Ubuntu install OpenGL development environment

apt install link library

sudo apt-get install build-essential libgl1-mesa-dev
sudo apt-get install freeglut3-dev
sudo apt-get install libglew-dev libsdl2-dev libsdl2-image-dev libglm-dev libfreetype6-dev

Use OpenGL

Write a simple to use OpenGL libraries cpp files need only# include <GL/glut.h>

# include <GL/glut.h>
# include <stdlib.h>

Save as test.cpp
in compiling terminal

g++ test.cpp -o test -lgl -lglut

-L command behind the past rarely used, because not used dynamic libraries. -l + dynamic library name, indicating a link in the link library, the equivalent of adding dll

-lgl is linked to the gl library
-lglut is linked to the glut library
can be executed

IDE Configuration

In CLion in a new project, and copy the code just written into main.cpp
edit CMakeLists.txt, add a link library.

make_minimum_required(VERSION 3.6)
 project(HelloOpenGL)
 set(CMAKE_CXX_STANDARD 11)
 
 set(SOURCE_FILES main.cpp)
 set(TARGET_LIB
     "/usr/lib/x86_64-linux-gnu/libGL.so"
     "/usr/lib/x86_64-linux-gnu/libGLU.so"
     "/usr/lib/x86_64-linux-gnu/libglut.so"
     )
 add_executable(HelloOpenGL ${SOURCE_FILES})
 target_link_libraries(HelloOpenGL ${TARGET_LIB})
 

Run Setup configuration, run the program
