Android arm64-v8a - OpenCFile crashs
Hi
if I build Monkey2 for arm64-v8a all compiles fine (after EACCES fix from seyhajin - http://monkeycoder.co.nz/forums/topic/android-64bit-arm64-v8a/#post-16227).
After my App tries to read a config file it crashs at:
2019-07-22 07:43:55.587 18510-18679/com.lb.app I/MX2: Monkey 2 Runtime error: SIGNAL: Memory access violation 2019-07-22 07:43:55.587 18510-18679/com.lb.app I/MX2: {{!DEBUG!}} 2019-07-22 07:43:55.587 18510-18679/com.lb.app I/MX2: >OpenCFile:libc.FILE Ptr(path:monkey.types.String,mode:monkey.types.String);C:/dev/monkey2/modules/std/filesystem/filesystem.monkey2;926;5746 2019-07-22 07:43:55.587 18510-18679/com.lb.app I/MX2: path:String="en.txt" 2019-07-22 07:43:55.587 18510-18679/com.lb.app I/MX2: mode:String="rb"
Line 926 is: Local asset:=AAssetManager_open( asstMngr,path,0 ) Is differs in my source because I add some debug log output.
The same APK on a armeabi-v7a works fine (compiled for both v7a and v8a in one APK).
I'm using the latst NDK Version (20.0.5594570).
I re-compile it with you suggestion but it makes no difference. Anyway thanks for your input.
I think the reason for the issue is in a lower level because the 32 bit ARM version is runnig fine.

I may be wrong but maybe the hard coded value 10 in the Slice call in OpenCFile should be:
path=path.Slice( "${ASSETS}/".Length )

Apologies, I removed the suggestion after realizing I was confused. I became more confused when not seeing this in my windows config (macos only?):

I assume from your user name you are on Mac and have this switched on to enable the 64 bit mode?
No, I'm working with Win10.
