I followed this tutorial successfully. But it doesn’t explain how to configure on vscode. Glad is in this folder /usr/include and I did use sudo in the terminal to compile and generate a.out. How do I do that in vscode? I have this error output when I try to build task: terminal My tasks is configured l…

CMake C++ Project librealsense: undefined reference to OpenGL with CLion
I am trying to integrate librealsense C++ CLion Project on Ubuntu 20.04. Compiling the Librealsense separately in the terminal works just as expected. the Project looks like this: RS_Pipeline . ├── build ├── main.cpp ├── CMakeLists.txt └── librealsense // the integrated lib ├── CMakeLists.txt ├── third-party …
How does wglGetProcAddress/glXGetProcAddress communicate with a graphics driver?
When I build an OpenGL application on Windows 10 I have to link to opengl32.lib. I use GLEW for loading OpenGL functions. GLEW internally uses wglGetProcAddress(). opengl32.lib provides support only for OpenGL 1.1. How does opengl32.lib work when wglGetProcAddress() asks for some newer OpenGL functionality? D…
Opengl using freeglut on linux shows only a transparent window

I am just trying to make a black window to show on screen but only a transparent window shows up and it doesn’t close until it shows Segmentation fault (core dumped) here is my

Assimp aiString empty when compiling for Linux
I’m working on a simple OpenGL project and I’m new to C++. I’ve been slowly adding features to a very simple primitive 3D “engine” and I’ve worked to make sure it compiles cross-platform. I have a make file that I run for OSX and Linux (Ubuntu) and for Windows I have a Visu…
LWJGL – OpenGL not rendering
The following LWJGL code is expected to render a blueish square in the center of the screen. Instead, I get a blank white screen. It’s like the rendering is not working at all, or that I am rendering outside of the screen. I’m a complete noob in OpenGL and LWJGL, so I’m out of my depth. I we…
How to know if an opengl function is going to block?
I am using wayland with IVI extension. I have a program, showing camera image in a sufrace, and it is controlled using dbus. I found out that if the surface is hidden, then the opengl functions are blocking the program (It is glClear( GL_COLOR_BUFFER_BIT ); which blocks). I found this discussion, which explai…
Can not compile shaders with Linux/Mesa
I have a OpenGL 3.0 application which works well when it is used with Windows. My shader programs all start with Now when I stwich over to linux with OpenGL 3.0 Mesa 18.0.5, compiling of these shaders fails with error message What could be the problem here? It is definitely OpenGL 3.0 which should support GLS…

I’m trying to build the OpenGL Super Bible 7th edition code samples on Ubuntu 16.04. First I have to run cmake, which seems to work, and then I have to run make to compile. I believe I have installed glfw3 and the Mesa OpenGL packages. When I execute cmake (after installing libglfw3 and libglfw3-dev), I…
