compile problem

[Bruce]

I don't know why it didn't compile with gcc
in cygwin. If I change cout to std::cout,
I got more errors .... could this be namespace
issue, or maybe setting in cygwin ? or maybe
some careless mistake ?

Pls help, thanks !


#include <iostream>
#include <iomanip>

int main()
{

cout << "test" ;

return 0;
}

#include <iostream>
#include <iomanip>

This is not used in your program.

int main()
{

cout << "test" ;

This needs to be std::cout. Also, you should terminate all text streams
with a newline for reliable output.

return 0;
}

Aside from that, there's nothing obviously wrong. Most likely your
compiler is either not installed correctly, or you invoked it
incorrectly. For more help on that you should consult a group that
discusses Cygwin or gcc. I'll offer a quick suggestion, though. Invoke
your compiler with the following command line:

g++ -W -Wall -ansi -pedantic -o output_file input_file.cpp

I don't know why it didn't compile with gcc
in cygwin. If I change cout to std::cout,

It should be std::cout.

Apart from that it's correct, it would obviously help us to help you if you
posted the error messages.

I don't know why it didn't compile with gcc in cygwin.

did you use the c++ compiler from gcc (gnu compiler collection) or the the
command gcc (gnu c compiler)? If you used the c compiler you should know
that it doesn't understand c++. You should use the command g++, which is
also part of gcc (compiler collection). The naming of gcc and gcc is very
confusing sometimes.

[snip correct program]

Don`t see anything wrong with this except the missing newline and the
unecessary header file.

#include <iostream>

Not needed:

#include <iomanip>



int main()
{

std::

cout << "test" ;

return 0;
}

The command line as i use it:

g++ -std=c++98 -pedantic-errors -O3 -Wall whatever.cpp -o whatever

#include <iostream>

int main()
{

cout << "test" ; std::cout << "test";

return 0;
}
