Eclipse CDT using MinGW does not output in console

Question

I have a Windows 7 64-bit PC and I am trying to install a free C++ IDE, so I chose to install Eclipse Helios with CDT.

For g++, make and gdb I installed msys and mingw according to this tutorial: http://wiki.wxwidgets.org/HowTo:_Install_MSYS_and_MinGW_for_use_with_Eclipse_CDT

The versions are:

• make: GNU make 3.81
• g++: 4.5.0
• gdb: 7.1

So it should be compatible with my 64-bit CPU.

However when I try to run a very simple program with eclipse, I see nothing on the console. The source code is:

#include <iostream>   using namespace std;   int main()  {     int i;      cout << "Enter an integer: " << endl;     cin >> i;     cout << endl << "i is " << i << endl;      return 0;  } 

The build is fine and when I launch the .exe with command (windows console) the behavior is as expected. But with the Eclipse console I see nothing with run and with debug the output is just: "Enter an integer: ", then when I type in a number and hit enter it does nothing.

Does anyone know how to fix this please?

Thanks,

Guillaume

PS: I use the toolchain "Linux GCC", with "MinGW GCC" I have nothing at all in the console.

Answer 1

This worked for me on 64-bit install of Eclipse on Windows 7 using MinGW:

Right-click on your project. Select "Properties".

Select the "Run/Debug Settings" Property on the left of the new window.

In the right window, click on your executable to highlight (ie - Test.exe) and click "Edit".

In the Environment tab, hit "New"

Name: PATH
Value: Path to your MinGW bin directory. (For me this was: C:\devcore\MinGW\bin)

Click "OK" on all windows to close down.

Try running again, it should print output to the screen.

You need to set up linker I am using MinGW.

Follow below steps.

Goto Project > Properties > C/C++ Build > Settings > Tool Settings (Tab) > MinGW C++ Linker (Option) > Add Command (g++ -static-libgcc -static-libstdc++)   (default command is only g++)
