I've downloaded the latest version of freetype, added freetype.lib and the include folder to my project and linked everything in project properties. Is there something I'm missing?

I'm getting 7 unresolved externals:

Error    LNK2019    unresolved external symbol __imp_FT_Stream_OpenLZW referenced in function PCF_Face_Init    Wizzy-core    C:\Users\CM\Documents\SourceTree\Wizzy\WizzyEngine\Wizzy-core\freetype.lib(pcf.obj)    1

EDIT:

It actually builds fine until I call FT_Init_FreeType()

This is all the code that's related to FreeType

/******fonthandler.h******/

#pragma once
#include <ft2build.h>
#include FT_FREETYPE_H

class FontHandler {
private:
	FT_Library m_lib;
private:
	FontHandler() {}
public:
	bool Init();
};
  
/******fonthandler.cpp******/
  
#include "fonthandler.h"
#include "..\..\..\debug\debugging.h"
  
bool FontHandler::Init() {
	auto _error = FT_Init_FreeType(&m_lib);
	if (_error) {
		log("Failed to initialize FreeType...");
		log("Error: '{0}'", _error);
	}

	return !_error;
}

I would guess that the lib was build with /MT and you're using /MD. The best thing to do would be to recompile the lib with /MD and /MDd but you can check the link below for a possible quick fix as well as additional info.

Yup building the .lib file with /MD seems to fix my issues. Thanks a lot.

For future googlers: In the freetype solution you need to go to project properties -> C/C++ -> Code Generation and change "Runtime Library" from 'Multi-threaded (/MT)' to 'Multi-threaded DLL (/MD)' and just build it again and remember to grab the new freetype.lib file and replace the one that's linked to your project.
