Multiple typemap files with MakeMaker

Post #1 of 3 (519 views)

A co-worker just came and asked me how to specify that you want to use
multiple typemap files in an extension (he wanted to use the default plus
Tk's typemap file).

I dug around in MakeMaker.pm and found you can do this by simply rewriting
the MY::tool_xsubpp subroutine, but I also noticed that the code in that
routine seems incorrect.

The pod file for xsubpp seems to say you need to say:

-typemap file1 -typemap file2 -typemap file3

However, the code in MakeMaker (4.16) says:

my(@tmargs) = map("-typemap $_", @tmdeps);
"...
XSUBPPARGS = @tmargs
";

Thus if @tmdeps ever contains three values, then won't the args to xsubpp be:

-typemap file1 file2 file3

I can't seem to find the map function defined anywhere....

Can someone who knows more than me help explain this to me?

Thanks,
Jeff

Dean sent me a patch recently that fixes that. Current MM supports
multiple typemaps. Grab it from CPAN/authors/id/ANDK.

That's in the regular perlfunc manpage:)

No. The code is fine.
