Cannot open output file permission denied

Question

So I keep getting this error when trying to compile C   code using CodeBlocks      cannot open output file  filename exe  permission denied   It only started today  and it s sporadic and inconsistent   It usually goes away if I shut CodeBlocks down and restart the project  but not always   Sometimes it even goes away when I just press F9  build  amp  run  several times   I always check Task Manager  but there are never any  EXEs running with my file s name  or anything related to it     I ve also noticed that if this problem occurs and I then try to delete the  EXE manually or otherwise interact with it  Windows tells me I need administrator permission to do so  this is a private PC  and as far as I know I am an administrator on it    The first time it occurred  the only thing I had added to the code beyond what was in the previous version was a debugging report sent to cout - hardly anything arcane   It sometimes occurs even when no code was changed from a previous version   What could this be   It s not game-breaking  yet  but it s irritating and I d rather it didn t get worse   EDIT  This is old by now  but just in case anyone else is having similar problems  the workaround I currently use is just to consistently delete  filename exe  before trying to run the code again   This avoids the problem  though it is annoying

I just had the same issue  And i experienced that it always happens when i run the programm and change some code without finishing the programm still running  After that the  cannot open      message appears   However i got rid of it by clicking the  Terminate  button at the very top-right side of the console window  red button  and after that  remove all terminated launches   two x es right next to the terminate button   This seems to close the running programm and everything works fine after    hope this may help anyone

I have encountered the same problem you have  I found that it may have some relationship with the way you terminate your run result  When you run your code  whether it has a printout  the debugger will call the console which print a  Press any key to continue      If you terminate the console by pressing key  it s ok  if you do it by click the close button  the problem comes as you described  When you terminate it in the latter way  you have to wait several minutes before you can rebuild your code

This error usually occurs when the IDE has a problem due to a crash or other failure and it still has a hold on the EXE  preventing the user  yourself  from overwriting   deleting the EXE during a rebuild

I was having the same problem too and it was driving me crazy   Windows7 64 bit  MinGW  Eclipse  CDT  Permission denied errors  executable disappearing  ld exe errors  It would work once  but never again  Statements like   cannot open output file     exe  Permission denied   Check your ANTIVIRUS Software  Once I turned off my Antivirus software in workspace then cleaned the workspace and started the project over again I never had the problem again

check that  filename exe  is not running  I guess you are using Microsoft Windows  in that case you can use either Task Manager or Process Explorer   http   technet microsoft com en-us sysinternals bb896653 to kill  filename exe  before trying to generate it

The problem is that you don t have the administrator rights to access it as running or compilation of something is being done in the basic C drive  To eliminate this problem  run the devcpp exe as an administrator  You could also change the permission from properties and allowing access read write modify etc for the system and by the system

A major cause of this  which I had recently   is if you have this on for example a flash drive   You can develop and do everything  but on most systems it stops you from running the  exe file from there  whether it be the debug or release version
