I’m trying to ‘detach’ a program stage using
glUseProgramStages( name, stage, 0 )
but the debug log is returning an error reporting
error : 1008 : glUseProgramStages parameter <program> has an invalid value ‘0’: must be a valid program object name (GL_INVALID_VALUE)
the standard says
If UseProgramStages is called with <program> set to zero or with a program object that contains no executable code for a given stages, it is as if the pipeline object has no programmable stage configured for the indicated shader stages.
Which seems to say to me the driver is wrong? Or have I misunderstood the standard?
