Platformio-core: #includes in included files are not recognized

[jadedanemone]

Configuration

Operating system: Mac 10.11.4

PlatformIO Version (platformio --version): PlatformIO, version 2.9.1

Description of problem

Certain #includes in #includes are not recognized.

Steps to Reproduce

1. With the board set to Adafruit HUZZAH ESP8266
2. Duplicate the "BasicOTA.ino" example from https://github.com/esp8266/Arduino/tree/master/libraries/ArduinoOTA/examples/BasicOTA
3. Remove the #include <ESP8266mDNS.h> from BasicOTA.ino.
   

   Actual Results

.pioenvs/huzzah/ArduinoOTA/ArduinoOTA.cpp:21:25: fatal error: ESP8266mDNS.h: No such file or directory
#include <ESP8266mDNS.h>
^
compilation terminated.

Expected Results

Successful compilation.

If problems with PlatformIO Build System:

The content of platformio.ini:

[env:huzzah]
platform = espressif
framework = arduino
board = huzzah

Source file to reproduce issue:

#include <ESP8266WiFi.h>
#include <WiFiUdp.h>
#include <ArduinoOTA.h>

const char* ssid = "..........";
const char* password = "..........";

void setup() {
  Serial.begin(115200);
  Serial.println("Booting");
  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid, password);
  while (WiFi.waitForConnectResult() != WL_CONNECTED) {
    Serial.println("Connection Failed! Rebooting...");
    delay(5000);
    ESP.restart();
  }

  // Port defaults to 8266
  // ArduinoOTA.setPort(8266);

  // Hostname defaults to esp8266-[ChipID]
  // ArduinoOTA.setHostname("myesp8266");

  // No authentication by default
  // ArduinoOTA.setPassword((const char *)"123");

  ArduinoOTA.onStart([]() {
    Serial.println("Start");
  });
  ArduinoOTA.onEnd([]() {
    Serial.println("\nEnd");
  });
  ArduinoOTA.onProgress([](unsigned int progress, unsigned int total) {
    Serial.printf("Progress: %u%%\r", (progress / (total / 100)));
  });
  ArduinoOTA.onError([](ota_error_t error) {
    Serial.printf("Error[%u]: ", error);
    if (error == OTA_AUTH_ERROR) Serial.println("Auth Failed");
    else if (error == OTA_BEGIN_ERROR) Serial.println("Begin Failed");
    else if (error == OTA_CONNECT_ERROR) Serial.println("Connect Failed");
    else if (error == OTA_RECEIVE_ERROR) Serial.println("Receive Failed");
    else if (error == OTA_END_ERROR) Serial.println("End Failed");
  });
  ArduinoOTA.begin();
  Serial.println("Ready");
  Serial.print("IP address: ");
  Serial.println(WiFi.localIP());
}

void loop() {
  ArduinoOTA.handle();
}

Additional info

This seems to be #189 and #195 again.
Note: I have provided a generic way to reproduce the problem, and will work around it in my current code. However, this is not the desired or intended behavior, so, bug report...

Deep scanning for dependent libraries is turned off by default. See lib_dfcyclic.

[ivankravets]

The simple way is to add #include <ESP8266mDNS.h> to your main source file.

[jadedanemone]

So, what you are saying is "this is the intended behavior"? I'll work around that if I need to. What is the drawback to turning lib_dfcyclic on by default?

[ivankravets]

What is the drawback to turning lib_dfcyclic on by default?

We had this option enabled before by default. However, we received a few issues where that doesn't work properly. In this case, we propose developers 2 options:

1. They manually specify in source files (src dir) required libraries
2. They have an ability to enable deep search for dependent libraries via the special option in platformio.ini.

I'm working on PlatformIO 3.0 where Build System for libraries will be rewritten from the scratch. Maybe, I'll find better solution.

I'm stuck on this problem. I've tried putting lib_ldf_mode = deep in the ini file and putting #include <EEPROM.h> in every file in my project (!). I'm going to have to put the library code in my main file until this is fixed.

@mark-hahn could you provide a project to reproduce this issue?

[mark-hahn]

Sure, Is there a way I can send it only to you instead of making it
public? It's semi-private.

@mark-hahn Please send to [email protected], I'll not share your project.

[mark-hahn]

I reverted back to the time I had the problem and of course I can't recreate the problem. I'm pretty sure what I reported in the OP was accurate at the time. If I get back in that state I'll zip up the entire project folder and come back here.

Anyway, sorry for the trouble.

[roboflank]

Am also having the same issue.
