INVALID_ENUM after glfwMakeContextCurrent

Hello.

glGetError() returns INVALID_ENUM immediately after creating a window and calling glfwMakeContextCurrent. What might cause this? I can’t reproduce it on my own computer. It’s only happening to some users of my GLFW application.

Here’s my code:

int glfwErr = glfwInit();
assert( glfwErr == GL_TRUE );

glfwWindowHint( GLFW_CONTEXT_VERSION_MAJOR, 3 );
glfwWindowHint( GLFW_CONTEXT_VERSION_MINOR, 2 );
glfwWindowHint( GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE );
glfwWindowHint( GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE );

glfwWindowHint( GLFW_SRGB_CAPABLE, GL_FALSE );
glfwWindowHint( GLFW_RESIZABLE, GL_FALSE );

m_wnd = glfwCreateWindow( w, h, name, nullptr, nullptr );
assert( m_wnd );

glfwMakeContextCurrent( m_wnd );
GLenum err = glGetError(); // INVALID_ENUM

You’re not using GLEW, then?

I am using GLEW and initializing it after the code I posted.

What is the output of glfwinfo?

I’ll attempt to get it when I can, but at the moment I’m not in contact with the person whose computer had the error.

I do at least know that glfwCreateWindow returned null for context version 3.3 with both GLFW_OPENGL_CORE_PROFILE and GLFW_OPENGL_ANY_PROFILE.

Well, a driver update fixed it, but another computer-savy user with a fancy gaming PC had the same problem, and I’m less optimistic that he also has old drivers.

Aside from the spurious error, does the application run correctly on their machines?

Yes, it seems to run correctly other than this error, at least for this one person.

Here’s the other person’s glfwinfo output. His drivers appear to be up to date:
