glLinkProgram throws an INVALID_VALUE without errors.

OpenGL OpenGL: Basic Coding

Hello everyone,
i’m trying to understand why my code throws an INVALID_VALUE when trying to link a successful attached set of shaders to a program.
I’ve checked the specifications and it seems that INVALID_VALUE is thrown only when the parameter specified is not a program created by OpenGL, but i’m quite sure it is.

The odd thing is that with NVIDIA drivers v.310 the problem disappears.
The code is the following:


glLinkProgram(m_programId);

	GLint linkStatus;
	glGetProgramiv(m_programId, GL_LINK_STATUS, &linkStatus);
	m_linked = (linkStatus == GL_TRUE);

	if(!m_linked)
	{
		GLint logLength;
		glGetProgramiv(m_programId, GL_INFO_LOG_LENGTH, &logLength);

		char* log = new char[logLength];
		GLsizei length;
		glGetProgramInfoLog(m_programId, logLength, &length, log);

		m_linkLog = log;

		delete[] log;
	}
	else
		m_linkLog = "";

	return m_linked;

But glGetProgramiv(m_programId, GL_LINK_STATUS, &linkStatus); returns GL_TRUE, and if i check the INFO_LOG anyways it’s always

Any suggestions?

Thanks

Seems like compiling an empty GEOMETRY_SHADER and linking it to the program raises an INVALID_VALUE but the LINK_STATUS and INFO_LOG are empty.
Should i report this to NVIDIA?
