C++ compiler for windows 7 64 bit ?

Hi ,
can anyome recommend a good free compiler (command line would do but even better if it has a dev environment) for C++ on a 64 bit OS ? (win 7)

Cheers

gcc compiler through Cygwin would fit the bill. Is the code you wish to write windows specific? If it is, sticking with Visual Studio may be the best bet. If not, Cygwin is quite decent. It's great to have a Unix enviroment within Windows imo.

I haven't a clue about 64 bit, but I use the GCC Compiler through Codeblocks. I have 32-bit Windows 7.

another thing, if i have a void main function, I get am error saying main needs to return an integer ????

has c++ changed ??
when I was in college a return; statement at the end of a main where main is void was fine -not even a warning - now i get an error cos of this.

Can I write "void main()"?

The definition
void main() { /* ... */ }
is not and never has been C++, nor has it even been C. See the ISO C++ standard 3.6.1[2] or the ISO C standard 5.1.2.2.1. A conforming implementation accepts
int main() { /* ... */ }
and
int main(int argc, char* argv[]) { /* ... */ }
A conforming implementation may provide more versions of main(), but they must all have return type int. The int returned by main() is a way for a program to return a value to "the system" that invokes it. On systems that doesn't provide such a facility the return value is ignored, but that doesn't make "void main()" legal C++ or legal C. Even if your compiler accepts "void main()" avoid it, or risk being considered ignorant by C and C++ programmers.
In C++, main() need not contain an explicit return statement. In that case, the value returned is 0, meaning successful execution. For example:

#include<iostream>

int main()
{
std::cout << "This program returns the integer value 0\n";
}
Note also that neither ISO C++ nor C99 allows you to leave the type out of a declaration. That is, in contrast to C89 and ARM C++ ,"int" is not assumed where a type is missing in a declaration. Consequently:
#include<iostream>

main() { /* ... */ }
is an error because the return type of main() is missing.
