I just sent this info to one of the Oculus programmers who wrote the SDK who responded with:
the issue there was a version of the
link.lib went out with the wrong
symbol name and would return that
error because it couldn’t find the
function in the main DLL. By the time
it fails and returns that error all
the important parts are initialized so
it’s non-fatal (assuming you’re not
using Ambisonics). Updating to a newer
version should resolve this, going
through perforce the fix went in on
1/26 so anything newer should be
solid.
I’ll see if I can get an updated version of our SDK into an upcoming release. It should be straightforward to DL a new Oculus sdk/DLL and use that with UE4.
