Title: Linking error (LNK 2019) with sf::Sprite
Post by: hoenchioma on November 02, 2018, 09:58:16 pm

After working with a project for quite while now using SFML these come up.

Code: [Select]

Here Undead is a class with a constructor like,

Code: [Select]

Undead(sf::Texture *texture1, sf::Texture *texture2, sf::Texture *texture3);
It has an sf::Sprite member. This sets one of the 3 textures to the sprite member based on some internal calculations.
Then I've used a vector of it (in another class/file) and pushed versions of it like this

Code: [Select]

std::vector <Undead> zombies;
zombies.push_back(Undead(&undeadTexture1, &undeadTexture2, &undeadTexture3));

What's worse is that it compiles and runs fine on my friends computer. The same code. I've tried to mimic all configurations his VS / SFML setup has to no avail. I even re-downloaded and setup SFML.

Few things:
1. SFML version : 2.5.0
2. Visual Studio 2017
3. I've not set SFML_STATIC (I don't want or need static linking)
4. All the sfml dlls are in the folder where the .exe file is supposed to be
5. I haven't faced this issue before in SFML and I've been using SFML for quite a while now.
(provided I did not have to make a vector of objects with sf::Sprite objects as members)
6. It works fine on my friends computer (same SFML version and VS)

Try a clean and full rebuild and/or delete the generated folders and object file and rebuild.

I've also tried that. It didn't work.
