Compiling Failed.

[teezzan]

Hello,

I have had no success compiling the source code. I followed the instruction given in the README file. After configuring using the menuconfig interface, I ran make flash after which it will begin to compile but run into a particular error. The complete compilation log is as follows.

 $make flash

Been a while since I touched the code, seems it doesn’t work anymore with the latest esp-idf. Either use an older version or fix the errors, pull requests accepted.
