[Swig-user] Preprocessor problem with __LINE__

[Camille G. <k10...@wa...>]

Hello,

I'm using SWIG Preprocessor for writing wrapper code, and I didn't manage to 
get an unique identifier using __LINE__.

I tried the following :

>#define CAT_HELP(a,b) a##b
>#define CAT(a,b) CAT_HELP(a,b)
>#define UNIQUE_ID(a) CAT(a,__LINE__)
>UNIQUE_ID(foo)

And the only output I got was "foo__LINE__" (using both swig 1.3 and 2.0), 
whereas gcc gives "foo4".

Is there a known workaround ?

Thanks.
