I tried adding both the -nop4 and installing the Perforce client but none worked. I followed the install guide and commented [RequireP4] in BuildPhysX.Automation.cs to ignore perforce - this worked but then the build failed when searching for MsDev14Exe and MsBuildExe in the same file. I commented out the two lines (820 and 821) which seem to have built PhysX correctly. I changed the PhysX.Build.cs according to your instructions and made the GetPhysXLibraryMode() function to always return PhysXLibraryMode.Debug. I opened the editor and the empty project I tried packaging before and repacked it for Linux distribution. Tried running it on the device and got the same error.
Is it possible that Unreal 4.19 or some other version will work on the Jetson TX2?
