Calling an XSUB method from Catalyst

JNW has asked for the wisdom of the Perl Monks concerning the following question:

Hello Monks,

I have written an XSUB method (and all of the bits around it) which works well when called from perl (as long as the path is specified using -I)

The reason that I wrote it was to use its functionality from catalyst. When I call it from catalyst, I'm informed that I have called an ``Undefined subroutine''. I am using exactly the same use and calling statement in both the test script and the Catalyst Controller.

Have I missed something obvious?
I read that Catalyst is pure-perl - does a pure perl implementation preclude me from calling XSUB?
Is there a particular include that I am missing in the Catalyst install?
Something else?

Thanks for your time!

It's probably a perms issue. How did you install it? Where is it located? Can you build a module out of it to let ExtUtils::MakeMaker (or M::B, or M::I, or whatever) install it? UPDATE: The fact remains that Catalyst is just a bunch of perl modules, therefore, what works for your short script works for Catalyst. It's either a relative path issue or perms. There just aren't many other choices. There are obscure things like confusingly persistent scopes in mod_perl, but I doubt that's what's happening here. -Paul	[reply]

Thank you for your reply I'm not sure that it is a permissions issue. I'll be delighted if I am wrong though! I installed it using the Makefile rule `make install_site` having run `perl Makefile.PL`. I did adjust the output directories to exist in a known place in an SVN repository off my home directory - this was deliberate as the people working on this do not all have root access on their respective machines. The location is correctly given to perl in the `-I` argument. Removing the `-I` prevents the code from running at all, where as including it satisfies the interpreter, until the function is called. The permissions on the `.so` are `555`. and the `.ix` and `.bs` are `444`. I'm not sure what the purpose of the .ix and .bs are though. Everything else is a mix of `444` and `644` for the files; all of the directories are `755`. Everything is owned by `me:me` all the way up and down the directory tree (until I get to `/home`). Thank you again for your time	[reply] [d/l] [select]

So the use statement in the catalyst program succeeds? Then its your code. You did `somethingcatalyst->foo` but you wanted `myfooxswbar->foo`.	[reply] [d/l] [select]
