Error in NV's implement for glClearNamedFramebufferfi

I run across a bug when using OpenGL 4.5 DSA functions, on nvidia's GTX760M These are three pieces of code: 1. the old fashion

glClear(GL_DEPTH_BUFFER_BIT);

2. the modern fashion

glBindFramebuffer(GL_DRAW_BUFFER, 0);
glClearBufferfi(GL_DEPTH_STENCIL, 0, 1.f, 0);

3.the dsa fashion

glClearNamedFramebufferfi(0, GL_DEPTH_STENCIL, 1.f, 0);

But only the first and the second code work. So is this a bug or my mistake?

Solution

  • It's actually a bug of glew, just change the prototype of glClearNamedFramebufferfi to

    typedef void (GLAPIENTRY * PFNGLCLEARNAMEDFRAMEBUFFERFIPROC) (GLuint framebuffer, GLenum buffer, GLuint drawbuffer, GLfloat depth, GLint stencil);
