Identifying types in the types table.

[Guillaume Yziquel-4]

Hello.

I'm still wrapping my C++ code into OCaml. I'm having an issue with
SWIGTYPES. I was getting this

> Exception: Failure "No appropriate conversion found.".

when executing code from the OCaml toploop. The issue seems to be that
types are handled dynamically, and that the std__basic_stringT_char_t is
declared to be different that the string type. Which it really ought not
to be.

The types table is below. How do I tell swig that these two type are in
fact the same?

All the best,

OK. Solved. I removed using namespace std to avoid confusions...

But know that I've added %include std_list.i, I get the following error:

> yziquel@seldon:~/svn/main/libmorfo-ocaml$ make 2>& 1 | grep error
> /usr/include/c++/4.3/bits/stl_list.h:1394: error: no match for ‘operator==’ in ‘__i1.std::_List_const_iterator<_Tp>::operator* [with _Tp = analysis]() == __i2.std::_List_const_iterator<_Tp>::operator* [with _Tp = analysis]()’

The freeling.i file I'm using follows below.

What does this error mean?

All the best,

Guillaume Yziquel.
