Author Topic: LNK1104 Error (Read 8583 times)

So I am trying to learn SFML and I am understanding the code, but am having troubles compiling and running any programs.

I downloaded the simple window tutorial C++ file and linked it to the sfml-window.lib file, as the tutorial on the site said, but when I went to build the program I got the following error: "LINK : fatal error LNK1104: cannot open file 'sfml-window.lib'" Which I understand means that it cannot even find the sfml-window.lib file. I installed SFML how I was told to by the tutorial and I also did the Linker/Input thing how it said, but I keep getting this error.

I don't know if I should shuffle the files around to a different spot or if I'm not doing the Linker/Input thing right, but I am baffled as to how I can fix this error.

And your sure you put the files in the right places within your compiler?

System, EDI, compiler ?

Windows XP, Microsoft Visual C++ Express Edition.

And I am sure I installed it right, as it recognizes the sf:: codes. I took the folders from the zip I downloaded and put the proper folders with their contents into my VC and include file as I was told. That is, I did not remove the files from the folders in the zip, just moved the folder and all.

*note* just because you can access sf:: (When you include the header) doesnt mean it is installed properly. Includes are only half of what you need. Try making sure that you are putting the /lib/ files into your compilers /lib/ folder.

I moved the /lib files around and now it builds successfully. Thanks all!

But now a new problem arises. Upon the launching of the program, the console crashes and I get the error: "This application has failed to start because sfml-window.dll was not found. Re-installing the application may fix the problem."

Does that mean I need to move the .dll file to my project folder? And if so where?

Yes. Or into windows/system32. But if you choose the latter possibility, don't forget to think of delivering the DLLs in your executable's directory when you want applications to work on other systems.

Into the project folder.

If you see the .vcproj and .ncb files, you're right. It's neither of the subdirectories Release or Debug, even if the .exe file is located there.

I feel so stupid. It still won't work and I don't know what I'm doing wrong. I have moved the dll to the same file as the cpp file and the project file, and I still get the same error. It's probably something extremely small, but for the life of me I can't get it.

You need to move the dll to the same folder as your exe.

Thank you! It works! Finally. It ran into an error and crashed, but I'm pretty sure that's due to it not being a complete code so I'm not worried about that part at all.

If you start the application from the MSVC++ IDE, the DLL is required in the project directory, not the one of the executable. Otherwise (if you start it directly from windows explorer), it is advisable to move the .exe to the project directory because of other dependencies like resources.

Thats not true. The exe needs the DLL to work. It doesnt matter what folder the exe is in, as long as it has the DLL to load.

Ah, you're right. But during the development, it doesn't make a lot of sense to put the DLLs into the exe folder because you have to duplicate them like this (once for Release and once for Debug). Placing them into the project directory is perfectly ok when starting from the IDE. Otherwise, rather move the .exe instead of other files, since additional dependencies like images or sounds are normally located relative to the project directory, too.
