"warning duplicate class registration for S"

August 14, 2009 | 9:02 pm

I’m just learning how to make my own externals. I got my first one to build successfully, but when I try to instantiate it in Max, I get four error messages in the Max window saying:
"warning duplicate class registration for S"

So I followed the example in the "anatomy of a max patch" section of the documentation exactly, and the same exact thing happens.

I’m using Xcode 3.1.2 and I followed the directions in the c74 tutorials for getting an object started in Xcode 2.2, assuming it wouldn’t be too much different.

can anyone help me out?

You must be calling your class "s", but a class of that name already exists (the send object). What are you passing into the class_new function as your classname?

class_new("myobject", …)

It should be the name of your external.
