Pause Capture fails - compatibility log empty

Developer Tools Nsight Visual Studio Edition
1

I am using Nsight 4.0 beta with OpenGl program (and get the same error on nSight 3.2). When I try to pause I get the error

glTexParameterf (Zero texture object not supported – encountered on target of GL_TEXTURE_2D

When I run the compatibility log I get an empty file - ie no errors

An update - I would the log - you have to run the program not just exit at its start

log file

The follow code is causing at least one of the errors but I can see nothing wrong with the code

glGenFramebuffers(1, &c_ID);
glBindFramebuffer(GL_FRAMEBUFFER, c_ID);
// Create the multisample color render buffer image and attach it to the
// second FBO.
glGenTextures(1, &c_RenderTexture);
glBindTexture(GL_TEXTURE_2D_MULTISAMPLE, c_RenderTexture);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);
glTexImage2DMultisample(GL_TEXTURE_2D_MULTISAMPLE, c_Samples, GL_RGBA8, c_Width, c_Height,GL_FALSE);
glFramebufferTexture2D(GL_DRAW_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_TEXTURE_2D_MULTISAMPLE, c_RenderTexture, 0);
CHECKOPENGL_TRICKY;

Solution:

Do not use GL_TEXTURE_2D glTexParameteri/glTexParameterf with multisample textures

Hi,

That solution is not exactly correct. What the error is reporting is that you have 0 bound to the indicated texture binding point and that this is something that Nsight does not currently support (it is a compatibility feature that has been deprecated in Core OpenGL).

If you look at your statements, you are creating a texture, binding it to the GL_TEXTURE_2D_MULTISAMPLE binding point, but then attempting to set parameters on the GL_TEXTURE_2D binding point – note the mismatch. In this case nothing is bound to GL_TEXTURE_2D and this is why Nsight is reporting the error.
