Issue when compiling with ESP-ISF

[rezin8]

Jason, I'm trying to get this thing compiled and I'm hitting a brick wall... Here's what I'm getting. Did you run into anything like this?

Hi rezin8,

Sorry for the delay in answering this. I haven't seen this issue before. The undefined references are all functions defined in the dac-cosine component. So it would seem that somehow the build system isn't seeing that component or building it. Hopefully that helps.

Okay I looked into it a little and setup esp-idf from scratch on a new machine. It looks like since I last was playing with this esp-idf fully transitioned to CMake. I updated things so that they all build now. However this is completely untested other than it being able to compile now. It is giving me a few concerning errors I want to look at when I have more time

[rezin8]

No problem. I just wanted to play around with it. I have zero experience with esp-idf, I usually use Arduino IDE, so I'll mess around with what you have now and see what I can get working. Thanks.

Sounds good let me know if it builds for you and I will close this issue. If you run into other problems after it builds you can make a new issue
