Basic globals/extern question

Hi

I've managed to go 12 years without ever needing globals but find that I need them for my current project (globally visible function pointers to a plugin) and am getting "reference to undefined _gPluginInterfaces" when I try to build.

I put all the globals in their own ".c" file and declare "extern PluginInterfaces *gPluginInterfaces;" at the top of all files that need to call the plugin functions but this doesn't seem to be cutting it.

Here's some of the error details I'm seeing

/<path>/PageUtils.o reference to undefined _gPluginInterfaces
/<path>/DocumentUtils.o reference to undefined _gPluginInterfaces

etc...

How do I reference these globals if not with "extern?"

Thanks

Ken
