"Cannot Open a.exe" Error in C++

I'm trying to compile my C++ program, but when I press the "Build" button, it displays the following error message:

c:/gnat/2010/bin/../libexec/gcc/i686-pc-mingw32/4.3.6/ld.exe: cannot open output file a.exe: Invalid argument collect2: ld returned 1 exit status

This is not the first time it has done this. It seems to do this most when I have been editing the same project a lot and building it often, almost as if something has been flooded, or overloaded, or something.

I had fixed it before, I believe, by restarting my PC, but I can't afford to keep restarting my PC every time this occurs.

I thought this was just a one-time problem, but it has continued to happen and so I thought I'd look for more help on this.

I found another SO question that I thought had the same error message/problem as I had. However, when I tried the solutions listed on afore-linked question, nothing helped.

Has anyone else had this issue? Or does anyone know how I can fix this issue (besides restarting my computer every time)?

I am developing in jGrasp also, if that helps any.

EDIT: I just wanted to ad开发者_开发知识库d that I thought it might be that my previous executable was still running in the background, but even if I close my IDE, it still won't let me delete the executable, because it says it is still running.

I checked my process explorer to see if the a.exe was still running, but there's absolutely nothing in my processes that has to do with jGrasp or a.exe

I guess your executable is still running. It's the only reason I think about... I guess the best is to check on your task manager (process Explorer is your friend ;)).

In Visual Studio Code, go to Settings -> Search for "clear previous" in the search bar and check on the box named "clear previous output". :)

It is happening because your previous output is already running in the background. And VS Code offers a feature to close that on every run.

EDIT: it's nothing to do with collect2.exe.

Do you get any other error text, like for example 'permission denied errors' etc.

It is beacause the .exe is still running. If you're on Windows use the command line del -f a.exe and if you're on linux use rm -rf ./a.out

I have the same problem, was worried for hours. I disabled my avg antivirus and it worked.
