IVRSystem missing from libopenvr_api_64.so -- VRInitError_Init_InterfaceNotFound #38

Open mncharity opened 7 years ago

mncharity commented 7 years ago

libopenvr_api_64.so currently does not contain the IVRSystem interface.

$ cd src/openvr/
$ grep IVRSystem libopenvr_api_*
Binary file libopenvr_api_32.dll matches
Binary file libopenvr_api_64.dll matches
$ strings libopenvr_api_64.so | grep _0
# ... a shorter list of interfaces than in .dll ...

Without IVRSystem, even VRApplication_Utility fails with VRInitError_Init_InterfaceNotFound.

$ cat x02.py
import sys
import time
import openvr

openvr.init(openvr.VRApplication_Utility)
openvr.shutdown()

$ python x02.py
