[BUG] (Neopixels install returning an undefined reference error)

[TeknikSaiko]

Bug Description

When adding the physical hardware of neopixels and ensuring the hardware works, I tried to fill out the neopixel code in configuration.h and then I built the firmware in platform.io (MEGA_P_DGUS_TMC). The code got built up until the very last part where is resulted in an error of

Archiving .pio\build\MEGA_P_DGUS_TMC\libFrameworkArduino.a Linking .pio\build\MEGA_P_DGUS_TMC\firmware.elf

Open the folder in VCS and navigate to configuration.h 2. Modify code from lines 3528 to 3538 // Support for Adafruit NeoPixel LED driver #define NEOPIXEL_LED #if ENABLED(NEOPIXEL_LED) #define NEOPIXEL_TYPE NEO_GRBW // NEO_GRBW / NEO_GRB - four/three channel driver type (defined in Adafruit_NeoPixel.h) #define NEOPIXEL_PIN 11 // LED driving pin //#define NEOPIXEL2_TYPE NEOPIXEL_TYPE //#define NEOPIXEL2_PIN 5 #define NEOPIXEL_PIXELS 20 // Number of LEDs in the strip. (Longest strip when NEOPIXEL2_SEPARATE is disabled.) #define NEOPIXEL_IS_SEQUENTIAL // Sequential display for temperature change - LED by LED. Disable to change all LEDs at once. #define NEOPIXEL_BRIGHTNESS 127 // Initial brightness (0-255) #define NEOPIXEL_STARTUP_TEST // Cycle through colors at startup 3. Go into platformIO --> MEGA_P_DSUS_TMC --> Build 4. Receive error above **Expected behavior:** [What you expect to happen] Code finishes compiling successfully into a hex file **Actual behavior:** [What actually happens] Failure and Error code C:\Users\"MY NAME"\AppData\Local\Temp\ccpFS0bN.ltrans2.ltrans.o: In function `GcodeSuite::process_parsed_command(bool)': :(.text+0x5884): undefined reference to `GcodeSuite::M150()' collect2.exe: error: ld returned 1 exit status *** [.pio\build\MEGA_P_DGUS_TMC\firmware.elf] Error 1****  #### Additional Information * Provide pictures or links to videos that clearly demonstrate the issue. * See [How Can I Contribute](#how-can-i-contribute) for additional guidelines.

Comment out -<src/gcode/feature/leds/M150.cpp> in ~ line 238 of platformio.ini. I think it should compile then.

Thanks! For some reason, I had to edit this out, compile it, and then add in the neopixel code but it worked. I appreciate it!
