note: I haven't tried this...)

 define_macros=[('SWIG',1)])],


2. Or even better, build it with configure (from the package directory)
./configure
make pythonswig
make python_make
cd python
python setup.py install

Hope this helps.

God Bless,
Ben
