Hi, my C++ program is just these few lines:
/****************
* Helloworld.cpp
*****************/
#include <iostream>
#include <string>
using namespace std;
int main()
{
string s = "Hell! O' world, why won't my c++ code run?\n\n";
cout << s;
return 0;
}
The program runs okay on the router board if just printf is used. But once I
switch to use string and cout I get the "Illegal instruction" error.
BTW what is inline asm? Thank you.
Chiang
