I'm using Eclipse Helios in Windows7 for C/C++ programming. I wrote a basic C++ code and tried to compile. The output is:
**** Incremental Build of configuration Release for project Programming Project **** Info: Internal Builder is used for build g++
-o "Programming Project.exe" "src\ch_3_excercises.o" c:/mingw/bin/../lib/gcc/mingw32/4.6.2/../../../../mingw32/bin/ld.exe:
cannot open output file Programming Project.exe: Permission denied
collect2: ld returned 1 exit status
How can I fix this error?
All you have to do is go to project on the menu bar and then click clean project. Clean all of your projects and then it should work.
The same problem with me while editing my code.the easy way i used is ::::::::
press the red button(Terminate) before editing your code then run your code
it is tested and works
I know this is an old question, but it probably does that because you are interrupting the flow of your program, for instance using scanf(), and not actually giving the input it requires, so when you use the command Build the project, then eclipse is waiting a stream from your keyboard (for instance, maybe it's a different type of program, but follow me here).
Once you know than that is the problem, then you might wanna keep an eye in what is that you are not giving to the project and that it is expecting you to; and the way to stop this annoying error the next time you get it, is that in your console view you press the red button.
That will happen if the program is still running in another window. The .exe file stays open until the program finishes execution, and you can't delete a file while any processes have it open.
I don't use Eclipse for C/C++ development, and the problem almost can't happen with Code::Blocks, but this happens very often with Visual C++. Just close the other window and rebuild.
Check your quarantine folder of your antivirus. If you see the executable file, then add it to the Trust list or White list. Your problem should be solved.
It means the same .exe file is running in your system.
A program cannot be build when its already running.
So the simple and most obvious thing to do is:-
Open task manager
Find <yourfilename.exe> under processes
Right click and end task
This stops it from running in background.
So you can build your program anew and run.

I am new to Visual Studio and I really don't have any idea of how it works.
I tried to make a simple "Hello World!" to print in C++, and started debugging.
But then I got the following message:
"Unable to start program
'c:\Users\name\source\repos\Project\Debug\Test.exe'
The file was not found."
I saw someone on a different post who was told to press "Set as StartUp Project" at the name of the project.
Other than that, I don't really know where to look for the answer. I've searched around the net, but couldn't find anything.
I hope you can help.
You have to build your project first, then start debugging.
If you don't you get this message.
The problem you are facing likely is caused because you did not build the program. Try building the program by going to the Build menu (Located to the right of Project and to the left of Debug), then press build solution in the dropdown list that appears. Wait until it is finished building, and you will likely have a working program again when you start debugging. If this does not work, you may have a bug with visual studio, in which case you must restart. If none of the above works for you, your best solution would be creating a new program and pasting the code from the old program into the new one.
I use Eclipse with CDT plugin for my C/C++ development. And I use MinGW compiler. Environment Path set properly. All the setting done properly in Eclipse. While editing the source code its working fine but after compilation when I try to execute the source code sometimes it says it cannot open the .exe file or sometimes doesn't show anything when there is some input to take. When I stop the execution pressing the red button program gets executed completely with default values.
But everything is fine if I compile and run the same source code using notepad and the command prompt. Please help.
A common problem is that if the program is currently executing, the program file is opened by the system and cannot be reopened for writing by the compiler (or more exactly by the linker). This problem can be easily reproduced by starting the program in debug mode and stop it at a breakpoint. Then, while the process is active, change a line in source and ask for a new build: you will get the error saying that the exe file cannot be opened.
How to fix: ensure to close any possible execution of the program when the error happens and rebuild
During a long compilation with Visual Studio 2005 (version 8.0.50727.762), I sometimes get the following error in several files in some project:
fatal error C1033: cannot open program database 'v:\temp\apprtctest\win32\release\vc80.pdb'
(The file mentioned is either vc80.pdb or vc80.idb in the project's temp dir.)
The next build of the same project succeeds. There is no other Visual Studio open that might access the same files.
This is a serious problem because it makes nightly compilation impossible.
It is possible that an antivirus or a similar program is touching the pdb file on write - an antivirus is the most likely suspect in this scenario. I'm afraid that I can only give you some general pointers, based on my past experience in setting nightly builds in our shop. Some of these may sound trivial, but I'm including them for the sake of completion.
First and foremost: make sure you start up with a clean slate. That is, force-delete the output directory of the build before you start your nightly.
If you have an antivirus, antispyware or other such programs on your nightly machine, consider removing them. If that's not an option, add your obj folder to the exclusion list of the program.
(optional) Consider using tools such as VCBuild or MSBuild as part of your nightly. I think it's better to use MSBuild if you're on a multicore machine. We use IncrediBuild for nightlies and MSBuild for releases, and never encountered the problem you describe.
If nothing else works, you can schedule a watchdog script a few hours after the build starts and check its status; if the build fails, the watchdog should restart it. This is an ugly hack, but it's better than nothing.
We've seen this a lot at my site too. This explanation, from Peter Kaufmann, seems to be the most plausible based on our setup:
When building a solution in Visual Studio 2005, you get errors like fatal error C1033: cannot open program database 'xxx\debug\vc80.pdb'. However, when running the build for a second time, it usually succeeds.
Reason: It's possible that two projects in the solution are writing their outputs to the same directory (e.g. 'xxx\debug'). If the maximum number of parallel project builds setting in Tools - Options, Projects and Solutions - Bild and Run is set to a value greater than 1, this means that two compiler threads could be trying to access the same files simultaneously, resulting in a file sharing conflict.
Solution: Check your project's settings and make sure no two projects are using the same directory for output, target or any kind of intermediate files. Or set the maximum number of parallel project builds setting to 1 for a quick workaround. I experienced this very problem while using the VS project files that came with the CLAPACK library.
UPDATE: There is a chance that Tortoise SVN accesses 'vc80.pdb', even if the file is not under versioning control, which could also result in the error described above (thanks to Liana for reporting this). However, I cannot confirm this, as I couldn't reproduce the problem after making sure different output directories are used for all projects.
Switch the debug info to C7 format instead of using the PDB.
Project Options -> C/C++ -> General -> Debug Information Format and set it to C7.
This generally happens when your previous attempts at debugging have not killed the debugger fully.
In Task manager look for a process called vcjit, kill it and try again.
Worst option restart visual studio, this should solve your problem.
I had this problem today and it turned out to be non-ansi characters in the path to the pdb that caused it.
I'm using windows through vmware, and my project was in a shared location: \vmware-host\Shared Folders\project
When I moved it to \Users\julian\project it resolved the issue.
I just ran into this problem. Visual studio was complaining about not being able to open vc100.pdb. I looked for open file handles to this file using procexp and found out that the process mspdbsrv had an open file handle to it. Killing this process fixed the issue and I was able to compile.
Try right click the excutable file of VS....and Properties->Compatibility-> Tick "Run this program in compatibilty mode for:" OFF........
I had a similar problem while working on a project which I had located in my Dropbox folder. I found that it would throw this error when the little "syncing" icon was going on the Dropbox icon in the system tray, since Dropbox was accessing the files to upload them to their server. When I waited to build until Dropbox finished syncing, it worked every time.
I have same problem C1033: cannot open program database,
Scenario
I have two dll's parent.dll and child.dll.I just attached child.dll project with visual studio debugger at the same time i am trying to build the parent.dll project,produces error C1033: cannot open program database
Solution
Stop debugging and kill the process attached with the debugger.Rebuild the project
This happens to me consistently if I Ctrl+Break to cancel a build (vs2015). There's some process that isn't shut down properly. I went on a rampage "End Tasking" ms/vs related processes (look for duplicates) and my build worked again. A restart would probably work too. As would moving to gnu binutils.
Annoyingly unlocker tools don't report any processes locking the file, windows doesn't let me delete the .pdb but I can rename it. My guess is two processes jump in at the same time during a build.
Are you using LinqToSql at all? Perhaps it is similar to the odd error I will experience occasionally as I asked in this question: What causes Visual Studio to fail to load an assembly incorrectly?
I changed my intermediate directory from:
%TEMP%\$(ProjectName)\$(Platform)\$(Configuration)\
to
C:\temp\$(ProjectName)\$(Platform)\$(Configuration)\
It works now. NO idea why.
In my case the problem was Google Drive: I forgot that the project was under a synced folder and G Drive probably locked that file. Pausing the sync didn't help since the error was throwed anyway.
Moving the project folder to another location not synced by Google Drive solved my issue.
Just to mention, at the beginning I thought it was my anti-virus, since when examinating the file using procexp it showed that the file was used by one of my anti-virus process. Excluding the folder project from my anti-virus scan didn't help in my case.
the simplest solution is "build one more time":
BuildConsole abc.sln /rebuild /cfg="release|Win32"
if %errorlevel% neq 0 (
BuildConsole abc.sln /cfg="release|Win32"
if %errorlevel% neq 0 (
rem process error
exit 1
)
)
I just ran into this problem and Google led me here. For me, it was Google Drive syncing my project files while I'm trying to run. Pausing Google Drive sync temporarily solved it, but I'd rather there was a way for Google Drive to keep its hands off while Visual Studio is doing its stuff. If anyone knows how I can configure that, please let me know
Basically, yesterday I could program in C++ and today I cannot.
I'm trying to write a simple hello world program in Eclipse Helios using the MinGW C/C++ compiler and I'm running into several problems, and I believe this one to be the root of it.
At first the program compiled and built, but when I tried to run it, an error dialogue said the FirstProject.exe file could not be found/does not exist in the launch configuration. However, I got no errors building and I could clearly see the binaries in Debug/FirstProject.exe in my project explorer. I tried refreshing my project explorer and alas, the file disappeared before my eyes.
I tried building the program again, and that's when I get this error:
c:/mingw/bin/../lib/gcc/mingw32/4.6.1/../../../../mingw32/bin/ld.exe: final link failed: No space left on device
I don't know what device it's talking about. I have more than 1TB left on this hard drive, so it can't be that. I tried emptying my %Temp% folder and recycling bin (suggestions I found trying to search for a solution for this problem) but to no avail.
It may be worth noting that C++ programs I have written in the past are still running. I'm very new to programming, so I don't know how much information you need, but I'll gladly add anything you need if you think you can help me out.
I just solved this on one of the computers at work which had the same issue when compiling through Codelite. Moving workspaces, rebooting, and reinstalling Codelite didn't fix the problem. I also checked permissions on the /temp folder which were fine.
It turns out there were permission issues/other issues with the disk. Running a disk check fixed a few issues on the disk and that allowed the program to compile. If this doesn't solve your issue you may also want to try disabling any anti-virus/spyware programs and try again.
I just solved this problem on my PC. Actually what the problem in my case was that my windows defender (or any antivirus in someone's case) was blocking ld.exe from accessing the protected folder that is the source code folder. You can correct this by going into the Virus and threat protection settings of your PC and then find there for blocked history. You will definitely find there a history record of that blockage. Then just go and allow on this device it. And boom 😁
I am using Eclipse with C++. When I run the program, I get the following message in my Console window:
**** Build of configuration Debug for project Disks Repulsion ****
**** Internal Builder is used for build ****
Nothing to build for Disks Repulsion
I makes changes to the program and run it again, and this time I get following message:
**** Build of configuration Debug for project Disks Repulsion ****
**** Internal Builder is used for build ****
g++ -oDisksRepulsion.exe DisksRepulsion.o -lopengl32 -lglu32 -lglut32
C:\MinGW\bin..\lib\gcc\mingw32\3.4.5........\mingw32\bin\ld.exe: cannot open output file DisksRepulsion.exe: Permission denied
collect2: ld returned 1 exit status
Build error occurred, build is stopped
Time consumed: 103 ms.
When I first ran the program, it started my program (I can see it running in my Window Task Manager), but there is no output being sent to the console.
After making changes to my program, the program is still running in the background, so I get the "Permission denied" error, when I try to run the program. I can make the error go away by ending the instances via task manager. However, when I run the program, I still don't see any output being sent to the console.
Yesterday, I was able to see the output in my console, but don't know why I cannot see it today. Also, when I saw my output, the cursor's focus did not change from the code to the console. I dislike having to do it manually.
I also don't like that when I make changes to my program, and run it again, that the program is not automatically terminated on its own.
I have used VC++ and I prefer the window Dos for output. So, I wanted to know if there is anyway in Eclipse to send the output to Windows Command Prompt, since I know that the instance of the .exe is really gone when I close the program. It automatically gets cursor's focus. I will also be able to get some output.
I installed MinGW with MaSYS or something, to compile the program.
It sounds like your application isn't terminating on its own and you didn't build in any sort of interface that would allow you to kill the program. This sounds like a bug in your code and not an Eclipse issue. If issuing a Ctrl+C in the console won't kill your program, then look into coding something that will let you kill your app with keystroke or input sequence.
If you want to run your app in a command console, then open a normal command console, browse to the folder containing your project, and run the compiled executable from the console instead of doing it through the Eclipse interface.
A simple solution, which I've been using for ages now, is opening a command prompt yourself and running the executable manually. An advantage of this method is that you can set your "DOS" window's size to anything you want. (Right now I'm using a 120x50 window with 8192 lines of scrollback buffer.) Another one is that you will never lose your console output; in fact, you'll be able to see outputs from past runs. (8192 lines is A LOT unless you're printf-debugging a tight loop.)
An alternative to terminating your program from the taskbar is using the red icons on the top right corner of the Eclipse "Console" window.
Is your program's entrypoint main() or WinMain()? There may also be a setting/link option for the "subsystem," console or Windows I think they're called in Visual Studio.
Anyway, if your program is starting up via WinMain, the expectation is that you'll have a Windows form of some sort through which the user can control the program. If you use main(), then your program should automatically trigger the opening of a console window.
Look up AllocConsole() on MSDN (or google it) if you are using WinMain() intentionally and want a console window to also open up. There's some trickery also available via google search that can hook stdout to this console, but at this time I don't remember what it is. (You basically redirect the stdout handle to your new console.)
Good luck.
