Can't compile in vscode using platformio

shaw.isabel.krystal · October 2, 2021, 6:26pm

Hello,
For the life of me, I can not get my project to compile…I select my m5core 2, set the com port ect…All plugins are good (no red lines) and this sketch just built in arduino ide no problem. However I really want to use vscode.

The error:
collect2.exe: error: ld returned 1 exit status
*** [.pio\build\m5stack-core2\firmware.elf] Error 1
================================== [FAILED] Took 61.98 seconds ===
I am unsure what to do at this stage. Any advice would be greatly appreciated.

The real error would have been above that line. That just says “Could not link :(”.

Please post your full platformio.ini and code that you’re using.

shaw.isabel.krystal · October 2, 2021, 11:02pm

Here is the ini file.
[env:m5stack-core2]
platform = espressif32
board = m5stack-core2

Here is the output of the terminal NOTE: There were no red entries in the terminal except the last line about firmware.elf

The terminal process “C:\Users\Administrator.MYTDS.platformio\penv\Scripts\platformio.exe ‘run’” terminated with exit code: 1.

I would post my script but the main ino file is over 4k lines long lol. but if you want snippets please let me know.

maxgerhardt · October 2, 2021, 11:11pm

This says there is no loop() and setup() functions in the project.

What is the content of the src\main.cpp file?

If you have multiple projects in your workspace, did you correctly switch to it with the project environment switcher?

shaw.isabel.krystal · October 2, 2021, 11:14pm

There is certianly loop and setup in the project (how could arduino ide compile without?)

Looking in the src folder there is no main.cpp file at all.

maxgerhardt · October 2, 2021, 11:15pm

You as the programmer must implement the setup() and loop() function in your source code.

If there is no source code in src/, where is the code?

shaw.isabel.krystal · October 2, 2021, 11:15pm

Sorre posted the wrong ini file

[env:m5stack-core2]
platform = espressif32
board = m5stack-core2
framework = arduino
lib_extra_dirs = ~/Documents/Arduino/libraries

shaw.isabel.krystal · October 2, 2021, 11:16pm

The code is there with the name n512.ino, but there is no cpp file with that name. There never has been for some reason…

shaw.isabel.krystal · October 2, 2021, 11:18pm

Setup:

void setup() {

  Serial.begin(115200);

 LEDS.addLeds<NEOPIXEL, PIN>(leds, NUM_LEDS);

  

    // initialize the M5Stack object

    M5.begin(true, true, true, true, kMBusModeOutput);

    #ifdef ARDUINO_M5STACK_Core2

      M5.Axp.SetSpkEnable(true);

//      InitI2SSpeakOrMic(MODE_SPK);

    #else

      M5.Power.begin();

    #endif

FastLED.addLeds<NEOPIXEL, PIN>(leds, NUM_LEDS);

  pinMode(2,INPUT_PULLUP);  // internal pull-up resistor

    // prevent button A "ghost" random presses on older versions

    Wire.begin();

    SPIFFS.begin();

    SD.begin();

    // M5.Speaker.mute();
(additional code goes on)


Loop:
oid loop() {

  if (!playing) {

    mainLoop();

    longMainLoop += 1;

    if (!printed && playedOnce) {

      /*String mainLoopString = "xx";

        String wavLoopString = "xx";

        mainLoopString = "mainLoop:" + longMainLoop;

        wavLoopString = "wavLoop:" + longWaveLoop;*/

      Serial.println(longMainLoop);

      Serial.println(longWaveLoop);

      printed = true;

    }

    delay(40);

  }

  else

  {

    finalizeWAVInstance();

    longWaveLoop += 1;

    //Serial.println("mainLoop:" + longWaveLoop);

  }

maxgerhardt · October 2, 2021, 11:20pm

An .ino file is okay, but it would be better if it was a .cpp file.

Where is that n512.ino file located? In src/?

shaw.isabel.krystal · October 2, 2021, 11:20pm

yes. it is located in C:\Users\Administrator.MYTDS\Documents\PlatformIO\Projects\211002-155957-m5stack-core2\src

maxgerhardt · October 2, 2021, 11:21pm

Use the project tasks “Clean”, then “Build”. Post the full output of the “Build” task. Use markdown code formatting to format it correctly with three backticks.

shaw.isabel.krystal · October 2, 2021, 11:27pm

Well that is interesting. I had no errors except the firmware.elf, after i cleaned it i now have a bunch of errors…

…there are two .ino files in the src/ folder, is this wanted? They’re trying to override the global setup() and loop() function each.

shaw.isabel.krystal · October 2, 2021, 11:31pm

Yes there is an LED.ino file, I have a bunch of different effects used for different things and i looked around and people suggested using an ino file to hold them instead of having a huge main ino file.

shaw.isabel.krystal · October 2, 2021, 11:33pm

wait a minute. the led file wasnt supposed to have setup or loop. i just removed those lines…i just removed the ino file, but still have problems now

Remove (or move) all src/*.ino files and place a known-good Blink.cpp (platform-espressif32/Blink.cpp at develop · platformio/platform-espressif32 · GitHub) in the src/ directory.

Does it compile? If yes, the problem is the code.

shaw.isabel.krystal · October 2, 2021, 11:37pm

No, it did not compile…

maxgerhardt · October 2, 2021, 11:50pm

Okay, but because LED_BUILTIN wasn’t defined, the examples does that through the platformio.ini

github.com

platformio/platform-espressif32/blob/1e0f14730b041a337efd9f37d915851d703ee041/examples/arduino-blink/platformio.ini#L15-L17


      
          build_flags =
          	; https://docs.espressif.com/projects/esp-idf/en/latest/get-started/get-started-wrover-kit.html#rgb-led
          	-D LED_BUILTIN=2

Add that and it should compile.

You should avoid adding all your Arduino libraries. Do library management through the intended lib_deps, e.g.,

lib_deps =
     m5stack/M5Stack @ ^0.3.6

(PlatformIO Registry)

shaw.isabel.krystal · October 2, 2021, 11:53pm

Yes after adding that it did compile correctly. Does that mean my code is messed up? or am i just missing a build flag somewhere?
