make: *** No rule to make target '//Makefile'. Stop.

Postby abi.rulezz@gmail.com » Sun Sep 15, 2019 7:30 am

Environment
Development Kit: ESP32-DevKitC
Kit version (for WroverKit/PicoKit/DevKitC): v1
Module or chip used: ESP32-WROOM-32
IDF version : v3.3
Build System: Make
Compiler version : (crosstool-NG crosstool-ng-1.22.0-80-g6c4433a5) 5.2.0
Operating System: Windows
Power Supply: USB

Problem Description
When an example ulp project(esp-idf-solutions repository) is built it fails by saying "make: *** No rule to make target '//Makefile'. Stop." However, I have installed and added the ulp toolchain in path. The ulp examples in the main esp-idf repository builds and I can flash successfully. The ulp examples of esp-idf-solutions do not work.

Expected Behavior
Expected Behavior is that Build should be successful.

Actual Behavior
Gives build error: make: *** No rule to make target '//Makefile'. Stop.
