)': Visual C++ & SFML compilation problems! :'(

Hi all,

After having followed the SFML tutorial on the website ( www.sfml-dev.org ) & successfully running their clock sample I decided to try my luck at compiling one of the sample programs included in the SFML download bundle.
However, my luck ran out when compiling the Window sample program & the build log says:

Code:

---

1>------ Build started: Project: pong, Configuration: Debug Win32 ------
1>sfml-graphics.dll : fatal error LNK1107: invalid or corrupt file: cannot read at 0x2B0
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

If you have any ideas how I can get around this I'd be very grateful! The file cannot be corrupt since I literally just downloaded it & have made no changes!

Are you using the correct version of the binary files for your version of Visual C++.
They must match because Microsoft C++ DLLs are not compatible with each other.
VS 2008 C++ DLLs do not work with VS 2005 compilers.

What is your version of Visual C++?

Tim S.

I'm using Visual Studio 2010 Express C++ edition, the SFML tutorial said it's compatible.

Are you using any Binary files from the web-site?

Tim S.

I'm not sure, but I don't think so! I've literally followed the steps in the tutorial!

Code:

---

Copy the *.lib files in SFML-x.y\lib to the VC\lib directory of your Visual Studio installation

---

FYI: Library files are binary files.
C++ Libraries are NOT necessary compatible with different versions of the same compiler.

Tim S.

Ooops I didn't realise, I thought binary files could only end .bin :-S

I've copied those files in anyway! ^^

I think the problem may have something to do with the project's Linker > Input > Additional dependencies.

When I add or remove one or both of the sfml-graphics-d.dll & sfml-graphics.dll parameters from the field I get different errors depending which I take out!

Hope this helps! ^^

You want sfml-graphics-d.lib or sfml-graphics.lib in the Additional Dependencies. Lib files are bits the linker uses, dll files are bits your program uses.

After implementing that change I get this error instead:

Code:

After including all of the SFML.lib & SFML-d.lib files to the additional dependencies field AND adding all of the SFML.lib & SFML-d.lib files to the program's directory I'm still getting this error:

Code:

---

1>------ Build started: Project: pong, Configuration: Debug Win32 ------

As was mentioned earlier, the binaries provided by SFML don't work in Visual Studio 2010. Assuming you are using 1.6, I have libraries compiled for Visual Studio 2010 available here. Once you have them downloaded, read this guide which goes into extreme detail on how to setup Visual C++ Express 2010 to work with SFML. If that fails, at the end there is a preconfigured but empty project you can simply download, unzip and go from there. If you are using SFML 2.0, VS 2010 binaries are available at the bottom of this post ( which coincidentally is about how to build SFML 2.0 ). The directions I linked earlier should work for you unchanged regardless to which version you are using.


Why oh why they don't provide pre-compiled binaries for VS2010 even though it's what 99% of people use these days, I just don't know. It would massively cut down on support incidents on the sfml website and would make things a ton easier for new developers.


Try the above, and if it doesn't work, try the pre-configured project. If that still doesn't work, let me know and I will see if I can help.

Thanks Serapth!

Game From Scratch has been really helpful! Thanks so much for your advice!!!
