Can't play audio with STATIC linked SFML - c++

Question

I am making a simple Pong game and after finishing the game I tried to add a sound effect for the ball collision but the compiler would not compile the code and send some errors I made sure that openal32 is linked and the .dll is in the directory of the project. So I would write the whole game without a problem and as soon as I include
buf.loadFromFile("data\pong.wav");
Sound sound;
sound.setBuffer(buf);
The compiler won't even start the game and would give me those errors,I am using SFML 2.5.1 after compiling it for visual studio 2019 that I am using.

Answer 1

I think you used the wrong compiler. As SFML depends on a big number of underlying libraries (flac.lib is only one example..). These libraries are part of the download. However these libraries need to be used with the same compiler they were build.
That is why SFML is offering Downloads for different visual studio versions.
Between the versions Microsoft changed header definitions so now functions are defined different than in the delivered libraries(basically the header files changed between the different Visual Studio versions).
You may have success by
using the legacy_stdio_definitions.lib to resolve the issues
recompile all dependencies in your current compiler (or search for them to download)
switch back to supported Visual Studio 2015
