Hi all,

I made som simple test program in eclipse cdt and compiled it. That works fine. code:

#include <iostream>


int main( ) {
	std::cout<<"";
	std::cout<<"print this.";
	return 0;
}

If i want to run the program, it doesn't print out anything. But, if i run it from the cmd or in netbeans, it all works fine. Also, when i want to debug the project, it doesn't work either, but it does in netbeans( error: "No source available for "main() at 0x4013d7" ")

Any ideas to fix this?

I guess you are working on Windows. There is a known problem with the console output. See

Did you build with debug info enabled?

Thanks for replly!

I added the following lines to my code:

setvbuf(stdout, NULL, _IONBF, 0);
setvbuf(stderr, NULL, _IONBF, 0);

But i got the following errors:

../main.cpp:11:10: error: 'stdout' was not declared in this scope
../main.cpp:11:24: error: '_IONBF' was not declared in this scope
../main.cpp:11:33: error: 'setvbuf' was not declared in this scope
../main.cpp:12:10: error: 'stderr' was not declared in this scope

For debugging, what is 'build debug info enabled'?

You need #include <stdio.h> for setvbuf

Did you build a Debug or Release version?

It still doesn't work, this is my code:

#include <iostream>
#include <stdio.h>

int main( ) {
	setvbuf(stdout, NULL, _IONBF, 0);
	setvbuf(stderr, NULL, _IONBF, 0);
	std::cout<<"";
	std::cout<<"print this.";
	return 0;
}

Currently, debug is the active configuration.
