Re: [Swig-devel] What is swig::LANGUAGE_OBJ?

[Mark G. <ma...@go...>]

Hello,

When I was running my Python 3 test suite, I found many compiling errors 
like this:

li_std_set_wrap.cxx:9363: error: ?LANGUAGE_OBJ? is not a member of ?swig?

I searched all the SWIG's codebase and only found some words in 
Examples/test-suite/li_std_map.i saying:

...
  * @brief  a test of map containers.
  *         Languages should define swig::LANGUAGE_OBJ to be
  *         an entity of their native pointer type which can be
  *         included in a STL container.
  *
  *         For example:
  *                swig::LANGUAGE_OBJ  is  GC_VALUE in Ruby
  *                swig::LANGUAGE_OBJ  is  PyObject_ptr in python
...

But I can't find the LANGUAGE_OBJ defined anywhere. Could you tell me 
how to define it?

Thank you!

Hello Haoyu Bai,
I seem to remember it appearing SWIG about a year or so ago. At the time I had issues with it and raised them. In the end the Lua code fixed it with the following stub.
#ifdef __cplusplus
%ignore swig::LANGUAGE_OBJ;
%{
namespace swig {
typedef struct{} LANGUAGE_OBJ;
}
%}
#endif // __cplusplus

Hope this helps.
Regards,
Mark
