Thanks sherm for replying.

CBPerl is a singleton, so it's better to use the class method to  
access the shared instance:

        CBPerl *perl = [CBPerl sharedPerl];

That doesn't work here. Get a nil pointer returned.

Should be:

        id perlO = [[NSClassFromString(@"SomePerl") alloc] init];

Note that perlO is typed as "id". That's necessary because the  
compiler doesn't know about the SomePerl class at compile time. The  
call to NSClassFromString() is needed for the same reason.

That either returns a nil pointer. Where does the ObjC runtime system  
look for the SomePerl.pm file.
I placed it in some locations, so it should be found by whom ever. ;)
How does this work in general, maybe I can figure out where the  
problem is.


SomePerl.pm should look like this:

    package SomePerl;

    use CamelBones qw(:All);

    use strict;
    use warnings;

    class SomePerl {
        'super' => 'NSObject',
        'properties' => [ 'foo', 'bar', 'baz' ],
    };

    sub init : Selector(init) ReturnType(@) {
        my ($self) = @_;
        $self = $self->SUPER::init();

        # Do other initialization

        return $self;
    }


Ok, done that.
