[Mono-list] Re: [DotGNU]Swig and C# (was: Strategy for dealing with C++ )

[James Michael DuPont]

I downloaded the example, 
> http://www.geotab.ca/Old/SwigCLRNeilCawse10dec02.zip

I have done a quick test of the generation, using the cvs version of
redland.i.

http://introspector.sourceforge.net/dotgnu/redland.zip

Very impressive for a first start. It looks just like code from XSharp,

Here is a method i have been fighting with with the php4 swig :
int librdf_serializer_serialize_model(librdf_serializer* serializer,
FILE *handle, librdf_uri* base_uri, librdf_model* model);

The generated code is this :
[DllImport("Redland")]
  public static extern int librdf_serializer_serialize_model(int jarg1,
int jarg2, int jarg3, int jarg4);

I dont have time at work to look into this, 
but it looks like all the type information got killled.

I will try it out with pnet at home and report any success, or what I
had to change to get this running. 


If all works out, we can use swig for creating lots of C# wrappers. 

Thanks for the tips, I will be looking into this in detail.
