我一直在尝试使用 glfw3 和 GLAD 为 OpenGL 建立构建环境。我目前正在使用带有 X 服务器的 WSL2 Ubuntu 进行编译和生成文件。
但是,当我运行我的 make 时,我收到以下错误:
src/glad.c:25:10:致命错误:glad/glad.h:没有这样的文件或目录 25 | #include <高兴/高兴.h>
这对我来说很奇怪,因为 makefile 似乎能够编译 main.cpp 文件并创建一个 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
这是我的制作文件:
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

int main() {

glfwInit();
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);

glfwTerminate();
return -1;

glfwPollEvents();
