如何让 macbook pro 识别 GLEW 和 GLFW？

Question

我一般是 macbook 和苹果电脑的新手，所以我很难让 macbook pro 识别 GLEW 和 GLFW。我安装了两个库都没有问题，我的包含如下：glew.h、glxew.h 和 wglew.h 的 /usr/include/GL。 /usr/lib/ 包含 libGLEW.a GLFW 的包含和 lib 文件位于 /usr/local/ 我使用 vim 作为文本编辑器并有一个简单的 main.cpp 程序，但它给了我一个错误，即 glew.h找不到，任何想法为什么会发生这种情况以及我应该如何解决它？

#include <GL/glew.h>

#define GLFW_DLL
#include <GLFW/glfw3.h>

#include <stdio.h>

int main()
{
  if (!glfwInit())
  {
    fprintf (stderr, "ERROR: could not start GLFW\n");
    return 1;
  }

  glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
  glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 2);
  glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
  glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

  GLFWwindow* window = glfwCreateWindow (640, 480, "Hello Shaders", NULL, NULL);
  if (!window)
  {   fprintf(stderr, "ERROR: could not openwindow with GLFW3\n");
    glgwTerminate();
    return 1;
  }
  glfwMakeContextCurrent (window);

  glewExperimantal = GL_TRUE;
  glewInit();

  const GLubyte* renderer = glGetString(GL_RENDERER);
  const GLubyte* version = glGetString(GL_VERSION);
  printf("Renderer: %s\n", renderer);
  printf("OpenGL version supported %s\n", version);

  glEnable (DEPTH_TEST);
  glDepthFunc (GL_LESS);

  glfwTerminate();

  return 0;
}

我正在编译：

g++ -framework Cocoa -framework OpenGL -framework IOKit -o demo main.cpp -I include -I/sw/include -I/usr/local/include /usr/lib/libGLEW.a /usr/local/lib/libglfw3.a

编辑：将 GL 包括移动到 /usr/local 修复了编译错误，但现在我收到链接器错误，知道可以在这里做什么吗？

Answer 1

如果您收到与包含头文件相关的错误，则编译器找不到头文件。您可以将-v 标志传递给GCC（包括g++）或Clang（包括clang++）以查看有关它在哪里寻找它的信息。

正如this forum post 解释的那样，如果您收到这些链接错误：

Undefined symbols for architecture x86_64:
  "_CVDisplayLinkCreateWithCGDisplay", referenced from:
      __glfwPlatformGetVideoModes in libglfw3.a(cocoa_monitor.m.o)

那么你可能需要链接CoreVideo 框架。如果是在命令行编译，可以使用-framework CoreVideo。
