No output when running C++ applications via Eclipse CDT IDE [message #729002]

Eclipse can build my applications for me so far, and I can execute them directly (via Windows 7 Explorer), but I get no results when I use the run command via the CDT perspective. The console tab only tells me that the application terminated, even with a console app with input (cin >> and so forth). Win32 apps don't execute either. Once again I can execute them directly via the debug folder, so this must be an IDE issue. Is this normal? Or are there settings I could change to make it work?

Thanks for any advice! And please post if you are having the same issue!

Found the solution. It was because the workspace was under "Program Files", which has a space in it, and I believe MinGW rejects spaces for some reason.

I have the same 'no output' problem in Windows. Just trying to run this program -
#include <stdio.h>
int main() {
printf("Hello\n");
return 0;
}

I think it's finally Building correctly, but I'm not getting any output printed.
I've created this C project in both C:\Program Files and C:\EclipseC, in order to avoid the space. Also, the "Makefile" issue, it looks like I need to write my own Makefile, otherwise I get problems with creating a target and finding the executable file.
Thanks for any help.

Try adding a variable named PATH to the Environment section of your Run
Configuration and set it to C:\MinGW\bin or wherever the bin folder in your
MinGW setup is located.

Thanks - I think that worked, adding the PATH variable to Run Configuration.
I have versions of hello world that use a Makefile. I'm not sure I need to specify my own Makefile, it's possible Eclipse will do this for me, if I set up the project correctly?

And I also fixed the output problem by moving MinGW out of the Program Files directory. Make sure its directory contains no spaces!
