网上参考的资料有很多，但是多数没有涉及到GLtools，现在终于弄好啦。 开心，可以进一步学习啦。
工具环境：macOS Mojave Clion
配置过程：
1.安装 homebrew（已安装可跳过）
homebrew 的官方网站: http://brew.sh/
在 Mac 中打开 Termal 并输入以下命令进行安装 homebrew：
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
2.利用homebrew安装glew和glfw3
brew install glew
brew install glfw3
3.利用homebrew安装cmake
brew install cmake
4. 编译 gltools
依次执行以下命令：
$ git clonehttps://github.com/HazimGazov/GLTools
$ cd GLTools
$ cmake
$ make
$ sudo make install
5. 配置Clion的CMakeLists.txt
我的配置为：
cmake_minimum_required(VERSION 3.13)
project(untitled1)
set(CMAKE_CXX_STANDARD 11)
# 添加头文件
set(GLEW_H /usr/local/Cellar/glew/2.1.0/include/GL)
set(GLFW_H /usr/local/Cellar/glfw/3.3/include/GLFW)
set(GLTOOLS_H /usr/local/include)
include_directories(${GLEW_H} ${GLFW_H} ${GLTOOLS_H})
# 添加目标链接
set(GLEW_LINK /usr/local/Cellar/glew/2.1.0/lib/libGLEW.2.1.dylib)
set(GLFW_LINK /usr/local/Cellar/glfw/3.3/lib/libglfw.3.dylib)
set(GLTOOLS_LINK /usr/local/lib/libgltools.dylib)
link_libraries(${OPENGL} ${GLEW_LINK} ${GLFW_LINK} ${GLTOOLS_LINK})
#执行编译命令
set(SOURCE_FILES main.cpp)
add_executable(untitled1 ${SOURCE_FILES})
if (APPLE)
target_link_libraries(untitled1 "-framework OpenGL")
target_link_libraries(untitled1 "-framework GLUT")
endif()
注意，其中的untitled1是我的项目名，你需要改成自己的。Reload CMake后没报错即成功。
6. 测试
测试代码为：
#include <GLTools.h>
#include <GLShaderManager.h> // Shader Manager Class
#ifdef __APPLE__
#include <glut/glut.h> // OS X version of GLUT
#else
#define FREEGLUT_STATIC
#include <GL/glut.h> // Windows FreeGlut equivalent
#endif
GLBatch triangleBatch;
GLShaderManager shaderManager;
void ChangeSize(int w, int h)
{
glViewport(0,0,w,h);
}
void SetupRC()
{
glClearColor(0.0f,0.0f,1.0f,1.0f);
shaderManager.InitializeStockShaders();
//Load up a triangle
GLfloat vVerts[]={-0.5,0.0f,0.0f,
0.5f,0.0f,0.0f,
0.0f,0.5f,0.0f};
triangleBatch.Begin(GL_TRIANGLES, 3);
triangleBatch.CopyVertexData3f(vVerts);
triangleBatch.End();
}
void RenderScene(void)
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT|GL_STENCIL_BUFFER_BIT);
GLfloat vRed[]={1.0f,0.0f,0.0f,1.0f};
shaderManager.UseStockShader(GLT_SHADER_IDENTITY,vRed);
triangleBatch.Draw();
glutSwapBuffers();
}
int main(int argc, char* argv[])
{
gltSetWorkingDirectory(argv[0]);
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_RGBA|GLUT_DEPTH|GLUT_STENCIL);
glutInitWindowSize(800,600);
glutCreateWindow("Triangle");
glutReshapeFunc(ChangeSize);
glutDisplayFunc(RenderScene);
GLenum err=glewInit();
if(GLEW_OK != err){
fprintf(stderr,"GLEW ERROR: %s\n", glewGetErrorString(err));
return 1;
}
SetupRC();
glutMainLoop();
return 0;
}
结果为：
