[CastXML] Runtime error while finding element_type with containers of pointers

[Ankit Deepak]

Hello all,

I have started working on CastXML recently. I am trying to modify pybindgen
[1] to work with CastXML and latest versions of pygccxml. "__find_xxx_type"
of "container_traits" throws Runtime Error when it encounters std
containers having pointers as elements, it works fine with other
containers. The traceback looks like:

Traceback (most recent call last):
  File
"/home/ankit/Videos/bake/source/ns-3-dev/bindings/python/ns3modulescan-modular.py",
line 284, in <module>

sys.argv[4], sys.argv[5])

line 484, in __find_xxx_type
RuntimeError: Unable to find out list '::std::list<ns3::ArpCache::Entry *,
std::allocator<ns3::ArpCache::Entry *> >' key\value type.

Similarly, it fails with

RuntimeError: Unable to find out map '::std::map<std::basic_string<char>,
ns3::LogComponent *, std::less<std::basic_string<char> >,
std::allocator<std::pair<const std::basic_string<char>, ns3::LogComponent
*> > >' key\value type.

Am I missing something regarding such containers? Please advise.

I am sorry if I was unable to explain everything clearly.
