error:

CMake Error at CMakeLists.txt:18 (find_package): Could not find a package configuration file provided by "glm" with any of the following names:

glmConfig.cmake
glm-config.cmake

Add the installation prefix of "glm" to CMAKE_PREFIX_PATH or set "glm_DIR" to a directory containing one of the above files. If "glm" provides a separate development package or SDK, be sure it has been installed.

i can cmake glm package sucessfully but do not get the two cmake files below. this is in windows. not linux or mac. i am using cmake gui version.

$ ./chapter01 basic
Unable to create OpenGL context.
$./chapter02 basic-attrib
Unable to create OpenGL context.
$ ./chapter03 diffuse
Unable to create OpenGL context.

In spite of success executions (but with a segfault sometimes) of examples from the 2nd edition of this book.

Hi, the examples all work on Ubuntu 18.04 but they don't exit cleanly starting from Chapter 2. Only Chapter 1's example exits properly without any issues. When the X is clicked with the mouse or when I hit ESC, the app always segmentation faults at close. Here's the output for Chapter 2's example:

$ ./chapter02 basic-attrib

The link to "suggestions and feedback" at the bottom of the README.md is broken.

Is there anywhere else I can send suggestions/feedback? I'm getting a lot out of the book, it's proving to be a vauable resource. I would suggest a more thorough discussion of SPIRV shaders for use in OpenGL.

One of the reasons I purchased this book was because of the following on the amazon page: What you will learn

• Understand physically based reflection models and the SPIR-V Shader binary

But the discussion of SPIRV feels a little lacking, partly because in practice - getting SPIRV shaders working correctly on OpenGL is a bit of a fools errand, with support across vendors and platforms seeming to be incredibly lacking/broken.

It also makes no mention that raw uniforms are not supported, in favour of uniform buffer objects.

I just installed a new Ubuntu 18.04 operating system with Cuda 10.1 and its associated graphics driver 4.18. I have also git cloned this repository and compiled it with cmake without a hitch. I am even able to run the an executable, except that I run into the error Unable to create OpenGL context.. I have been told that old drivers cause this, but I just installed all of the newest drivers.

What should i do to fix this?

Edit:

I decided to do more investigative work on the issue and I noticed that OpenGL simply will not link properly when -lGL is passed to a command line compile option. Well, I got to thinking: are the drivers REALLY correct?

So that I searched on checking OpenGL versions.

Running

glxinfo | grep "OpenGL version"

On my machine that does work gives me this:

OpenGL version string: 4.6.0 NVIDIA 410.48

and

Running

glxinfo | grep "OpenGL version"

On my machine that does NOT work gives me this:

OpenGL version string: 3.0 Mesa 19.0.8

I know that you can have Mesa aptitude packages installed, but I somehow am still not getting NVidia to load the OpenGL context properly.

How do you force OpenGL loaders?

P.S.

I tried to compile the NVIDIA CUDA 10.1 examples right off of the home directory and the OpenGL example:

~/NVIDIA_CUDA-10.1_Samples/2_Graphics/marchingCubes

Does NOT compile. Here is the full error:

I know that only the first question is related to the book, but I think the extra context helps.

The gitignore file actually ignores the cmake directory. The CMake file now defaults to modern OpenGL on Unix machines. Before this fix CMake would tell you that 2 versions were available, but it is not clear which one is being used. The random.h file now uses correct C++17 default random number generator. Before this fix C++17 would not compile because the definition of std::shuffle no longer exists. The updated code uses a version of std::shuffle that does exist. This has been tested and solved on Ubuntu 18.04 LTS with GCC 9.x.x and CMake 3.15.2.

The ssao example in chapter06 fails to run. Because both the model files dragon.obj and bunny.obj do not exist in this repo. And there is no instruction in README to help me how I can get access to these models.
