Hello.
I'm using ubuntu 14.04.5 and the code cannot be compiled.
First i did cmake on build/ folder.

$ cmake ..

Then make fails:

$ make

Excited to receive the book. Disappointed to clone the examples and find that they simply did not build at all.

There are several errors in which memset or memcpy is not declared in scope. Can be fixed by including . I was also required to include <time.h> or <sys/time.h> here and there because some struct was declared but not defined.

There are several errors in which goto by passes the initialisation of local variables in a vglLoadDDS(). This might be legal C but is not C++, and the file is called vdds.cpp. I moved the declarations. But seriously? I haven't used goto in thirty years, if ever.

The particle simulator shader program made use of a STRINGIZE macro, which totally failed on the #version directive. All other examples appear to simply concatenate quoted strings.

My changes were just hacked in, so I won't submit a pull request.

I noticed that many of your examples go back and forth between setting up using glGen and glCreate is there a preferred method?

lib and include are configured,
gl3w and glfw are configured,
how to solve this problem?
WTF

03-drawingcommands shows two triangles, one is black and other is white.

How come the code is different from the book than it is here? It makes it very difficult to follow. Was there a reason for this?

"layout (triangle_strip, max_vertices = 240) out;\n"
240 exceeds my gpu limit
it's only 120 in the book, 120 works

void DoubleWriteExample::Initialize(const char * title) ... glBindImageTexture(0, output_texture, 0, GL_TRUE, 0, GL_READ_WRITE, GL_RGBA32F); ...
while 0 refers to the image unit (in fragment shader) which used as input and should be initialized by the render pipeline. what does this statement mean?

I just tried to clone the repository and the build/media folder doesn't get downloaded. I also tried the zip file and the same result.

To the best of my knowledge, there is no such correspondence description in the text/RedBook except the first program. The only hint is the two digits prefixing the directory and file names in the src folder. The remaining is guesswork. Although all my guess are correct so far, I still hope there is an official document that gives me such a correspondence between the source and textbook. For example, 01-keypress.cpp corresponds to what section(s) of the RedBook. Or, if such a doc exists but I missed it, please kindly let me know. I would appreciate this doc.

can anyone make this repo can build under osx

I'd appreciate it if you can provide the source code for the 8e, GLFW is good but I'm using freeGlut and don't want to change each source file manually...

There is not a file named gl.h in include/GL/, how to fix it?

There is no license information given for the source code in this repository which means that it is fully copyrighted and you must not even execute it. Does anyone know anything about the license status?

I set as startup project draw-xvfb and started one in Debug configuration. Seems there is a trouble reading mFrame. Is this a known issue?

Windows 11 Pro
Visual Studio 2022 Community Edition
Cmake 3.28.0 rc1

The 9th edition introduces the opengl 4.5 and prefers to use DSA methods (such as glCreate*).
But these demo codes are still not updated and do not match source codes on the 9th edtion redbook.

Hi dear author,
It's a great honor to write a letter here, I'm reading the book 9th nowadays, but the examples can not be built on ubuntu 18.04 with gcc. can you fix the error?

thank you
best regards
William

I run make, on Unix Makefile on Ubuntu,

I got this error:
lib/vdds.cpp:645:1: error: jump to label ‘done_close_file’ [-fpermissive]

How can I avoid it?, please help

Could anyone tell me how to build this project in ubuntu? Can I build in the traditional way as "mkdir build cd build cmake .. make"? I did this .But a lot of errors happen.I don"t know why.

There is a problem in vmath.h:1060.
template
static inline Tmat4 lookat(const vecN<T,3>& eye, const vecN<T,3>& center, const vecN<T,3>& up)
{
const Tvec3 f = normalize(center - eye);
const Tvec3 upN = normalize(up);
const Tvec3 s = cross(f, upN);
const Tvec3 u = cross(s, f);
const Tmat4 M = Tmat4(Tvec4(s[0], u[0], -f[0], T(0)),
Tvec4(s[1], u[1], -f[1], T(0)),
Tvec4(s[2], u[2], -f[2], T(0)),
Tvec4(T(0), T(0), T(0), T(1)));

return M * translate<T>(-eye);

}

I think we must guarantee that vector s and vector u are normalized, otherwise we cannot ensure matrix M is correct.(And in fact in some cases, M is incorrect).
So I changed them into:
const Tvec3 s = normalize(cross(f, upN));
const Tvec3 u = normalize(cross(s, f));

Hello Authors,
When running make all I'm getting an error compiling context.c which imports a joystick header that in tern imports regex.h which is declaring a namespace. Screenshot enclosed.

Thoughts?

03-pointsprites displays white squares instead of texture data of sprite2.tga.
I found that adding the following lines to the vermilion.cpp fixes the problem.

glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

Can someone look into this please?
Thank you.

(VM/WSL2 both happen) glfwWindowShouldClose: Assertion `window != NULL' failed.

The code can be compiled by vs 2015, but many project was crash when the start running those exe. Any suggest for this?

Hi,

Figure 9.1 show a Tessellation Quad based on the example given in Example 9.3.
The Example states
gl_TessLevelOuter[0] = 2.0;
gl_TessLevelOuter[1] = 3.0;
gl_TessLevelOuter[2] = 2.0;
gl_TessLevelOuter[3] = 5.0;

While the example states that gl_TessLevelOuter[3] is 5, based on the image it should be equal to 4.0.

In most case, the code is following the order "glVertexAttribPointer" first and then "glEnableVertexAttribArray". I think the interface "glVertexAttribPointer" is used to connect the buffer (managed by OpenGL) and the attrib (shader mananged by the pipeline), while the "glEnableVertexAttribArray" is used to submit the attachment to VAO then VAO can dispatch the buffer to related attribute, or vise vista.

But in Line 94 of "09-teapot.cpp"(and also the code for chapter 12 has the inverse order), the program is arranged in the inverse order
"void TeapotExample::Initialize(const char * title)
{
....
Line 94:
glEnableVertexAttribArray( vPosition );
glVertexAttribPointer( vPosition, 3, GL_FLOAT, GL_FALSE, 0,
BUFFER_OFFSET(0) );
"
well, is the latter usage correct, or what happen when glEnableVertexAttribArray is called?

Look uncomfortable, not all examples look uncomfortable.Vbm file where I can't find

when I compile this code in linux CENTOS7

I want to know what is the vbm file (the suffix is vbm) and how to open it?
