glfw-3.3.5 – Undefined symbols for architecture arm64

  apple-m1, arm64, c++, glew

Having linked all the libraries in cmake and wrtten code that’d open a window with GLFW, running build with the make command returns such output:

A thing to be noted is that it builds successfully with only the imports, but not the code responsible for opening a GLFW window, so it doesn’t seem to be a problem with the linker.

My CMakeLists.txt looks like this:

cmake_minimum_required(VERSION 3.12)
project(Game VERSION 1.0.0)
include_directories(${PROJECT_SOURCE_DIR}/deps/glfw-3.3.5/include/GLFW)
#---------------Configure dependency directories--------------------------------------------------------------
SET (PROJECT_DEPS "${PROJECT_SOURCE_DIR}/deps")
SET (glew_inc "${PROJECT_DEPS}/glew-2.1.0/include/GL/")
SET (glew_src "${PROJECT_DEPS}/glew-2.1.0/src/")
SET (glfw_inc "${PROJECT_DEPS}/glfw-3.3.5/include/GLFW/")
SET (glfw_src "${PROJECT_DEPS}/glfw-3.3.5/src/")
SET (glm "${PROJECT_DEPS}/glm/glm/")
#---------------Configure libraries----------------------------------------------------------------------------
include_directories(
    ${PROJECT_SOURCE_DIR}
    ${PROJECT_BINARY_DIR}
    ${glm}
    ${glew_inc}
    ${glew_src}
    ${glfw_inc}
    ${glfw_src}
    ${PROJECT_SOURCE_DIR}
    )
#---------------Add executable---------------------------------------------------------------------------------
add_executable(game ${PROJECT_SOURCE_DIR}/main.cpp)
link_libraries(Game PRIVATE glfw-3.3.5)
link_libraries(Game PRIVATE glew-2.1.0)
link_libraries(Game PRIVATE glm)

And my main.cpp project root file, from which the executable is built looks like this:

#include <stdio.h>
#include <stdlib.h>
#include <glew.h>
#include <glfw3native.h>
#include <glfw3.h>
#include <glm.hpp>

int main () {
  glewExperimental = true; // Needed for core profile
  if (!glfwInit()) {
      fprintf(stderr, "Failed to initialize GLFWn");
      return -1;
  }

  glfwWindowHint(GLFW_SAMPLES, 4); // 4x antialiasing
  glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3); // We want OpenGL 3.3
  glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
  glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE); // To make MacOS happy; should not be needed
  glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE); // We don't want the old OpenGL 

  GLFWwindow* window; // (In the accompanying source code, this variable is global for simplicity)
  window = glfwCreateWindow( 1024, 768, "Tutorial 01", NULL, NULL);
  if( window == NULL ){
      fprintf( stderr, "Failed to open GLFW window. If you have an Intel GPU, they are not 3.3 compatible. Try the 2.1 version of the tutorials.n" );
      glfwTerminate();
      return -1;
  }
  glfwMakeContextCurrent(window); // Initialize GLEW
  glewExperimental=true; // Needed in core profile
  if (glewInit() != GLEW_OK) {
      fprintf(stderr, "Failed to initialize GLEWn");
      return -1;
  }

  glfwSetInputMode(window, GLFW_STICKY_KEYS, GL_TRUE);

  do {
      glClear( GL_COLOR_BUFFER_BIT );
      glfwSwapBuffers(window);
      glfwPollEvents();

  } while (glfwGetKey(window, GLFW_KEY_ESCAPE) != GLFW_PRESS && glfwWindowShouldClose(window) == 0);

  return 0;  
}

I am using a MacBook Pro 2020 with a M1 chip.
