Hi Gents,
I've installed the latest version of cygwin (as of today 2.03.04). My PC is
running Windows 2000 with service pack 4. Installation is done on my loca
drive d:. I tried a small "C++" and failed, the reason is totally unclear to
me.
The program is:
#include <iostream>
using namespace std;
int main()
{
int selection;
bool loop = true;
while (loop)
{
#if 0
cout << endl;
cout << "*********************\n";
cout << "* Learning bed C++ *\n";
cout << "*********************\n";
cout << ">>> CHAPTER 4 <<<\n";
cout << "=================\n\n";
cout << " 1: Review_5\n";
cout << "-1: Exit\n";
cout << "$ ";
cin >> selection;
cout << endl;
switch (selection)
{
case -1:
loop = false;
break;
case 0:
break;
case 1:
break;
case 2:
break;
case 3:
break;
case 4:
break;
case 5:
break;
case 6:
break;
case 7:
break;
case 8:
break;
case 9:
break;
case 10:
break;
case 11:
break;
}// switch (selection)
#endif
}// while (loop)
return 0;
}//main
The error message is:
$ gcc -o gtest gtest.cc

Desperatelly I installed the complete (!) cygwin - the result is still the
same.
When I set the #if 0 to #if 1the error message looks like:

What's wrong (template, path wrong, library missing)?
Can you help me, please?
Many thanks in advance.
