Yep, that was the issue. Plugin now generating. Thanks!

Now to realize a plugin implementation..., to speed up my RS code.

Hi Robert,

According to your stack trace, the argument of #declareCVarsIn: is not a CCodeGenerator but the symbol #cg. And that is what causes the problem. I think you may not be running the right code to generate the plugin sources.

I got past this by removing the call to super>>#declareCVarsIn: from RSFECPlugin class>>#declareCVarsIn:, just like DESPlugin & DSAPlugin. SHA2Plugin still calls the super method, which does not walkback.

Hi,

I am getting a walkback when generating new external plugins: RSErasurePlugin and RSFECPlugin. The culprit seems to be a super call to InterpreterPlugin class>>#declareCVarsIn:, called from RSErasurePlugin class>>declareCVarsIn:. I snipped the stack to pertinent frames. Thx!
