Building Homie on Win10 fails but works on Linux (Ubuntu)

david · August 26, 2019, 4:25pm

I’m trying to build Homie-esp8266 on Windows. This worked before the upgrade to pio 4.0.
As a minimal setup, in a new project I have:
platformio.ini:

[env:nodemcuv2]
platform = espressif8266
board = nodemcuv2
framework = arduino
build_flags = -D PIO_FRAMEWORK_ARDUINO_LWIP2_LOW_MEMORY

lib_deps = https://github.com/homieiot/homie-esp8266.git

This is what I get on Windows:

> pio run -v
Processing nodemcuv2 (platform: espressif8266; board: nodemcuv2; framework: arduino; build_flags: -D PIO_FRAMEWORK_ARDUINO_LWIP2_LOW_MEMORY; lib_deps: https://github.com/homieiot/homie-esp8266.git; monitor_speed: 115200)
---------------------------------------------------------------------------------------------------------------------------------------------------------

I’ve truncated this, but it goes on to fail, unable to find AsyncMqttClient.h,
which is reasonable
I have tried exactly the same on Ubuntu, and it builds and links fine.
I’m using VS Code, Platformio Home 2.2.0 Core 4.0.2
Any help would be appreciated.

Did you install the dependency libraries in the global lib repository?

What happens when you do it under Windows, i.e. install all lib dependencies manually via the VSCode GUI?

The warning comes from here but I’m not sure which places are searched exactly…

              if not self.dependencies:
                  return
              for item in self.dependencies:
                  found = False
                  for lb in self.env.GetLibBuilders():
                      if item['name'] != lb.name:
                          continue
                      found = True
                      if lb not in self.depbuilders:
                          self.depend_recursive(lb)
                      break
          
                  if not found and self.verbose:
                      sys.stderr.write("Warning: Ignored `%s` dependency for `%s` "
                                       "library\n" % (item['name'], self.name))

I didn’t do any extra library installation on either Ubuntu or Windows

If I add the dependencies to platformio.ini on Windows, then it works.

lib_deps =
    https://github.com/marvinroger/homie-esp8266.git#develop
    ArduinoJson@^5.10.0
    AsyncMqttClient@^0.8.0
    Bounce2@^2.1.0
    ESP Async WebServer

I am using ‘Git for Windows’ which has known issue:

Some console programs, most notably non-MSYS2 Python, PHP, Node and OpenSSL, interact correctly with MinTTY only when called through winpty (e.g. the Python console needs to be started as winpty python instead of just python ).

Could this upset the Library Dependency Checker? Just clutching here, don’t know what I’m talking about.
