If anyone with a modern (post-2010 or so) machine has trouble starting sdrangel on Windows 10, the first thing they probably ought to do, is to try to upgrade their display driver (and barring that, the video card). sudo apt install binutils-gold g++ cmakelibglew-dev g++ mesa-common-dev build-essential libglew1.5. It definitely would not seem to require 4.4 or 4.5 however. Step 1: To create OpenGL development environment we need to get some necessary libraries including freeglut so, Open Terminal and enter the following commands: sudo apt update. Unfortunately it seems like "it depends" is probably the right answer, but sdrangel definitely seems to be dependent upon some functionality added to OpenGL after 4.0. This driver shows up in GLView OpenGL Extensions Viewer as being 100 percent compatible with 4.0, and partially compatible with 4.1, 4.2, 4.3 and 4.4 (it scores as 80% + compatible with 4.2 and lower for 4.3 and higher). However, when I switch to the newer build of the driver (, 10.), sdrangel will run. Note that it is 100 percent compatible with OpenGL 4.0 and lower, but zero compatible with higher. I find that sdrangel 3.8.5 does not work when I have this version of my graphics card driver installed:Īccording to GLView OpenGL Extensions Viewer, the OpenGL version is 4.0. Make sure to first identify your Intel Graphics Controller. Intel Graphics controllers support a wide range of APIs. I thought I would share my own experience as it may bear on this issue. PC games and applications often require a video card that is compatible with specific Application Programming Interfaces (APIs), such as OpenGL, DirectX, OpenCL, or Vulkan.
