two things..........

two things..........

[Graham Walsh]

Hi,

I have two issues;


1) link failure with "atexit" already defined, this is with gcc v3.2 for c++ 
in conjunction with the latest cygwin installation.


2) I think I need to update my gcc installation to overcome this first 
issue. I wonder if you can tell me where there are pre-built versions of the 
gcc c++ compiler so I can download and run on my friendly xp laptop. I don't 
want to go thru the pain of compiling the gcc source from scratch, hence the 
request for the pre-built compiler.


cheers much,


GrahamO

Hi,

does your compiler report some warning like "implicit declaration of atexit()"? Try to import the atexit symbol from the std:: namespace:

#include <cstdlib>
#include <iostream>

using std::atexit;

void foo( void )
{
	std::cout << "Bye bye" << std::endl;
}

int main( int argc, char** argv )
{
	atexit( foo );

	return 0;
} 

This should work in any gcc v3 compiler.

Miguel.

Hi Graham,

The pre-built version of GCC C++ compiler is downloadable through Cygwin's SETUP program.

It isn't selected by default, you'll have to make sure you click on "install" for the compiler.  (Or do what I do, and click "install" at the top level item and install pre-built EVERYTHING (sans source).)

HTH,
