Pycopy requires special mbedTLS branch, see https://github.com/pfalcon/pycopy/blob/master/.travis.yml#L356 how to build esp32 with it.

I had this same problem as @pronyxhack and tried @pfalcon 's suggestion, but ran into different new problems. I'll try cleaning the directories and building again...

The problem was solved by compiling with the indicated instructions. Thank you pfalcon!

Glad that it worked. I'm not sure if this ticket should be left open, to help other folks, like @motjebben. Anyway, can be reopened if needed.

Otherwise, I'm committed to keep baremetal platforms from MicroPython building, but the main target of Pycopy is unix port, and the current direction is finishing it (then hopefully propagate changes back to baremetal ports). So, changes like are expected and necessary. Bottom line: if there's interest to run Pycopy on esp32, etc., then more people should participate in maintaining it. Otherwise, well, I just try to keep Travis from breaking for as long as I can ;-).

[motjebben]

I'm set, too, thanks! The next error I ran into appears to have to do with OS-X not liking deep linkages, and I'll work on that myself. Anyway, your pointer above was perfect! Be well!
