Library dependencies not respecting platforms

[ricardojlrufino]

Configuration

Operating system: Ubuntu Linux 64

PlatformIO Version: PlatformIO, version 3.1.0

Description of problem

I have a library that has dependencies on other libraries and some are specific per platform.

Previously I was managing the dependencies through a dependencies.h file in my library. The problem is that the user has to be editing the library files for each sketch, that's not cool.

I'm upgrading to platformio, and I am struggling to solve this problem, it seems to be a bug.

LIB: https://github.com/OpenDevice/opendevice-lib-arduino/tree/0.1.4

  "dependencies": [
    {"name": "PubSubClient", "version": ">=2.6"},
    {"name": "EnableInterrupt", "version":  ">=0.9.5", "platforms" : "atmelavr"},
    {"name": "MFRC522", "version":  ">=1.1.8"},
    {"name": "Bridge", "version":  ">=1.6.1", "platforms" : "atmelavr"},
    {"name": "Ethernet", "version":  ">=1.1.2", "platforms" : "atmelavr"},
    {"name": "EEPROM", "version":  ">=2.0"},
    {"name": "SPI", "version":  ">=1.0"},
    {"name": "WiFi", "version":  ">=1.2.7", "platforms" : "atmelavr"},
    {"name": "ESP8266WiFi", "version":  ">=1.2.7", "platforms" : "espressif8266"}
  ],

Steps to Reproduce

Starting an example, I have two platforms set in my Skech: atmelavr / uno, espressif8266.
When I compile for UNO, throws an error that can not find the lib ESP8266WiFi that this being should only be "active" when compiling for the esp8266

Actual Results (ERROR)

pio run -e uno -vv

Expected Results

Compile "OpenDevice" using libraries with match the platform of active enviroment

If problems with PlatformIO Build System:

The content of platformio.ini:

[platformio]
env_default = uno

[common]
lib_deps = PubSubClient

[env:uno]
platform = atmelavr
board = uno
framework = arduino
lib_compat_mode = 2
lib_deps = ${common.lib_deps}
; enable auto-uploading
;targets = upload


[env:esp12e]
platform = espressif8266
board = esp12e
framework = arduino
lib_compat_mode = 2
lib_deps = ${common.lib_deps}

Source file to reproduce issue:

// I only use a blink and include:
#include <OpenDevice.h>

Additional info

On lib, i'm using: "build" : { "libLDFMode" : 0 }
On sketch: lib_compat_mode = 2

Thanks a lot for the great report! This is a bug and I've just fixed it. Please re-test with the http://docs.platformio.org/en/stable/installation.html#development-version

I found a problem with "EnableInterrupt" library

• http://platformio.org/lib/show/311/EnableInterrupt/manifest

This library doesn't has platforms field and PIO Build System can not check for platform compatibility. There are 2 options:

1. Male PR to https://github.com/GreyGnome/EnableInterrupt and specify platforms field.
2. Replace {"name": "EnableInterrupt", "version": ">=0.9.5", "platforms" : "atmelavr"}, with {"name": "EnableInterrupt", "version": ">=0.9.5"},

WoW... Thanks for the quick fix...
It's working now finally .... was for more than four hours trying to solve ...

One question: Why dependencies are not automatically downloaded?

And a small problem: I think the verification platform is very narrow and some libraries are using the old name: "espressif

.piolibdeps/MFRC522_ID63/library.json

{
  "name": "MFRC522",
  "frameworks": "arduino",
  "platforms": ["atmelavr", "ststm32", "teensy", "espressif"]
}

Running

pio run -e esp12e -v

I got:

Why dependencies are not automatically downloaded?

It should work. If library is already installed, then PIO will not re-check "dependencies". Try to isntall

pio lib -g install https://github.com/OpenDevice/opendevice-lib-arduino/archive/0.1.4.zip

I think the verification platform is very narrow and some libraries are using the old name: "espressif

I'll think on it. Maybe, will add some hook for that.

I think it's because I'm using the lib directly without installing. Thanks
