Hi all,
I'm trying to get OpenSG's python-bindings to work on Windows (and
contruibuting that back to the project), and trying to track down an
exception that get's thrown when running it's gen_bindings.py. (see
attached log.txt for output)
The source for gen_bindings.py is here, for reference:
https://realityforge.vrsource.org/trac/pyopensg/browser/branches/trunk_update/src/gen_bindings.py
From what I can see, the exception is thrown, as can be seen, in
read_gccxml_file in pygccxml/parser/source_reader.py. The generation of
the temp xml file (self.create_xml_file( ffname )) creates an empty
file, which then gets a syntax error when read back.
As I'm rather new to py++ (being old on c++ and average on python) I
don't really know where to look when hunting for this bug.
The PyOpenSG-devs have only used linux, and have maybe seen this before,
earlier, but can't recall what and when. They also have used a earlier
py++-version, but I'm using 1.0. I might be shooting myself in the foot
with that, but I hope not.
All help gratefully recieved. :)
Cheers,
/Marcus
