Yocto ne peut pas compiler de manière croisée l'application GoLang Wails

Contenu de la question

J'utilise yocto kirkstone pour créer un système de construction de carte Linux intégré personnalisé pour armv7. J'ai la version 1.20 de Go-Runtime dans mon métalayer yocto.

J'essaie de créer un exemple simple d'application Golang "wails" (https://github.com/wailsapp/wails) que je peux créer sur un Mac pour ma cible. Cela nécessite que wails 'cli' soit installé pour construire l'application. Je ne sais pas comment compiler cette application avec yocto. Comment puis-je faire ceci? Merci.

Cette commande échoue dans do_compile() :

wails build .

L'erreur que j'ai reçue ressemble à ceci :

Bonne réponse
