Closed 4 years ago.
I've been trying to compile C++ code and dont reliant on IDE recently,
and I decided to use an editor and command line to write and compile code.
And the problem is I want to make a glfw app but I get an error when I linking with glfw3.lib and opengl32.lib:
a.exe : fatal error LNK1120: 92 unresolved externals
os: Windows 7
compiler: clang
src/main.cpp:
#include <stdlib.h>

#include "window.h"
#define WIDTH 800
#define HEIGHT 600
int main(int argc, char* argv[]){
if (!Window_init(WIDTH, HEIGHT, "HELLOWORLD")){
printf("Problem loading window!\n");
return 1;
}
return 0;
}
src/window.h

int Window_init(int width, int height, char* title){
if (!glfwInit())return 0;
glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);
window = glfwCreateWindow(width, height, title,NULL, NULL);
if (!window){
return 0;
}
glfwMakeContextCurrent(window);
return 1;
}
void Window_update(){
}
#endif // !WINDOW_H

Answer 1

Lets demonstrate you the algorithm.
Let we see __imp__GetRawInputDeviceInfoA between unresolved symbols.
Google GetRawInputDeviceInfoA.
First page in results is https://msdn.microsoft.com/en-us/library/windows/desktop/ms645597(v=vs.85).aspx
Open and scroll the page to the bottom. We see there | Library | User32.lib |.
Add the library to the command line: clang++ ..\src\*.cpp -L..\lib -lglfw3 -lopengl32 -I..\include\ -std=c++17 User32.lib
Try to build.
Repeat from 1 till 6 until all unresolved symbols are fixed.
Remove ..\src\*.h from the command line.
