[osg-users] Possible bug in dev version:no call to initializeExtensionProcs for embedded window

[Sergey Kurdakov]

Hi Robert,

 I tracked my error.

my osg is a port of osg to emscripten, so no switch of contexts happens,
for that matter to reduce workload I commented in

void ViewerBase::renderingTraversals()

line
makeCurrent(*itr);

in

for(itr = contexts.begin();
        itr != contexts.end() && !_done;
        ++itr)
    {
        if (!((*itr)->getGraphicsThread()) && (*itr)->valid())
        {
            doneMakeCurrentInThisThread = true;
            makeCurrent(*itr);
            (*itr)->runOperations();
        }
    }

that was fine for older version of osg, never version initializes
extensions in a first call to makeCurrent(*itr);

 now I uncommented this line in my code but keep porting other things in
new version of osg though.

so there is nothing wrong with osg at all - that was just an artifact of my
port and different behavior to init extensions, sorry for wrong call.

Regards
Sergey
