Code Blocks compilation error - c

Whenever I am trying to build and run a program the second time this error is coming on the screen:
cannot open output file C:\Users\Username\Documents\filename.exe Permission denied


You either 1. don't have permissions to write to the directory(unlikely)
or 2. Your executable is still in the memory. Hit CTRL+ALT+DEL select Windows Task Manager and Find+End your executable "filename.exe".


It means The directory your code is in doesn't have write permission. But try moving your code in some write permitted directory. BTW in my windows this problem occurs sometimes. Then when I restart codeblocks it disappears - I am not telling this is a solution.

Access is denied while running a C output

I am getting an error while running the output(a.exe) of a C program. Command prompt showing "Access is denied". I have reinstalled gcc but same problem is arriving. Here is the screenshot of error

That output is seen, when you try to run a x64 binary on a x86 system.
But there are numerous other possibilities.
Another likely possibility is your Antivirus realtime scanning.
Be sure it does not block access for you.
Provide more details and I'll update this accordingly.

SAS program runs interactively but not as batch file - issues authorizing access to drives

I have a SAS code which works flawlessly when I first open the program and run the code interactively. However, if I try to run it as a batch file or execute it from the command prompt using the -sysin option, it doesn't run and I don't know why.
Part of the reason might be that when I run SAS, I receive this dialog box which I need to manually close:
Screencap 1
When I try to choose the option "Do not show this dialog box again" it doesn't work, and it shows the dialog every time I open SAS. This may be because my registry and profile files are corrupted:
Screencap2
Would this be the reason why? If I run the program interactively after closing the dialog box, the program run just fine. I tried to follow some steps to repair the registry and profile files, but it didn't work. Is that what I should focus on, or is there likely another reason it won't run in batch?
Thanks for your input!
edit: I was able to get the program to run from the batch file, but I get the following errors about permissions in the log file:
ERROR: Insufficient authorization to access //destinationonselecteddrive
NOTE: The SAS System stopped processing this step because of errors.
NOTE: PROCEDURE PRINTTO used (Total process time):
real time 0.01 seconds
cpu time 0.00 seconds
I do not have these issues with insufficient authorization when I run the program interactively, only in batch mode. Could it be a metadata issue?

You have to check with which profile your batch is running. When run interactively it may (and it will normally) use a different profile than the one you are using while running interactively. That means different user and password. You can check in the management console (or ask your administrator to check).

It sounds most likely like there is a problem with the user profile. At my old job I ran into problem with the profile when I ran concurrent SAS sessions. I had to set my user profile to read only using the RSASUSER option (SAS instruction here). If that is not the issue try creating a new profile catalog in a new location and then adding the -SASUSER option with the new location (SAS info on how to do that).

Unable to run C programs using any compiler

I had to write code in C and run it for an assignment. Since this is the first time that I'm using C, I downloaded MinGW as a compiler and Code Blocks as an IDE. I had no problem compiling the code given by my professor but it never runs (this is a simulation for an M/M/1 queue). When I say it never runs, I mean that a command prompt like window pops up and nothing happens after that. Every time I close that window and try to compile the SAME program again, I get an error that says that permission to access the file has been denied.
I then deleted Code Blocks and tried running the program through command prompt but I have the same problem. I've now tried doing it using LCC-Win but nothing has changed. Another weird thing that happens when I run any program is that three instances of the .exe file of that particular program are in my processes under task manager. I then need to restart my computer to try compiling that same program.
I even tried running a simple Hello World program and I have the same problem!
I am currently using a Windows 7 32-bit system.
Any help would be greatly appreciated!

Permission denied - cannot open outputfile

Now and then I get this compilation error when compiling a c-file in Eclipse.
c:/mingw/bin/../lib/gcc/mingw32/4.7.2/../../../../mingw32/bin/ld.exe: cannot open output file main.exe: Permission denied
It happends when I have made a change in the source-code - but not always.
I know how to solve this* but I would like to know WHY it occurs and how to avoid it?
*In eclipse I go to the debugger and terminate the main thread of the program

You said it yourself, it happens because the program being compiled is still running.
In Windows, you can't make changes to the exe file of a program when it's running.
It's fantastically annoying, and one of those things that (to me) make Windows slightly less comfortable than e.g. Linux for development.

ld.exe: cannot open output file ... : Permission denied

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?

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.

Your program is still running. You have to kill it by closing the command line window.
If you press control alt delete, task manager, process`s (kill the ones that match your filename).

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.

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

The Best solution is go to console in eclipse IDE and click the red button to terminate the program.
You will see the your program is running and output can be seen there. :) !!

I had the same behaviour, and fixed it by running Code::Blocks as administrator.

Open task manager -> Processes -> Click on .exe (Fibonacci.exe) -> End Process
if it doesn't work
Close eclipse IDE (or whatever IDE you use) and repeat step 1.

I had a similar problem. Using a freeware utility called Unlocker (version 1.9.2), I found that my antivirus software (Panda free) had left a hanging lock on the executable file even though it didn't detect any threat. Unlocker was able to unlock it.

Got the same issue. Read this. Disabled the antivirus software (mcaffee). Et voila
Confirmed by the antivirus log:
Blocked by Access Protection rule d:\mingw64\x86_64-w64-mingw32\bin\ld.exe d:\workspace\cpp\bar\foo.exe User-defined Rules:ctx3 Action blocked : Create

It may be your Antivirus Software.
In my case Malwarebytes was holding a handle on my program's executable:
Using Process Explorer to close the handle, or just disabling antivirus for a bit work just fine.

i experienced a similar issue. Bitdefender automatically quarantined each exe-file i created by MinGW g++. Instead of the full exe-file i found a file with a weird extension 'qzquar'
testAutoPtr1.exe.48352.gzquar
When i opened quarantined items in Bitdefender i found my exe-file quarantined there.

I got this error when using the Atom editor and mingw (through a package called gpp-compiler) for C++. Closing the open console window fixed my issue.
