In diesem Beitrag beschreibe ich den Prozess der Einrichtung der IDE und schreibe den ersten Hello World in x86_64-Assembler f\u00fcr das Ubuntu-Linux-Betriebssystem.
Beginnen wir mit der Installation der SASM-IDE, Nasm-Assembler:<\/p>\n

Hello World-Code aus dem Blog  James Fisher<\/a>, angepasst f\u00fcr Assemblierung und Debugging in SASM. In der SASM-Dokumentation hei\u00dft es, dass der Einstiegspunkt eine Funktion namens \u201emain\u201c sein muss, da sonst das Debuggen und Kompilieren des Codes fehlerhaft ist.
Was haben wir in diesem Code gemacht? Habe einen Systemaufruf get\u00e4tigt – Zugriff auf den Kernel des Linux-Betriebssystems mit korrekten Argumenten in Registern, einem Zeiger auf eine Zeichenfolge im Datenabschnitt.<\/p>\n
Unter der Lupe<\/h3>\n
Sehen wir uns den Code genauer an:<\/p>\n
