Building in 2021 for SDK 8.4.0 #37

Open ssshake opened 2 years ago

ssshake commented 2 years ago

I just learned of this project and I'm excited to build it and play around with it but the build instructions are not clear.

Where I'm at at this point is the user.cfg by default specifies GCC 4.8.5 but I have no idea where to get that. ESP's documentation links to a much newer version of 8.4.0.

Building against 8.4.0 produces this output. I'm assuming there are just breaking changed between 4 major versions of the SDK.

I could build this with 4.8.5 if only I knew where to find it, google isn't being friendly today.
