layout(binding=0) uniform sampler2D requires `#version 420 core`

Problem:
I got this when running the bumpmapping example:

VERSION: 4.6 (Core Profile) Mesa 21.2.6
RENDERER: Mesa Intel(R) UHD Graphics (CML GT2)
media/shaders/bumpmapping/bumpmapping.fs.glsl: 0:6(9): error: unrecognized layout identifier `binding'

The example application does not render correctly.

---

Fix:
The bumpmapping.fs.glsl shader has #version 410 core. Changing this to #version 420 core will fix this issue, and the example appears correct.

binding was made core in 4.2 and so may not work as expected in 4.1. Some drivers may have not enforced this.

---

I would have opened a pull request to address this, but was not able to. Thanks.

Hardcoded glfw3 in cmake

On my operating system the name of a glfw library is libglfw.so.3, not libglfw3.so*.

It looks like the glfw3 string is hardcoded into CMakeLists.txt:

pkg_check_modules(GLFW REQUIRED glfw3)
set(COMMON_LIBS sb7 glfw3 X11 Xrandr Xinerama Xi Xxf86vm Xcursor GL rt dl)

When I replaced glfw3 by the ${GLFW_LIBRARIES} it started to work.

set(COMMON_LIBS sb7 ${GLFW_LIBRARIES} X11 Xrandr Xinerama Xi Xxf86vm Xcursor GL rt dl)

Could you add this change into repository?

few bugs in vmath.h

in function
template <typename T, int len>
static inline T angle(const vecN<T,len>& a, const vecN<T,len>& b)
{
return arccos(dot(a, b));
}
my g++ 5.4.0 tell me what he don't know what is a arccos.
also it seems to me that arkosinus should be taken from the scalar product divided by the product of the lengths of the vectors.
Did i miss something?

Installation in Windows 10 Visual Studio 2019

Windows / Microsoft Visual Studio 2019

I leave here the configuration of the installation of Visual Studio 2019 in Windows. Before modifying anything I got an error with the GLFW compiled libraries. The solution (or at least as it has worked for me) was changing the environment and assigning the platform on which the programs will run.
I have also fixed the output of the last cmake command where files were not being generated where they should be. This onstallation guide is the same as in the source code, only the essential parts are modified.

Install CMake. Windows binaries are available from http://www.cmake.org/.
Ensure that CMake is in your path.
Open a command prompt and change to the directory where you've checked out the code.

Build GLFW

If you are going to use the copy of GLFW included in the archive, enter the
GLFW directory in extern/glfw-3.0.4, and type:

cmake -G "Visual Studio 16 2019" -A Win32 .

Open the resulting GLFW.sln file in Visual Studio and build both the debug and release configurations.

Copy and rename the resulting glfw3 libraries:

• Copy glfw-3.0.4/src/Debug/glfw3.lib into the lib directory and rename it to glfw3_d.lib.
• Copy glf3-3.0.4/src/Release/glfw3.lib into the lib directory but don't rename it.

Build the samples

Open a command prompt and change to the build directory in the source archive.
Type:

cmake -G "Visual Studio 16 2019" -A Win32 -S .. -B .

Open the resulting superbible7.sln project in Visual Studio.

The examples will build into the bin directory.

I hope it works for you.
Good luck!

glMultiDrawElementsIndirect

apologies if i missed something, but i can not find an example of glMultiDrawElements or gl...Indirect

suggestion: book should reference program names in this repo

Overall the book is very helpful and I really appreciate the effort, but it would be a bit easier to cross-reference the source code described in the book if you highlighted the name of the program being discussed in the text. I'm looking at the book in Kindle reader by the way. For example, in the first OpenGL application discussed, the program name is "simpleclear" but it isn't mentioned in the book, I had to guess which one it was. Same for the next one.

I guess ?? in backtraces mean that driver has no debug symbols in it, don't know how to debug it further.

where can I find the ktxtool.exe and sb6mtool.exe?

No "CmakeList.txt" under build folder

When following this step of the build instructions:

Open a command prompt and change to the build directory in the source archive.
Type:
cmake -G "Visual Studio 12" .

The following error is thrown;

Make Error: The source directory "D:/Projects/sb7code/build" does not appear to contain CMakeLists.txt.

Despite there being a file named

!RUN CMAKE FROM HERE.txt

However running it from the root directory works.

creating your own project on visual studio

Thank you for all these great examples in the book. I am looking forward to go through them. I am new to opengl and I just purchased your book and was able to build on my Windows system and I go to run your examples. Then I wanted to add my own project in my VS2013 solution. I replicated all settings for running examples into my new small project. However, this is not trivial. Is there a go-by that you, the author, or anyone else can provide?
Thanks.

writing the first application

I followed the instructions and successfully built glfw and superbible7 in visual studio 2019.
I'm trying to follow through the book from the second chapter
But I'm not sure what to do next. There is no guide in between.
I have a good knowledge of C++ not so much on setups.
Can you tell me where I should start?

unistd.h

it cannot open unistd.h

Can´t get them to run on windows 10

The examples compile without any errors but when i try to run them nothing happens.
When i try to debug them from visual studio it freezes. When i try to open them from windows, explorer freezes.
I´m using Windows 10, Visual Studio 2013 and my graphics card is a nvidia gtx 680m

flare.ktx broken

Hi,
the mirrorclampedge example results in black screen. I tracked down the reason down to the flare.ktx being most likely broken.
The problem being:

---------------
GL_INVALID_ENUM in glTexStorage2D(internalformat = GL_RGB)
Message ID: 5
Source: API
Type: Error
Severity: high
---------------
GL_INVALID_OPERATION in glTexSubImage2D(invalid texture level 0)

Severity: high
---------------
GL_INVALID_OPERATION in glGenerateMipmap(zero size base image)
Message ID: 5

The KTX 1 file pHeader is invalid:

Do you have working version of flare.ktx?

Hi There,

Do the provided examples work with OpenGL 4.1 drivers?
I can build a project, but when I run .exe file nothing happens.

Thank you.

Missing perftest shaders

Hi,

I'm trying to work through your perf-readpixels project in the source code for the OpenGL Superbible. However, I notice that the shaders (and entire perftest folder) 'perftest/render.vs.glsl' & 'perftest/render.fs.glsl' are missing from the downloaded media. Can you make those two shaders available for download?

Thanks in advance (and for the book!)

Built using VS2013 against Windows 7 x64 bit using latest version of cmake (cmake-3.5.2-win32-x86)

Cannot compile in Ubuntu 17.10

the cmake command executes correctly, the make returns an error:

/usr/bin/ld: cannot find -lglfw3 /usr/bin/ld: cannot find -lXinerama /usr/bin/ld: cannot find -lXi /usr/bin/ld: cannot find -lXcursor collect2: error: ld returned 1 exit status CMakeFiles/wrapmodes.dir/build.make:95: recipe for target '../bin/wrapmodes' failed make[2]: *** [../bin/wrapmodes] Error 1 CMakeFiles/Makefile2:131: recipe for target 'CMakeFiles/wrapmodes.dir/all' failed make[1]: *** [CMakeFiles/wrapmodes.dir/all] Error 2 Makefile:83: recipe for target 'all' failed make: *** [all] Error 2

I tried both on Wayland and x11, none works, same issue, I do have glfw3 and glfw3-dev

Hints?

Will the media files get their own repository?

I would like to create a pull request for some shaders I tweaked, and also ask that media/textures/salad-gray.ktx is uploaded - it's not available in the .ZIP as of today (July 24th), and it is needed in line 90 of src/prefixsum2d/prefixsum2d.cpp.

Possible bug in prefixsum.cs.glsl file

Hi!

Could you check prefixsum.cs.glsl shader.
There could be a bug in the line 32. There is step < steps and I think it should be step <= steps, because in the first version it doesn't calculate the last step.

bumpmapping cannot work

i compile the solution under vs2015 with recompiled glew lib, sb7 lib. but the bumpmapping project cannot work, it seems the texture cannot display properly.

media file is unavailable

http://openglsuperbible.com/files/superbible7-media.zip does not seem to be available.

make error for Centos7 with current glfw install

Stack Overflow Description of Problem with Answer

GLFW v3 is installed, but not recognized when building samples.

Chapter info in samples

It would be very helpful to have the chapter number as a prefix to the sample folders.

An example of bumpmapping cannot appear.

Your GitHub repository is fine, but your media/shader has a trivial error:

media/shaders/bumpmapping/bumpmapping.fs.glsl:0(6) : error C7532: layout(binding) requires "#version 420" or later
0(6) : error C0000: ... or #extension GL_ARB_shading_language_420pack : enable
0(7) : error C7532: layout(binding) requires "#version 420" or later
0(7) : error C0000: ... or #extension GL_ARB_shading_language_420pack : enable

I fixed a version over 420 in your (fragment/vertex)shader code and it was working, yes that was trivial.

Convert files into UTF8

QtCreator complains about non utf8 character and forces me to chose an encoding. It is probably due to special character after "Copyright" word in files' headers.

Could you convert all files into UTF8 or remove special characters?
