[Bearbeiten] Ruby erweitern mit c und c++
Da genug Beispiele für Ruby auf Linux-Systemen zu finden sind, bezieht sich der nachfolgende Artikel auf Erweiterung von Ruby mit Hilfe C und C++ auf Windows Systemen.
Da die Entwicklung der Sprachen stetig erfolgen, ist die Version 6 Visual C++ nicht mehr zum Downloaden zu finden. Aber in Büchereien gibt es Bücher mit Demo Version 6 von C++ zum Erlernen der Sprache.
