I just try to run this:
int main(int argc, char **argv) {
EGLDisplay display;
EGLConfig config;
EGLContext context;
EGLint num_config;
display = eglGetDisplay(EGL_DEFAULT_DISPLAY);
if (display == EGL_NO_DISPLAY)
{
std:: cout << "ERROR: EGL could not be initialized"<< std::endl;
exit(EXIT_FAILURE);
}
if (!eglInitialize(display, nullptr, nullptr))
{
std:: cout << "ERROR: Could not start EGL display connection"<< std::endl;
exit(EXIT_FAILURE);
}
if (eglChooseConfig(display, nullptr, &config, 1, &num_config) != EGL_TRUE)
{
std:: cout << "ERROR: Configuration selection failed" << std::endl;
exit(EXIT_FAILURE);
}
eglBindAPI(EGL_OPENGL_API);
context = eglCreateContext(display, config, EGL_NO_CONTEXT, NULL);
if (eglMakeCurrent(display, EGL_NO_SURFACE, EGL_NO_SURFACE, context) != EGL_TRUE) {
std:: cout << "ERROR: Display was not made current one"<< std::endl;
exit(EXIT_FAILURE);
}
GLenum err = glewInit();
if (GLEW_OK != err)
{
std:: cout << "GLEW Error: " << glewGetErrorString(err) << std::endl;
exit(EXIT_FAILURE);
}
// ... some code here
}
But when running it I have:
GLEW Error: Missing GL version
It looks like my glewInit()
fails with the GL context but I don't understand why, because my glewInit()
is called after context creation. And there is no error from EGL.
The purpose of this code is to be able to have an Opengl context without any window. This code was working in the past but not since I upgraded my Ubuntu 17.10 with Nvidia 384, working on Quadro K2000M.

UPDATE 13th February 2019:
I hit the 30,000 character limit in my other answer, and so had to post this as a separate answer.
I came across this nvidia blog post on Linking OpenGL for Server-Side Rendering.
This includes the following (emphasis mine):
When the classic OpenGL Application Binary Interface (ABI) was introduced 17 years ago, the only widely adopted windowing and display management system on linux was X11. OpenGL context management, which is not part of OpenGL itself, was therefore synonymous with the glX API. And because the only way to use OpenGL on Linux was via glX, functions for both OpenGL and glX were bundled into the same library, libGL.so.
Linking an OpenGL application was simple: you only needed to link against libGL.so.
Over the years, the situation has changed and a wide range of display managers have emerged. People want to have X11-based display managers on the same system with Wayland, or to use hardware-accelerated OpenGL on the same system with software-emulated OpenGL. This requires a cleaner separation between the OpenGL library and OpenGL context-management libraries.
GLVND, the OpenGL Vendor Neutral Dispatch for Linux, was born to meet this requirement.
To use glX and OpenGL today, you should link against libOpenGL.so as well as libGLX.so. The first contains the OpenGL symbols, the latter the GLX symbols. If you want to use EGL context management instead, link against libOpenGL.so and libEGL.so.
So, this suggests that to use EGL, I should be linking against libOpenGL.so instead of libGL.so.
To test this, I first installed drivers using the package manager:
$ sudo add-apt-repository ppa:graphics-drivers/ppa
$ sudo apt-get update
$ sudo apt-get install nvidia-410
$ sudo reboot
[after reboot]
$ dpkg -l | grep nvidia
ii nvidia-410 410.78-0ubuntu0~gpu16.04.1 amd64 NVIDIA binary driver - version 410.78

$ cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX x86_64 Kernel Module 410.78 Sat Nov 10 22:09:04 CST 2018
GCC version: gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.11)
As seen before, EGL fails with the packaged driver, when linking the test app against libGL.so:
$ wget https://gist.githubusercontent.com/funchal/bff0a8d6dae5b3ace1a88c392416b5bc/raw/1427821a2390a30779881ab59c55b5550a468919/main.c
$ gcc main.c -lGL -lEGL
$ ./a.out
egl 1.5
a.out: main.c:53: main: Assertion `renderer' failed.
Aborted (core dumped)
The machine contains both libGL.so and libOpenGL.so:
$ sudo find /usr -name libGL.so
/usr/lib32/nvidia-410/libGL.so
/usr/lib/nvidia-410/libGL.so
/usr/lib/x86_64-linux-gnu/mesa/libGL.so
/usr/lib/x86_64-linux-gnu/libGL.so
$ sudo find /usr -name libOpenGL.so

$ sudo find /usr -name libEGL.so

/usr/lib/nvidia-410/libEGL.so
/usr/lib/x86_64-linux-gnu/mesa-egl/libEGL.so
/usr/lib/x86_64-linux-gnu/libEGL.so
Linking the test app against libOpenGL.so works!
$ wget https://gist.githubusercontent.com/funchal/bff0a8d6dae5b3ace1a88c392416b5bc/raw/1427821a2390a30779881ab59c55b5550a468919/main.c

$ ./a.out
egl 1.5
renderer: Tesla K80/PCIe/SSE2
version: 4.6.0 NVIDIA 410.78
I then tested installing the drivers via a run file:
$ wget -L http://us.download.nvidia.com/XFree86/Linux-x86_64/410.93/NVIDIA-Linux-x86_64-410.93.run
$ sudo sh NVIDIA-Linux-x86_64-410.93.run
$ sudo reboot
[after reboot]
$ cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX x86_64 Kernel Module 410.93 Thu Dec 20 17:01:16 CST 2018
GCC version: gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.10)
These are the libraries available:
$ sudo find /usr -name libGL.so
/usr/lib32/libGL.so
/usr/lib/x86_64-linux-gnu/libGL.so
$ sudo find /usr -name libOpenGL.so
/usr/lib32/libOpenGL.so

$ sudo find /usr -name libEGL.so
/usr/lib32/libEGL.so
/usr/lib/x86_64-linux-gnu/libEGL.so
As seen in the previous update from 8th January, with drivers installed by a run file, EGL does work with libGL.so:
$ wget https://gist.githubusercontent.com/funchal/bff0a8d6dae5b3ace1a88c392416b5bc/raw/1427821a2390a30779881ab59c55b5550a468919/main.c
$ gcc main.c -lGL -lEGL
$ ./a.out
egl 1.5
renderer: Tesla K80/PCIe/SSE2
version: 4.6.0 NVIDIA 410.93
EGL also works when linking against libOpenGL.so:
$ wget https://gist.githubusercontent.com/funchal/bff0a8d6dae5b3ace1a88c392416b5bc/raw/1427821a2390a30779881ab59c55b5550a468919/main.c
$ gcc main.c -lOpenGL -lEGL
$ ./a.out
egl 1.5
renderer: Tesla K80/PCIe/SSE2
version: 4.6.0 NVIDIA 410.93
I'm not sure if this is related, but I noticed that the run file and packaged drivers have different dependencies linked into libGL.so. The run file installed drivers have the following dependencies, including libGLX.so:
$ ldd /usr/lib/x86_64-linux-gnu/libGL.so
linux-vdso.so.1 => (0x00007fff28ce5000)

libXdmcp.so.6 => /usr/lib/x86_64-linux-gnu/libXdmcp.so.6 (0x00007fda59ac0000)
While the package-installed drivers do not depend on libGLX.so, instead having libnvidia-tls.so and libnvidia-glcore.so as dependencies:
$ ldd /usr/lib/nvidia-410/libGL.so
linux-vdso.so.1 => (0x00007fff139dd000)

libXdmcp.so.6 => /usr/lib/x86_64-linux-gnu/libXdmcp.so.6 (0x00007fed5bfc5000)
To summarize the final fix to this problem:
Link against libOpenGL.so instead of libGL.so!
#define GLEW_EGL
on the gcc command-line so that glew.c
uses eglGetProcAddress()
instead of glXGetProcAddressARB()
:
g++ -DGLEW_EGL -DGLEW_STATIC -Iglew-2.1.0/include main.cpp glew-2.1.0/src/glew.c -lGL -lEGL
^^^^^^^^^^ this is where the magic happens
Building this code with the latest GLEW 2.1.0 tarball:

int main(int argc, char **argv)
{

if( display == EGL_NO_DISPLAY )
{

exit(EXIT_FAILURE);
}

exit(EXIT_FAILURE);
}

exit(EXIT_FAILURE);
}
if( num_config == 0 )
{
std:: cout << "ERROR: No configurations" << std::endl;
exit(EXIT_FAILURE);
}
eglBindAPI( EGL_OPENGL_API );
EGLContext context = eglCreateContext( display, config, EGL_NO_CONTEXT, NULL );
if( eglMakeCurrent(display, EGL_NO_SURFACE, EGL_NO_SURFACE, context) != EGL_TRUE )
{
std:: cout << "ERROR: Display was not made current one"<< std::endl;
exit(EXIT_FAILURE);
}
GLenum err = glewInit();
if (GLEW_OK != err)
{
std:: cout << "GLEW Error: " << glewGetErrorString(err) << std::endl;
exit(EXIT_FAILURE);
}
std::cout << glGetString( GL_VERSION ) << std::endl;
std::cout << glGetString( GL_VENDOR ) << std::endl;

return 0;
