CSFML Audio - Yet Another LINK Question

CSFML - Yet Another LINK Question

Using Visual Studio Express 2013 for Windows

Hi,

I have a fairly large, legacy C language, simulation app that currently supports sound via a late 90's audio library named SEAL.  I'd like to upgrade it to CSFML Audio.
I've created a project and simple C program (below) to help me understand the features of CSFML.

I installed SFML-2.5.1 and then dropped the CSFML-2.5.1 folders on top of it, merging them together.  I (theoretically) followed Project Setup instructions for PATHs and supporting files (see screenshots below).  When I build the project, compilation is fine but I get a unresolved external symbol LINK error, also shown below.

I've played with this for many hours now and my mistake eludes me.  Does anyone have any thoughts?

Thanks!
Brad

//****** EXAMPLE CSFML PROGRAM******//
#include <SFML/Audio/Sound.h>
#include <SFML/Audio/Music.h>

static void CSFMLSoundTest(void);

int main(int argc, char* argv[])
{
   int      i = 0;

   CSFMLSoundTest();
   return;
}

void CSFMLSoundTest(void)
{
   sfMusic *TestMusic;
   TestMusic = sfMusic_createFromFile("test.wav");
}
 

Output
1>noise1.obj : error LNK2019: unresolved external symbol __imp__sfMusic_createFromFile@4 referenced in function _CSFMLSoundTest@0
1>.\Release/randomprojects1.exe : fatal error LNK1120: 1 unresolved externals

You should use a version of SFML compiled with Visual Studio 2013, which we don't provide as far as I know. In this case you'll have to compile SFML and CSFML yourself. Or upgrade to a recent Visual Studio.

Uuhhhh, best way to mess things up. They are separate self-contained libraries, don't try to mix them.

Thanks for the quick response!

Yes, I started out that way (standalone CSFML directory tree) and resorted to merging in an attempt to fix the reported problem.  I had read somewhere that is was okay to combine them since the file names were unique.  I just now "separated" CSFML from SFML, copied openal32.lib, etc. to the CSFML lib folder and the problem still exists.

Thanks!

Yes, as I said the problem is with your version of Visual Studio, don't focus on my other comment that had nothing to do with your problem ;)

My bad.  I zeroed in on your response after the "Quote" and totally missed your lead in.  Sorry!

I though SFML 2.5.1 was offered for Visual Studio 2013 (which is VC12).  I was able to take the SFML sound example code in C++ and compile, link and run it successfully.   However, I didn't realize that the CSFML 2.5 download was Visual Studio version sensitive.

Unfortunately, a newer version of Visual Studio is not currently an option for me as the one I have is (my understanding) the last to support DirectX 9.0c.

Thanks,
Brad

Ah, you're right, I should have checked before posting.

After thinking more about it, I'm not sure... you should try to recompile it and see if it solves your problem.
