Impossible to compile

Development Tools IDE 1.x
1

Since sometime, I cannot compile any sketch with any board. The IDE runs correctly, but never compile anymore: ArduinoUno, or Mega2560, or STM32F10, with all my sketches (large sketches) or the very simple and classic "Blink.ino". What can be wrong in my configuration ? Thanks for your help.

The error message is :

The problem is you have an extra folder level in your Arduino_STM32 hardware package installation. Your current incorrect folder structure:

C:\Users\papa\Documents\Arduino\hardware
|_resource STM32 bluepill
|_Arduino_STM32
|_STM32F1

The correct folder structure:

C:\Users\papa\Documents\Arduino\hardware
|_Arduino_STM32
|_STM32F1

Fix the folder structure and the error will be gone.
