Compile problems #1

Open georgeHayRiv opened 1 year ago

georgeHayRiv commented 1 year ago

When trying to compile this code I am getting four variables with "multiple definition of ". The problem (in Red) sections from the Arduino error messages are listed below. Both the main sketch and homekit_config.c include the homekit_config.h file. It should not get loaded by both but appears to be doing that. Could the "#ifndef HOMEKIT_CONFIGH99D20943_B47B_45CD_AF23_FF497B9150D8" line not be working?

I have tried the Wemos D1 mini and NodeMCU boards. The Arduino IDE also required for the folder name to match the name of the .ino sketch name. I have tried moving lines 44-47 in homekit_config.h into different files without success. Any suggestions?

I was able to pull out just the HomeKit code and add it to a different Arduino sketch and get it to work. I never did figure out the compilation problem with the code as it is.
