glad.c 无法找到 glad/glad.h,但 main.cpp 可以

glad.c unable to find glad/glad.h, but main.cpp can

我一直在尝试使用 glfw3 和 GLAD 为 OpenGL 设置构建环境。我目前正在将 WSL2 Ubuntu 与用于编译的 X 服务器和生成文件一起使用。

但是,当我 运行 我收到以下错误:

src/glad.c:25:10: fatal error: glad/glad.h: No such file or directory 25 | #include <glad/glad.h>

这对我来说很奇怪,因为似乎 makefile 能够编译 main.cpp 文件并创建 main.o 尽管还包括“glad/glad.h”

文件结构:

-HelloTriangle
--include
---glad
----glad.h
---KHR
----khrplatform.h
--src
---glad.c
---main.cpp
--makefile

这是我的 make 文件:

BASE_OBJS = main.o glad.o

SRC_PATH = src

OBJS = $(addprefix $(SRC_PATH)/, $(BASE_OBJS))
CXX = g++
CXXFLAGS = -g -Iinclude
LDFLAGS =
LDLIBS = -lglfw -lGL -lX11 -lpthread -lXrandr -lXi -ldl

HelloTriangle: $(OBJS)
    $(CXX) -o $@ $(LDFLAGS) $^ $(LDLIBS)    

clean:
    rm $(OBJS)

这是我的 main.cpp:

#include <glad/glad.h>
#include <GLFW/glfw3.h>
#include <iostream>

#define WINDOW_WIDTH 800
#define WINDOW_HEIGHT 600

/*
Function to handle window resizing
*/
void framebuffer_size_callback(GLFWwindow* window, int width, int height);

int main() {
    /* 
    Initialize GLFW
    Sets version to Core profile 3.3
     */
    glfwInit();
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

    /* 
    Initialize a window context for OpenGL
    Defines the windows width, height, and title
     */
    GLFWwindow* window = glfwCreateWindow(WINDOW_WIDTH, WINDOW_HEIGHT, "Hello Triangle", NULL, NULL);
    if(window == NULL) {
        std::cout << "Failed to create GLFW window" <<std::endl;
        glfwTerminate();
        return -1;
    }

    /* 
    Initialize GLAD
    Handles OS-specific function pointers
    */
    if(!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress)) {
        std::cout << "Failed to initialize GLAD" << std::endl;
        return -1;
    }

    /*
    Handle window resizing
    */
    glViewport(0, 0, WINDOW_WIDTH, WINDOW_HEIGHT);
    glfwSetFramebufferSizeCallback(window, framebuffer_size_callback);

    /*
    Render loop
    */
    while(!glfwWindowShouldClose(window)) {
        glfwSwapBuffers(window);
        glfwPollEvents();
    }

    glfwTerminate();
    return 0;
}

void framebuffer_size_callback(GLFWwindow* window, int width, int height) { glViewport(0, 0, width, height); }

您似乎设置了 CXXFLAGS(针对 C++ 编译器),但您的 glad.c 是使用 C 编译器(检查 CFLAGS)编译的
