Hello !
I’ve had all sort of problem trying to develop for the Oculus GO with unreal. I figured out it might be a version problem, and used github to download the last version recommended by oculus, the 4.22. I cloned the repository, opened the .sln in visual C++ 2017, I builded it, and then opened it with the debugger. Then I set the project settings following this tutoriel :
I can build the project, but as soon as I click on the launch buttons, unreal freezes and after a few second I get a message “fatal error” with no further explanation. And it crashes.
In the file MyProject/Saved/Logs, two things look like errors :
LogWindows: Failed to load ‘aqProf.dll’ (GetLastError=126)
LogWindows: File ‘aqProf.dll’ does not exist
LogWindows: Failed to load ‘VtuneApi.dll’ (GetLastError=126)
LogWindows: File ‘VtuneApi.dll’ does not exist
LogWindows: Failed to load ‘VtuneApi32e.dll’ (GetLastError=126)
LogWindows: File ‘VtuneApi32e.dll’ does not exist
LogConsoleResponse: Display: Failed to find resolution value strings in scalability ini. Falling back to default.
after some research it seems like this is actually not an error and is not the real problem. Here is what i think is the problem :
