Question

I've created a new C++ project in Visual Studio 2008. No code has been written yet; Only project settings have been changed.

When I compile the project, I receive the following fatal error:

fatal error LNK1104: cannot open file 'C:\Program.obj'

Was it helpful?

Solution

This particular issue is caused by specifying a dependency to a lib file that had spaces in its path. The path needs to be surrounded by quotes for the project to compile correctly.

On the Configuration Properties -> Linker -> Input tab of the project’s properties, there is an Additional Dependencies property. This issue was fixed by changing this property from:

C:\Program Files\sofware sdk\lib\library.lib

To:

" C:\Program Files\sofware sdk\lib\library.lib"

Where I added the quotes.

OTHER TIPS

This can happen if the file is still running as well.

:-1: error: LNK1104: cannot open file 'debug\****.exe'

The problem went away for me after closing and re-opening Visual Studio. Not sure why the problem happened, but that might be worth a shot.

This was on VS 2013 Ultimate, Windows 8.1.

Check also that you don't have this turned on: Configuration Properties -> C/C++ -> Preprocessor -> Preprocess to a File.

I had the same problem.It caused by a "," in the name of a folder of additional library path.It solved by changing the additional library path.

My problem was a missing .lib extension, I was just linking against mylib and VS decided to look for mylib.obj.

In my case it was a matter of a mis-directed reference. Project referenced the output of another project but the latter did not output the file where the former was looking for.

For an assembly project (ProjectName -> Build Dependencies -> Build Customizations -> masm (selected)), setting Generate Preprocessed Source Listing to True caused the problem for me too, clearing the setting fixed it. VS2013 here.

I run into the same problem with linker complaining about the main executable missing. This happened during our solution port to the new Visual Studio 2013. The solution is a varied mix of managed and un-managed projects/code. The problem (and fix) ended up being a missing app.config file in the solution folder. Took a day to figure this one out :(, as output log was not very helpful.

I checked all my settings according to this list: http://msdn.microsoft.com/en-us/library/ts7eyw4s.aspx#feedback . It is helpful to me and for my situation, I find out that Link Dependency of projects' properties has double-quote, which should not be there.

I had the same error, just with a Nuget package i had installed (one that is not header only) and then tried to uninstall.
What was wrong for me was that i was still including a header for the package i just uninstalled in one of my .cpp files (pretty silly, yes).
I even removed the additional library directories link to it in Project -> Properties -> Linker -> General, but of course to no avail since i was still trying to reference the non-existent header.

Definitely a confusing error message in this case, since the header name was <boost/filesystem.hpp> but the error gave me "cannot open file 'llibboost_filesystem-vc140-mt-gd-1_59.lib'" and no line numbers or anything.

I had the same problem, but solution for my case is not listed in answers. My antivirus program (AVG) determined file MyProg.exe as a virus and put it into the 'virus storehouse'. You need to check this storehouse and if file is there - then just restore it. It helped me out.

Solution 1 (for my case): restart windows Explorer process (yes, the windows file manager).

Solution 2:

  1. Close Visual Studio. Windows Logoff
  2. Logon, reopen Visual Studio
  3. Build as usual. It now builds and can access the problematic file.

I presume sometimes the file system or whoever is controlling it gets lost with its permissions. Before restarting the windows session, tried to kill zombie msbuild32.exe processes, restart visual studio, check none even showing the problem file on. No build configuration issues. It happens now and then. Some internal thing in Windows does not fix up, needs a restart.

I'm answering because I don't see this particular solution listed by anyone else.

Apparently my antivirus (Ad-Aware) was flagging a DLL one of my projects depends on, and deleting it. Even after excluding the directory where the DLL lives, the same behaviour continued until I restarted my computer.

In my case, I had replaced math library files from a previous Game Engine Graphics course with GLM. The problem was that I didn't add them to the project within Visual Studio's Solution Explorer (even though they were in the project repository).

I had this issue in conjunction with the LNK2038 error, followed this post to segregate the RELEASE and the DEBUG DLLs. In this process I had cleaned up the whole folder where these dependencies were residing.

Luckily I had a backup of all these files, and got the file for which this error was throwing back into the DEBUG folder to resolve the issue. The error code was misleading in some way as I had to spend a lot of time to come to this tip from one of the answers from this post again.

Hope this answer, helps someone in need.

I solved it by adding an existing project to my solution, which I forgot to add in the first time.

I had the same error: 

fatal error LNK1104: cannot open file 'GTest.lib;'

This was caused by the ; at the end. If you have multiple libraries, they should be separated by empty space (spacebar), no comma or semi-colons!

So don't use ; or any anything else when listing libraries in Project properties >> Configuration Properties >> Linker >> Input

I hit the same problem with "Visual Studio 2013". 

LNK1104: cannot open file 'debug\****.exe

It resolved after closing and re-starting Visual studio.

I was having the same problem , I have just copied the code to new project and started the build . Some other error started coming. error C4996: 'fopen': This function or variable may be unsafe. Consider using fopen_s instead

To solve this problem again, I have added my one property in the Project project as below. Project -> Properties -> Configuration property -> c/c++ . In this category there is field name Preprocessor Definitions I have added _CRT_SECURE_NO_WARNINGS this to solve the problem Hope it will help ...
