Getting error when compiling, something about the input #5

Closed ScripterStuff closed 1 year ago

I get this error when I try to compile: Severity Code Description Project File Line Suppression State Error LNK2019 unresolved external symbol "public: static class Walnut::Application & cdecl Walnut::Application::Get(void)" (?Get@Application@Walnut@@SAAEAV12@XZ) referenced in function "public: static struct glm::vec<2,float,0> cdecl Walnut::Input::GetMousePosition(void)" (?GetMousePosition@Input@Walnut@@SA?AU?$vec@$01M$0A@@glm@@XZ) RayTracing C:\Users\Student\Documents\SA RayTracing\RayTracing\RayTracing\Walnut.lib(Input.obj) 1

I don't know what to do, I haven't found anything helpful online either.

This looks like the version of the Walnut source you are linking to your project does not provide the function ?Get@Application@Walnut@@SAAEAV12@XZ (which would be declared in the source as public: static class Walnut::Application & __cdecl Walnut::Application::Get(void)). Please check if the source you are using for Walnut matches with the expected version and that the mentioned function is present there.

You may want to clean your project by removing all cached or previously built binaries to force recompilation. Sometimes such errors appear randomly when files from a previous built are mixed into linking of fresh binaries.

BTW: You can mark things as code by using backticks. That makes such long identifiers much more readable.

Thanks I just needed to update Application.cpp
