librairie LVGL

Bonjour à tous ,

j'aurai besoin d'un petit coup de main pour mettre en œuvre la librairie LVGL (Light and Versatile Graphics Library)
que j'essaie vainement de faire tourner à partir d'un exemple pris ici :

https://randomnerdtutorials.com/lvgl...ile-windows-pc

j'ai, semble-t-il, suivi toutes les recommandations mais à chaque compilation du programme de test , il affiche :

Code:
