[Swig-user] bug wrapping template

[Marco C. <mar...@gm...>]

I think I found a bug. Consider the following example module called mytest:

%module mytest
%inline %{

template<class T> struct Seq;

template<class E>
struct Expr
{
  Expr() {}
  void method1() { }
};

template<class E>
struct Expr<Seq<E> >
{
  Expr() {}
  void method2() { }
};

%}

%template(IntExpr) Expr<int>;
%template(IntSeqExpr) Expr<Seq<int> >;

Compiling gives:

swig -o mytest_wrap.cpp -c++ -python mytest.i 
ok.

g++ -o mytest_wrap.os -c -g3 -O0 -Wall -fPIC -I/usr/include/python2.7 
mytest_wrap.cpp 

errors:
mytest_wrap.cpp: In function ‘PyObject* _wrap_IntSeqExpr_method1(PyObject*, 
PyObject*)’:
mytest_wrap.cpp:2896:11: error: ‘struct Expr<Seq<int> >’ has no member named 
‘method1’

It seems that SWIG is not finding the proper template specialization. I'm 
attaching the source mytest.i.

Thanks!
Marco
