Cannot compile the example sketch in README.MD #10

Cannot compile the example shown in README.MD -> Usage -> Creating the main sketch. Only the first error message of the very long list (naturally perhaps owing to my newbie mistake) is shown below:

Board is Generic ESP8266. Tried other variations but still unsuccessful. What would be the recommended board for a Hello World type of exercise?

The text was updated successfully, but these errors were encountered:

Are you able to successfully compile a normal FastLED example sketch?

Also the provided output just shows a warning. It would be great if you could show the entire output.

Hello @stnkl,

Thank you very much for stepping up. Granted 99% are error messages. Here is the error message for a Generic ESP8266 Module board. (I dropped the idea of trying to make it work with the LOLIN(WEMOS) D1 R2 board):

FWIW, the simplest FastLED example compiles with the Generic ESP8266 board but I would like to use your library. I've just started using IDE 2 (at 2.0.3 now). I don't have to use ESP8266 for self-paced learning purposes. Let me know which board you would prefer that I do my first test. Thanks.

Regards.

The output for the compilation of the simplest FastLED example for the same Generic ESP8266 follows below:

The final message is Done Compiling. I've haven't rigged my setup to transfer the code to the board. The code is:


#include <FastLED.h>

#define NUM_LEDS 100
#define LED_TYPE WS2813
#define DATA_PIN 5

CRGB leds[NUM_LEDS];

void setup()
{
 FastLED.addLeds<LED_TYPE, DATA_PIN>(leds, NUM_LEDS); 
}

void loop()
{
	leds[0] = CRGB::White; FastLED.show(); delay(30);
	leds[0] = CRGB::Black; FastLED.show(); delay(30);
}

Is there a compiler option to suppress warning messages? Thanks.

Regards.

Looks like there is two things coming together:

Apparently Arduino is now using C++17 and therefore the register keyword does not exist anymore, leading to those warnings. ISO C++17 does not allow 'register' storage class specifier anymore FastLED/FastLED#1457 Unfortunately I couldn't really find a way to specify the C++ version specifically in my tests.
There seems to be a bug in the ESP8266 platform version 3.1.0 which has supposedly been fixed only a few hours ago in version 3.1.1 (Fix C builds esp8266/Arduino#8795). Looks like it surfaces with arduinoWebSockets, which FastLEDHub is using. Could you try updating to 3.1.1?

Unfortunately I can't reproduce the second error on my machine, even not with platform version 3.2.0 so it is a little hard for me to say what exactly is going wrong.

I don't think it really matters which board you use for testing as it should not fail like this for any of them.

For disabling the warning you can add the compiler flag -Wno-register, which will disable this particular warning. Since I don't use the Arduino IDE, I don't know for sure how to set compiler flags there, but it looks like you can change them in the platform.txt file and add the flag to compiler.c.flags.

Hello @stnkl,

Thanks for your understanding. I will do as you have suggested. I will slowly but surely get there to using FastLEDHub.

Apologies again for seeking help through the Issues section when it was a self-inflicted operator user error.

Regards.

No worries. Let me know if you have any other problems!
