Hi all,
I have a module which references symbols defined in external libraries. I'd
like to create a list of functions referenced by the module (e.g. module A
references function B). How can I do this without including data
references? nm gives me a list of all undefined references but AFAIK always
groups text and data references together. Thanks for any advice.
Thanks,
Shaun

The simple answer is you can't. On most targets undefined references
are not typed. You need the definitions to be able to differentiate
between functions and data.
