Title: "Undefined reference to" error when I build my game.
Post by: SkeleDotCpp on December 28, 2017, 09:44:29 pm

When I run my game, I get these errors:

Quote

This is the code that causes this:

sf::SoundBuffer rifleShotBuffer;
if (!rifleShotBuffer.loadFromFile("Audio/RifleShot.wav")) {
   return EXIT_FAILURE;
}
 

Can someone explain why this happens?

Sounds like you didn't link the libraries in the right order. It should always be X depends on Y, the X needs to be specified before Y.
sfml-audio depends on sfml-system...

This is how I linked my libraries:

Quote

sfml-graphics-s
(All dependencies for graphics)
sfml-window-s
(All dependencies for window)
sfml-system-s
(All dependencies for system)
sfml-audio-s
(All dependencies for audio)

Is this the right order?

No, read again or read the official tutorial

I have re checked and fixed the issue with the order. Thank you :)
