ld exe cannot open output file Permission denied

Question

I recently installed CodeBlocks with mingw32 on Windows 7 Ultimate 32bit in order to dust off my c skills  but this problem has me somewhat stumped   I decided to fire off a short Fibonacci generator to make sure my setup was working  but I ran into a hurdle    The program compiles  links and whatnot like a charm and I get a corresponding executable which runs as expected   The problems occur if I try to compile again  then I get the following   c  codeblocks mingw bin    lib gcc mingw32 4 4 1             mingw32 bin ld exe  cannot open output file bin Debug Fibonacci exe  Permission denied   I can t even edit the permissions of the generated executable   I ve checked the usual suspects    Executable is verily not running  Path to executable is read writable to mingw32  otherwise it wouldn t be able to build in the first place  I m not running cygwin in any shape or form    And now for the funny bit  Usually after a few minutes  any executables generated by mingw32 which are displaying this Access Denied behaviour will automatically vanish without any intervention from me   I ve googled this somewhat  but most of the other results were either vague or inapplicable   I wonder whether there is some Windows 7 security setting playing havoc with my  exe s  but I m not that knowledgeable about Win 7 as to know where to begin searching   Any one have any ideas

Problem Cause   The process of the current program is still running without interuption   This is the reason why you haven t got this issue after a restart   The fix is simple   Go to cmd and type the command taskkill -im process-name exe -f  Eg    taskkill -im demo exe -f   here                       demo - is my program name

I had exactly the same problem right after switching off some  in my opinion unneccessary  Windows services  It turned out that when I switched ON again the  Application Experience  everything resumed working fine   May be you simply have to turn on this service  To switch ON Application Experience    Click the Windows start buttonn  In the box labeled  Search programs and files  type services msc and click the search button  A new window with title  Services  opens  Right click on  Application Experience  line and select  Properties  from popup menu  Change Startup type to  Automatic  delayed start    Restart computer    Application Experiences should prevent the problem in the future

If you think the executable is locked by a process  try Process Explorer from SysInternals  In the File handle  enter Fibonacci exe and you should see who holds the file   If it is not enough  you can use Process Monitor  from SysInternals  again  to follow the activity of all processes on your system on Fibonacci exe  With a little bit of analysis  call stacks   you ll may find out why the access to the file is denied and what make it disappear
