I got this error a while ago when compiling a project, and I've gotten it every few days since then, even in different projects, and the only solution that worked is restarting. Some people said to open task manager and close the file, but I couldn't find the file. Some people said to delete main.o in the obj/Debug or obj/Release folder, but they just reappeared when I compile. What else should I try? It's really inconveniencing having to restart every time it pops up.
check where you put the project maybe is in a file you have no access to it
run Code::Blocks as admin
make sure the program is not still running go to task manager and kill it
Don't just look under which programs are running
Check the processes list (Background Processes)and see if you can find a process running by the same name as your file.
Right click the process name
Choose end task. See if that works. It seems to have worked for
me.
I have qt project but if I edit my code, Qt creator throws out this error
:-1: error: LNK1168: cannot open debug\GettingStarted.exe for writing
I'm not able even to delete the debug folder (i.e. as an administrator). I have to log off and then come back. What is the problem and how can I solve it?
Go to the task manager Ctrl+Alt+Del.
look for the name of your running application in your case GettingStarted.exe.
right click --> end process or just press Suppr . This will kill the running process.
Go back to your code and run the application again
In my simple case (Qt only, no external libs, same error LNK1168) the Task manager showed nothing useful to kill.
Only total reboot has helped and error is gone.
All the methods mentioned here has not helped except reboot. There is no any ProjectName.exe in Task Manager.
You can go to C:\Users\user-name\source\repos\ProjectName\Debug\ folder and rename ProjectName.exe. You can't delete this file at that time, but It can be renamed. It can only be deleted after reboot.
I know this is an old thread but I was stumbling in the same problem also. Finding it in task manager is tricky, and I started to grow tired of having to restart my PC every time this happened.
A solution would be to download Process Explorer and there you can search for running tasks. In my case I was having the following error:
1>LINK : fatal error LNK1168: cannot open C:Out\Build\VS12_app\Debug\platform_test.exe for writing [C:Build\VS12_app\platform_test.vcxproj]
I searched for C:Out\Build\VS12_app\Debug\platform_test.exe in Process Explorer, killed it and I was able to compile.
Using debug I can run my project only one time. After that every time I get error:
cannot open output file debug\trud1.exe: Permission denied error:
ld returned 1 exit status
I close running Qt projects but seems like I can not close this one even via task manager (theres no tasks trud1.exe).
Explorer does not let me delete trud1.exe because it is used by my "System" (i can not kill this process).
Restarting Qt does not help me, only restarting computer does.
Please help me solve my problem.
This happens because you have to close the program you've launched before.
Look it isn't running on background.
I recently reinstalled Cygwin on my computer in order to get access to several command line elements that I was missing. I have never had previous difficulty with Cygwin, but after this reinstallation, an error message continues to appear after (almost) each command entered. For instance:
-bash-4.1$ wc m1.txt
3 [main] bash 2216 child_info_fork::abort: data segment start: parent(0x26D000) != child(0x38D000)
-bash: fork: retry: Resource temporarily unavailable
2013930 4027950 74968256 m1.txt
Generally, the command still runs (as seen above), but not always. Occasionally, the 'error' message occurs several times in a row (the initial number "3" will then change to a "4" or "2", notably if I start a second Cygwin window.
Also, as soon as I start up Cygwin, I get the following message before the prompt:
3 [main] bash 6140 child_info_fork::abort: data segment start: parent(0x26D000) != child(0x36D000)
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: Resource temporarily unavailable
-bash-4.1$
At the moment, I am debating whether to uninstall/reinstall Cygwin again or just live with the error messages, but I was curious if there might be an issue that I am unaware of.
(assuming Cygwin is installed at C:\Cygwin):
Open Task Manager and close any processes that look to be Cygwin related.
Open C:\Cygwin\bin in Windows Explorer
Verify that dash.exe, ash.exe, rebase.exe, and rebaseall exist in this folder
If any of them are missing, re-run Cygwin setup and select the dash, ash, and rebase packages
right-click your C:\Cygwin folder, uncheck Read-only (if its checked), and press OK.
When an error about not being able to switch some files comes up, select "Ignore All". Wait for this process to complete.
Browse to C:\Cygwin\bin in Windows Explorer
Right click dash.exe and click "Run as Administrator". A command Prompt should appear with nothing but a $
Type /usr/bin/rebaseall -v, hit enter, and wait for the process to complete.
If you get errors about Cygwin processes running, try Step 1 again. If that still doesn't work, Restart your computer into safe mode and try these steps again.
A commenter noted that, depending on your settings, you may have to type cd /usr/bin && ./rebaseall -v instead.
Try opening Cygwin again.
This process worked for me. I hope it works for you guys too.

I would like to add the following to the above answers, as it is what I had to do after reinstalling Cygwin:
Navigate to the "/usr/bin" directory (usually, C:\cygwin\bin) and right click, Run as Administrator the file: dash.exe
Then, at the $ prompt type the following, hitting enter after each line:
cd /usr/bin/
/usr/bin/peflags * -d 1
/usr/bin/rebaseall -v
What it does is, it marks the dll's as "rebase-able," and then rebases them. You have to have peflags.exe in addition to the above files (in previous answers). You may have to restart windows after doing this and you will definitely need to make sure that there are no processes nor services belonging to cygwin running. (Use task manager, kill any related processes, and then under the services tab look for any service starting with CYG and stop it.)
After doing this, I was able to get cygwin to run without any errors about dll's being loaded to the wrong addresses aka fork errors, etc.
I hope that this helps others, as it was a pain to find.
SOURCE: http://www.cygwin.com/faq.html#faq.using.fixing-fork-failures
and the rebase README file.
To add on to other answers here, we ran into the same issue but could not run the rebase command from the ash or dash shell. However, when launching the command from the Windows cmd shell, the following worked.
cmd /c "C:\cygwin64\bin\ash.exe /usr/rebaseall -v"
-v is to get verbose output
I found another information here :
http://cygwin.com/ml/cygwin/2014-02/msg00531.html
You have to delete the database at
/etc/rebase.db* and do in a "ash" windows :
peflags * -d 1
rebaseall
It works for me on 2 servers.
I solved this problem by restarting my computer. Probably installed a driver update and kept using sleep instead of shutting down.
Experienced the same issue when loading Cygwin with cygiconv-2.dll forking and not loading successfully in the Cygwin terminal, but after turning off my AntiVirus (it was specifically Ad-aware), the issue resolved, and Cygwin worked properly.
In case you are using babun's Cygwin, after rebaseall, try launching Cygwin by executing .babun\cygwin\cygwin.bat in a Windows command prompt or Windows explorer.
This works for me (while launching babun's default console - mintty results in fork error).
I had the error on win10 and i was trying to rebase to c: before install.
then i saw that the installer was installing it instead to c:/Users/myuser
so i was coping all files from c:/Users/myuser to c:.badun
and then restart plus open badun.bat
not shure if this was wise its now duplicated XD... but then it worked again.
Rebaseing didn't help in my case. In addition to what other people suggested, I noticed that reducing the length of PATH environment variable fixed the issue for me (and for other people as well as can be seen from this answer).
This issue is intermittent in nature & I found this issue when there is network is too slow to connect to remote machine on AWS.... I have Shell script that runs through Gitbash shell & it connects to AWS EC2 instance with ssh..... Most of the time, it ran correctly but 2 out 100 times it get into this issue bash: fork: retry: Resource temporarily unavailable .... Killing the MSYS2 terminal from task manager helps to overcome with this issue....
Negative side is you need to run the scripts from the beginning...
I had the same issue on Windows 10 and the mobaxterm app (which uses cygwin) and I tried all of answers listed here however for me, the solution was to simply delete the "CryptoPro CSP" application.
I started facing this problem after upgrading to windows 10. As of now I do not see that any of the above method working.
What I am noticing is that if you start cygwin with admin right (right click and say "run as admin") then it works fine.
Or you open cmd as administrator and then launch cygwin from there, then also it runs fine.
Just reinstall cygwin and select TCL and activate EXPECT
I already asked this question in the nvidia forum but never got an answer link.
Every time I try to step into a kernel I get a similar error message to this:
__device_stub__Z10bitreversePj (__par0=0x110000) at
/tmp/tmpxft_00005d4b_00000000-1_bitreverse.cudafe1.stub.c:10
10 /tmp/tmpxft_00005d4b_00000000-1_bitreverse.cudafe1.stub.c: No such file or directory.
in /tmp/tmpxft_00005d4b_00000000-1_bitreverse.cudafe1.stub.c
I tried to follow the instructions of the cuda-gdb walkthrough by the error stays.
Has somebody a tip what could cause this behaviour?
The "device stub" for bitreverse(unsigned int*) (whatever that is) was compiled with debug info, and it was located in /tmp/tmpxft_00005d4b_00000000-1_bitreverse.cudafe1.stub.c (which was likely machine-generated).
The "No such file" error is telling you that that file is not (or no longer) present on your system, but this is not an error; GDB just can't show you the source.
This should not prevent you from stepping further, or from setting breakpoints in other functions and continuing.
I was able to solve this problem by using -keep flag on the nvcc compiler. This specifies that the compiler should keep all intermediate files created during the compilation, including the stub.c files created by cudafe that are needed for the debugger to step through kernel functions. Otherwise the intermediate files seem to get deleted by default at the end of the compilation and the debugger will not be able to find them. You can specify a directory for the intermediate files as well, and will need to point your debugger (cuda-gdb, nsight, etc) to this location.
I think I had such problem once, but can't really remember what was it caused with. Do you use textures in your kernel? In that case you couldn't debug it.
