Frank Meier commented on BIT-528:
---------------------------------

When trying to compile current version from git with python 3 I get this error:

[  9%] Building CXX object aux/broker/bindings/python/CMakeFiles/_pybroker.dir/pybrokerPYTHON_wrap.cxx.o
bro/build/aux/broker/bindings/python/pybrokerPYTHON_wrap.cxx: In function ‘PyObject* _wrap_frontend_request__SWIG_1(PyObject*, PyObject*)’:
bro/build/aux/broker/bindings/python/pybrokerPYTHON_wrap.cxx:39324:40: error: ‘PyInt_AsSsize_t’ was not declared in this scope

To solve this one could use the following define in pybroker.i :

#if PY_MAJOR_VERSION >= 3
#define PyInt_AsSsize_t PyLong_AsSsize_t
#endif

There are still a lot of warnings about uninitialized argv[0], but it seems to work. 
Perhaps this could better be solved using Swig, but I didn't find out how (-py3 does not help).
