Can't compile using PlatgormIO #63

Open samarkh opened 10 months ago

samarkh commented 10 months ago

Hi I get a whole load of "error: 'debuggingMode' was not declared in this scope" errors when I try to build this project using PlatformIO. I have no problems using Arduino 2.x. Has anyone got any suggestions?

Yours Simon M.

Hi. I ran into the same problem. Found a workaround by adding extern boolean debuggingMode; next to: extern QueueHandle_t callbackQueue;

in the end of file: esp32_can_builtin.h I did not investigate much further since I'm only gonna use the built in can-controller.

Seemed to pass the build process but got stuck at linking..

Finally got it uploaded using even uglier workaround by initiating the boolean in begining of each function were used :/
