I'm running the latest version of Eclipse with CDT on Windows 64 bits with Cygwin for compiling the code.

My problem is that when i run any c++ software in eclipse, there is no output in the console.

I have tried this:

Eclipse CDT debugger does not show console

and this:

Eclipse CDT Debug console not displaying program output

But it does not works.

    What do you believe the program should write to the console and why? – johnsyweb Nov 11 '11 at 20:23
  • My program is just a simple Hello World file. Here it is: #include using namespace std; int main() { cout << "Hello there!" << endl; return 0; } – Phil Nov 11 '11 at 20:28

As guys at "No Console Output (MinGW, CDT)" point out, this is probably (or at least sometimes) because Eclipse does not add PATH to MINGW\bin when launching the executable, so:

In the "Environment" tag, press "New", set it as:

  • "Name:PATH"
  • "Value:C:\MinGW\bin"

;)

  • @Phil Thanks, that's touching (I just had a similair problem and googled through this page to that one...) ;) – mlvljr Mar 27 '12 at 21:23

    For those who don't know, On Eclipse 3.7.2 and CDT 8.0.2 the preferences for environment variables can be found in Eclipse at: `Window > Preferences > C/C++ > Build > Environment` – Sheharyar May 17 '13 at 13:39

Another solution that works (other than mlvljr's) is by adding the -static flag in:

Project > Properties > C/C++ Build > Settings > Tool Settings > MinGW C++ Linker > Miscellaneous > Linker Flags

Project > Properties > C/C++ Build > Settings > Tool Settings > MinGW C++ Linker > Miscellaneous > Linker Flags (add -static)

If All above is not working then You can try this

You have to add Environment variable of this project to have the path of MinGW compiler

Goto Project->Properties->Run/Debug Settings, choose the .exe file and press Edit In the Environment tag, press New, and set it as: Name: PATH Value: C:\MinGW\bin

If you are using cygwin then Value: c:\cygwin\bin

Make sure the console is allocated:

project properties --> Run/Debug Settings --> yours.exe --> edit --> Common --> Check 'Allocate Console'

  • Is there any output to the console during the build process? – Tom Nov 11 '11 at 20:46
  • Yes. I have found the problem. I have updated eclipse and now it works :-) Thanks for your suggestions. – Phil Nov 11 '11 at 21:58

Thanks for the answers. I have found the problem. It was a bug from Eclipse.

I went in the Help > Check For Updates.

I installed an update and now it works!

I faced this issue not long ago. Follow this link which provides quite a detailed tutorial on how to setup everything. However, the console on Eclipse Mars CDT still did not show anything. After running the generated executable file from the command line i faced the following error:

Apparently some path was missing

So considering the missing path I searched for it on cygwin main folder and added to the Project Properties -> C/C++ General -> Paths and Symbols -> Includes GNU C++ the path to the missing dll folder: ${CYGWIN_HOME}/usr/i686-pc-cygwin/sys-root/usr/bin. Run again the project, and the problem was solved:

I hope this will help somebody!

As Singhak answered, this issue can be "fixed" on a project-by-project basis by adding a PATH environment variable to the project's Launch configuration: Project > Properties > Run/Debug Settings > (select the project executable) > Edit.. > Environment > New... (Name: PATH, Value: path/to/compiler/bin). But you'll have to do that for every project - I don't think there's a way to set it up to work for every project, at least I have not been able to.

However, if you're running Windows and have MS Visual Studio installed, you can set the project up using Microsoft Visual C++ Toolchains instead of GCC and that should work as expected every time.

I think this night be connected to the order in which I installed MinGW and eclipse CDT (Helios). The solution (for me) was to go Project -> Properties -> C/C++ Build -> Settings -> Tool Settings -> MinGW C++ Linker -> Miscellaneous -> and set Linker flags to -static-libgcc -static-libstdc++. But I seem to need to do this for every project so I'm still searching for a permanent fix.
