[solved] building in MINGW32 / make TARGET=app fails with 'no rule to make target'



  • Submitted issue @ https://github.com/pycom/pycom-micropython-sigfox/issues/220

    Hello. I am trying to build firmware from source and make TARGET=app does not compile with following error. Hopefully it's something silly due to my unfamiliarity with the environment.

    ...
    CC ../py/../extmod/uos_dupterm.c
    CC ../py/../lib/embed/abort_.c
    CC ../py/../lib/utils/printf.c
    make: *** No rule to make target 'build/WIPY/release/frozen_mpy/frozen/Base/_boot.mpy', needed by 'build/WIPY/release/frozen_mpy.c'.  Stop.
    

    I have followed these instructions to setup the build environment on Windows 10:

    1. https://docs.espressif.com/projects/esp-idf/en/latest/get-started/
      I am able to build vanilla esp-idf hello_world example.
    2. https://github.com/pycom/pycom-micropython-sigfox
      I did not download the listed xtensa gcc compiler since one already exists from step #1.
    xtensa-esp32-elf-gcc.exe (crosstool-NG crosstool-ng-1.22.0-80-g6c4433a5) 5.2.0
    
    $ printenv PATH

    1. https://github.com/pycom/pycom-esp-idf
    $ printenv IDF_PATH
    D:/msys32/home/chris/esp/pycom-esp-idf
    
    1. build
    cd mpy-cross && make clean && make && cd ..
    cd esp32
    make clean
    make TARGET=boot
    make TARGET=app
    make flash
    

    output of mpy-cross:
