All Eclipse C++ Programs Fail to Run, Hangs on "Launching Delegate" [message #1714656] Sun, 15 November 2015 03:27 Go to next message

Hi folks,
A few days ago, Eclipse for C/C++ (Helios) stopped running my programs. They can be compiled with MinGW without displaying any errors. However, when the programs are run, Eclipse always get stuck at "Launching Delegate" at 70%. No matter how long I wait, the program never starts. The same happens when I try to run the program from the command line; no matter how simple the program, the command line just does nothing, as if it is waiting for the program to start.

I believed that this was just an issue with my Eclipse workspace, so I created a new workspace and tested a Hello World application, but it failed too. I reverted to an older version of Eclipse (Indigo), and a 32-bit version, but these had the same error. I even installed a different IDE, Netbeans, but it too never runs any programs. So, clearly, it's not just Eclipse. I tried reinstalling MinGW, but this also didn't help.

I have tried everything I can possibly think of. I could only find one other person with the same problem online, and theirs was never answered. Can anyone help me out with this strange issue?

You said it stopped working a few days ago. What changed?
I had an issue with the Mars version right after I did a system update. Seems Eclipse was mixing things from different versions.
Not saying this is your problem but something to consider.

I had this same exact problem. Everything compiled properly but wouldn't launch, even from Command Line.

After searching endlessly I have found that, for me, the issue was my anti-virus program, Avast. It blocks all c/c++ programs I make. Try pausing your anti-virus and running it again.
Hope this works for you.

You are very welcome. I had stumbled on your post trying to find a solution myself. That problem was insanely frustrating so I made sure to let you know.
