Error 1
The code is just trying to access a repeated element:
this->State->GetExtension(LinkState::sync_interactive_renders,
this->GetSynchronizeInteractiveRenders());
But it seems that the compiler only sees the single element version
of GetExtension(). Perhaps we are not properly instantiating the
repeated one? The "no type named Repeated" seems like that may be
the case. This is with gcc 5.1.1.
To access a repeated extension, you should use GetRepeatedExtension().
Calling GetExtension() on a repeated extension is undefined behavior in
2.5.0. It's explicitly forbidden in 2.6.1.
Thanks for the response, but it looks like the Repeated reference was a
red herring, and it was a more fundamental mistake/typo. Looks like
this was meant to be a setter rather than a getter situation - which
actually looking at the code rather than just the error reveals. So I
think it should be:
void vtkSMCameraLink::UpdateState()
{
this->Superclass::UpdateState();
this->State->SetExtension(LinkState::sync_interactive_renders,
this->GetSynchronizeInteractiveRenders());
}
as sync_interactive_renders is bool type.
Thanks again for another pair of eyes.
