[Swig-devel] BUG REPORT]Does anyone know how to covert ruby bignum to C++ long?

[Han, K. <Kim...@am...>]

Hi, all

 

I am trying to generate Ruby module from SWIG.

I have several methods receiving long type as a parameter. When I first
just try to pass a big num directly from Ruby to Swig, SWIG complained
"Big num is too large to convert to long."

 

So I added a typemap definition as below.

 

%typemap (in) long {

 

  $1 = (double) NUM2DBL($input);

}

 

After that addition, SWIG stop complaining but the value was not passed
or retrieved correctly.

 

Am I using a long methods for the conversion or is it a bug of NUM2DBL?

 

Or is it a bug of NUM2DBL?
