Failed to compile examples of FabGL

[FernandoRoxo]

Terrible title, I know. Sorry.

I have Arduino IDE 2.3.2 installed, installed FabGL 1.0. using the Library Manager and installed esp32 3.0.2 by espressif as instructed by many videos on internet (preferences->Additional boards manager...).

The Arduino IDE is the 'arduino-ide_2.3.2_Linux_64bit.AppImage' on Linux Ubuntu 20.04.

I selected the ESP32 Dev Module and started compiling the example sketches from FabGL.

The first I have tried was the VIC20 with the partition Scheme Huge App. The compilation finished with the error:

/tmp/.arduinoIDE-unsaved2024611-1038633-wjo2zo.5ue8c/VIC20/VIC20.ino:38:17: note: '#pragma message: This sketch requires Tools->Partition Scheme = Huge APP'

I tried to compile the Atari8800 and it finished with:

Compilation error: exit status 1

I have tried to compile the following:

ANSI Terminal, Audio, ClassicRacer, ColisionDetection, DirectVGA, Hardware Test and Loopback Terminal

All of them finished the compilation with errors, the first one being:

  Am I missing something?   Perhaps the version of the Arduino IDE?

  If this in not the forum for this, please let me now and, if possible, point  me to the correct one.

  Thanks in advance.

I have moved this to the discussions, seems to fir better there. I couldn't find a way to close or remove this issue.

😒

I get this when using v3 of the esp32 board library in the arduino SDK, if you pick the final version of v2 (2.0.17 for me) the examples no longer produce this error.

Good Luck!

Hi Xalior,

Thank you very much. I have installed the version 2.0.17 and the examples compiled without problem
