Description

When attempting to compile serverino on a Raspberry Pi 4, the following error occurs:

Grazie Orfeo :)

Domanda: perché usi la versione a 32 bit?

Ciao Andrea, innanzi lasciami complimentarmi per l'ottimo lavoro che hai fatto: e' veloce, leggero, ben documentato ed (cosa piu' importante) elegantemente scritto.
La raspberry comunica con dei dispositivi a microprocessore e purtroppo ne abbiamo centinaia in giro e devo mantenere la compatibilita'. La prossima versione uscira' a 64bit con server Rest implementato tramite il mitico Serverino.
Grazie ancora e buona serata
