FBO windows broken in recent revisions?

[m0bl0]

Hello,

windows with FBO drawable seem to be broken in recent revisions; this is the (first) error message that I get:
Got GL_INVALID_OPERATION before makeCurrent( ) in ..\lib\client\wglWindow.cpp:266

This worked fine in r3459, but is broken since r3467 (after the OSWindow<->GLWindow split).

Tested on WinXP and Win7, both x64.

To reproduce, start eqPly with the following config:
(removing the "device n" lines or using a comparable two-node config gives the same result)

#Equalizer 1.0 ascii

server
{
    config
    {
        appNode
        {
            pipe
            {
                device 0
                window
                {
                    viewport [ .25 .25 .5 .5 ]
                    channel { name "channel1" }
                }
            }
            pipe
            {
                device 1
                window
                {
                    attributes
                    {
                        hint_drawable FBO
                        planes_color  RGBA16F
                        planes_depth  ON
                    }
                    channel { name "channel2" }
                }
            }
        }
        compound
        {
            channel "channel1"
            wall
            {
                bottom_left  [ -.32 -.20 -.75 ]
                bottom_right [  .32 -.20 -.75 ]
                top_left     [ -.32  .20 -.75 ]
            }
           
            compound
            {
                viewport [ 0 0 1 .5 ]
            }
            compound
            {
                channel "channel2"
                viewport [ 0 .5 1 .5 ]
                outputframe {}
            }
            inputframe { name "frame.channel2" }
        }
    }    
}


Cheers,
Marc

We've fixed this (see related bug).


Best,

Almost, one remaining bug is that getFrameBufferObject is non-const in OSWindow, but the supposed override in GLWindow is const. (Though this only causes harmless(?) GL_INVALID_ENUMs on a glDrawBuffer call in channel.cpp). This can be fixed by adding the const back on OSWindow::getFrameBufferObject, like it was until r3459.
