I'm working through Garfinkel and Mahoney's MathPaper example (see the
book). I can build the Evaluator backend, and have tested it from the
console. I've built the front end, and linked the two according to
instructions in the book (I think/hope). Tracing PaperController, it
seems lastLine (the expression) is encoded as NSData and is sent to
Evaluator (no runtime errors, etc). However I never get an answer back
from Evaluator. Since Evaluator appears to work correctly, it seems to
me that the data never reaches Evaluator, however with little C
experience I'm not sure how to approach debugging this.
Any clues? For those without the book, I'm happy to supply code
fragments.
Mark
