Intenté ejecutar:
gcc -o main main.c squrt.S -lm -no-pie
Esto funcionó en una computadora diferente, pero esta vez no conocía una sola instrucción:

¿Hay algún paquete que tengo que instalar?
Respuesta1
El lenguaje "ensamblador" depende de la arquitectura, ya que su objetivo es escribir directamente instrucciones de la CPU, y cada tipo de CPU tiene otras diferentes. Todo su programa está escrito en código ensamblador amd64/Intel x86_64, pero Raspbian no se ejecuta en ellos: se ejecuta en dispositivos ARM, por lo que el estándar gccque viene también espera el ensamblaje ARM.
(Eche un vistazo lscpuy gcc -dumpmachinedescubra qué tipo de CPU tiene).
Si desea que el programa se ejecute en CPU ARM, debe reescribirlo todo. (Probablemente) no existe ningún paquete gcc que pueda compilar un ensamblado x86 para ejecutarlo en ARM, aunque haypodríaSeamos traductores para ayudarle a reescribir.
Si desea que el programa se ejecute en CPU AMD64/x86_64, pero solo lo compile en Raspbian, debe instalar un compilador cruzado. (Podría estar en gcc-x86-64-linux-gnu + binutils-x86-64-linux-gnu).
