kan ikke forstå

hvis det er en anden CPU arkitektur så vil selve instruktionerne
være anderledes

hvis det er en anden compiler vil library kald være anderledes

hvis det er et andet styre system vil image formatet (headere og angivelse
af sektioner) være anderledes

okay det var jo hurtigt!
hvad er det der står i library filen. trode bare at binary filen kaldte nogen standart komandor fx. at printe et eller andet ud på skærmen

calling convention kan være forskellig mellem forskellige compilere

der kan også være kode som bliver oversat til funktions kald der ikke
er standardiseret

og når man begynder at kigge på indholdet af librariet så vil selv standard kald jo kalde
nogle helt forskellige funktioner på forskellige styre systemer

okay tak for svaret.
bare læg et svar.

Har du prøvet at eksperimentere lidt med at få compileren til at vise
den genererede assembler kode ?

#include<iostream>

using namespace std;

int main()
{
    cout << "hello world" << endl;
