Google Play New problem : 64bits

[Ats]

So I simply tried to replace libzgeandroid.so by the new 64bits one but the apk just launch and close.
I think I have to say that the apk is for arm64 somewhere in this messy AndroidManifest.xml but I didn't find how to do that yet.

[VilleK]

Did you check if there is any information in the Android log?

I would expect it to just be to include libzgeandroid.so in the correct folder, which probably is something like "arm64-linux". But you could be right it needs some additional setting in the manifest too.

Hello. Sorry to reopen that coffin... I completely abandoned Google Play at the time and went to itch.io instead, then I forgot about the 64 bits version of ZGE for Android. But now I'm starting to receive complaints about players unable to run the Android version of Omeganaut on strict 64 bits phones, such as the Pixel 7. So I checked my good old tutorial to build ZGE for Android, and yes, it is 32 bits armeabi-v7a. So today I converted my compilation script from 32 bits:

Code: Select all

pushd "%~dp0"
if not exist "java\libs\armeabi-v7a\" mkdir java\libs\armeabi-v7a
if not exist "lib\arm-linux\" mkdir lib\arm-linux
PATH=C:\Android\android-ndk-r21e\toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86_64\bin;

popd

to 64 bits:

Code: Select all

pushd "%~dp0"
if not exist "java\libs\arm64-v8a\" mkdir java\libs\arm64-v8a
if not exist "lib\arm64-linux\" mkdir lib\arm64-linux

And everything is working nicely until it starts compiling ZExpressions.pas :

Code: Select all

ZExpressions.pas(2307,13) Error: Unknown identifier "R0"
ZExpressions.pas(2308,13) Error: Unknown identifier "R1"

ZExpressions.pas(2311,16) Error: Invalid reference syntax
ZExpressions.pas(2311,22) Fatal: Internal error 2014122002
Fatal: Compilation aborted

But those identifiers are in pure assembly, so I'm kind of stuck

Internet says that replacing R by X will do the trick. And also adjust the size of the registers. But I'm not sure about the $ifdef semantics. Should this work?

Code: Select all

// First parameters in registers, then on stack
if ArgCount > 4 then
begin
  {$IFDEF CPUARM} // 32-bit ARM
    P := @Args + 16; // Start after first 4 args (4 * 4 bytes = 16 bytes)
    Tmp := ArgCount - 4;
    asm
      ldr r0, Tmp
      ldr r1, P
      mov r3, #0
    .Lmyloop:
      ldr r2, [r1, r3]
      str r2, [r13, r3]
      add r3, r3, #4
      sub r0, r0, #1
      cmp r0, #0
      bgt .Lmyloop
    end;
  {$ENDIF}

  {$IFDEF CPUARM64} // 64-bit ARM
    P := @Args + 64; // Start after first 8 args (8 * 8 bytes = 64 bytes)
    Tmp := ArgCount - 8;
    asm
      ldr x0, Tmp
      ldr x1, P
      mov x3, #0
    .Lmyloop64:
      ldr x2, [x1, x3]
      str x2, [sp, x3]
      add x3, x3, #8
      sub x0, x0, #1
      cmp x0, #0
      bgt .Lmyloop64
    end;
  {$ENDIF}
end;

{$IFDEF CPUARM} // 32-bit ARM
  asm
    ldr r0, Args
    ldr r1, Args + 4
    ldr r2, Args + 8
    ldr r3, Args + 12

    ldr r4, TheFunc
    blx r4

    str r0, RetVal
  end;
{$ENDIF}

{$IFDEF CPUARM64} // 64-bit ARM
  asm
    ldr x0, Args
    ldr x1, Args + 8
    ldr x2, Args + 16
    ldr x3, Args + 24

    ldr x4, TheFunc
    blr x4

    str x0, RetVal
  end;
{$ENDIF}

I'll try that tomorrow, as it is super late.

Edit:
32 bits version is compiling and running fine, so the $ifdef statements should be ok. But I get another compilation problem with the 64 bits version:

Code: Select all

ZExpressions.pas(2953,32) Error: Overloaded functions have the same parameter list
ZExpressions.pas(2265,32) Error: Found declaration: Execute(PExecutionEnvironment);
ZExpressions.pas(2953,32) Error: Function header doesn't match any method of this class "Execute(PExecutionEnvironment);"
ZExpressions.pas(2265,32) Error: Found declaration: Execute(PExecutionEnvironment);

Edit 2:
I solved this by replacing line 2764

Code: Select all

{$endif}
{$if defined(cpuaarch64)}  // ARM64

by

Code: Select all

{$elseif defined(cpuaarch64)}  // ARM64 (not for Android)

So Android 64 doesn't enter the main 64 code. This needs to be reviewed, as there are a lot of $ifdef in this code...


Next compilation error:

Code: Select all

ZExpressions.pas(443,16) Error: Forward declaration not solved "destructor Destroy;"

coming from

Code: Select all

    {$if defined(cpux64) or defined(cpuaarch64)}
    destructor Destroy; override;
    {$endif}

And there, I don't understand exactly how Pascal works. I believe it's because the TExpExternalFuncCall.Destroy is now inaccessible for Android 64 due to previous modification:

Code: Select all

destructor TExpExternalFuncCall.Destroy;
begin
  fpmunmap(Trampoline,512);
end;

So let's add another $ifdef to handle 64 bits computers and android

Code: Select all

{$endif}

{$if defined(cpuaarch64)}  // ARM64

destructor TExpExternalFuncCall.Destroy;
begin
  fpmunmap(Trampoline,512);
end;

{$endif}

[Ats]

ZExpressions.pas is now compiling fine. But you should take a look at the $ifdef structure to verify that everything is fine, as there are a lot of imbricated tests...

Next errors are coming from ZPlatform_Android.inc:

Code: Select all

ZPlatform_Android.inc(522,38) Error: Call by var for arg no. 3 has to match exactly: Got "LongWord" expected "QWord"
ZPlatform_Android.inc(727,41) Error: Call by var for arg no. 3 has to match exactly: Got "LongWord" expected "QWord"

This should do:

Code: Select all

procedure Platform_InitAudio;
var
  {$IFDEF CPU64}
  id: QWord;
  {$ELSE}
  id: LongWord;
  {$ENDIF}
begin
  AudioTerminated := False;
  BeginThread(AudioCallback, nil, id);
end;

and

Code: Select all

function Platform_CreateThread(ZThread: TZThread): pointer;
var
  {$IFDEF CPU64}
  id: QWord;
  {$ELSE}
  id: LongWord;
  {$ENDIF}
begin
  BeginThread(ThreadWrapper, ZThread, id);
  Result := pointer(id);
end;

Next errors are directly linked to my previous change:

Code: Select all

ZPlatform_Android.inc(526,28) Error: Incompatible type for arg no. 1: Got "AudioCallback(Pointer):LongInt;", expected "<procedure variable type of function(Pointer):Int64;StdCall>"
ZPlatform_Android.inc(735,28) Error: Incompatible type for arg no. 1: Got "ThreadWrapper(Pointer):LongInt;", expected "<procedure variable type of function(Pointer):Int64;StdCall>"

Solved by adding some new $ifdef... By the way, there seems to be several ways to define the exact same thing in Pascal, and I don't know which semantic you prefer.

Code: Select all

{$IFDEF CPU64}
function AudioCallback(Data : pointer) : Int64;
{$ELSE}
function AudioCallback(P: Pointer): LongInt;
{$ENDIF}

and

Code: Select all

{$IFDEF CPU64}
function ThreadWrapper(Data : pointer) : Int64; stdcall;
{$ELSE}
function ThreadWrapper(Data : pointer) : longint;
{$ENDIF}

I don't know why this last one needs stdcall;, the compiler told me to add that.

And libs/arm64-v8a/libzgeandroid.so is now compiled!

Edit:
It's not working on my phone... I have both versions of libs in the project:
libs/armeabi/libzandroid.so
libs/arm64-v8a/libzandroid.so
The app doesn't crash, but it's just a black screen. Which means it tries to run the 64 version, which it is able to, otherwise it would fall back to the 32. But 64 version isn't rendering anything.

By the way, ZGE is looking for libs/armeabi/libzandroid.so in order to compile for Android, so I can't change the folder name to the official one "armeabi-v7a". It's not really a problem though.

Hi Ats,

Internet says that replacing R by X will do the trick.

Yep, the R registers are 32-bit while the X registers are 64-bit. However, i'd recommend using x8-x18 ( they are the 64-bit equivalent to r0-r10 ) instead of x0-x7 as these are generally used for function arguments ( by compilers ).

[Ats]

All right

Code: Select all

// First parameters in registers, then on stack
if ArgCount > 4 then
begin
  {$IFDEF CPUARM} // 32-bit ARM
    P := @Args + 16; // Start after first 4 args (4 * 4 bytes = 16 bytes)
    Tmp := ArgCount - 4;
    asm
      ldr r0, Tmp
      ldr r1, P
      mov r3, #0
    .Lmyloop:
      ldr r2, [r1, r3]
      str r2, [r13, r3]
      add r3, r3, #4
      sub r0, r0, #1
      cmp r0, #0
      bgt .Lmyloop
    end;
  {$ENDIF}

  {$IFDEF CPUARM64} // 64-bit ARM
    P := @Args + 64; // Start after first 8 args (8 * 8 bytes = 64 bytes)
    Tmp := ArgCount - 8;
    asm
      ldr x8, Tmp
      ldr x9, P
      mov x11, #0
    .Lmyloop64:
      ldr x10, [x9, x11]
      str x10, [sp, x11]
      add x11, x11, #8
      sub x8, x8, #1
      cmp x8, #0
      bgt .Lmyloop64
    end;
  {$ENDIF}
end;

{$IFDEF CPUARM} // 32-bit ARM
  asm
    ldr r0, Args
    ldr r1, Args + 4
    ldr r2, Args + 8
    ldr r3, Args + 12

    ldr r4, TheFunc
    blx r4

    str r0, RetVal
  end;
{$ENDIF}

{$IFDEF CPUARM64} // 64-bit ARM
  asm
    ldr x8, Args
    ldr x9, Args + 8
    ldr x10, Args + 16
    ldr x11, Args + 24

    ldr x12, TheFunc
    blr x12

    str x8, RetVal
  end;
{$ENDIF}

But unfortunately, it doesn't fix my issue. Here's the adb log:

So it seems to be running, but things aren't rendering. I'm pretty sure it's due to a #ifdef that runs a computer 64 function somewhere, but there are so much #ifdef that I don't even know where to look at.

Hi Ats,

So it seems to be running, but things aren't rendering.

Judging from the adb log it's ( at the very least ) unable to load any of the OpenGL functions .. hence the black screen.

Maybe something in ZPlatform_Android.inc isn't adjusted to 64-bit properly still? Since JNI_OnLoad is listed among the errors .. perhaps in LoadModule?

I was reading through the documentations about your previous edition of your post, the one talking about linking the 64 bits version of OpenGL for Android, So I tried this without results :
C:\FPC\trunk\bin\i386-win32\ppcrossa64 -B -MDelphi -Sghi -O3 -Tandroid -Paarch64 -XXis -vw -Filib\arm64-linux -FlC:\Android\android-ndk-r21e\platforms\android-29\arch-arm64\usr\lib -Fu. -Fu..\.. -FlC:\Android\android-ndk-r21e\sources\third_party\opengl\src\lib\arm64-v8a -FlC:\Android\android-ndk-r21e\platforms\android-29\arch-arm64\usr\lib -FUlib\arm64-linux\ -FEjava\libs\arm64-v8a\ -olibzgeandroid.so -dANDROID -dMINIMAL -Xd -CpARMV8 -FlGLESv2 -FuC:\FPC\trunk\units\aarch64-android\fcl-base -FuC:\FPC\trunk\units\aarch64-android\hash -FuC:\FPC\trunk\units\aarch64-android\rtl-objpas -FuC:\FPC\trunk\units\aarch64-android\paszlib zgeandroid.pas

Edit: now that I'm browsing the ndk sources, there's no sources\third_party\opengl\ folder... In fact, I found no trace of opengl in any android-ndk version: https://android.googlesource.com/platform/ndk/
So I don't think this is it.


Regarding my adb log, those are not Errors, but Executions. I have the same list if I run the working 32 bit version of my apk test. I think everything is going well but not showing anything

Hi Ats,

Oops .. i thought the E's in your log were equivalent to the red E's here:



Never mind then

Hahaha everything is so confusing when it comes to Android...
Speaking of which, all needed libs are located in android-ndk-r21e\platforms\android-29\arch-arm64\usr\lib folder, including the 64 bits version of libGLESv2.so , and everything in this directory is already linked in my original compilation script.
(I already tried adding this libGLESv2.so to my Android app com.txori.cube\libs\arm64-v8a folder, not working)

So I really think the problem comes from some $ifdef 64 in the source code. And there are a bunch of lookalikes in it:
{$ifdef CPU64}
{$if defined(cpux64)}
{$if defined(cpuaarch64)}
{$ifdef CPUARM64}

[Kjell]

Hi Ats,

Hahaha everything is so confusing when it comes to Android...

Yea .. plus i haven't done anything Android for years so i'm hopelessly out of the loop. Concerning the various definitions / constants you listed:

CPU64 = Any 64-bit CPU
cpux64 = x86-64 CPUs ( the 64-bit version of x86 )
cpuaarch64 = 64-bit ARM CPUs
CPUARM64* = 64-bit ARM CPUs

*Apparently some don't like the AArch64 ( ARM Architecture 64-bit ) name so they use ARM64 instead.

In ZOpenGL.pas, those lines are rather suspicious:

Code: Select all

{$ifdef android}
glOrtho : procedure (left, right, bottom, top, zNear, zFar: GLFLoat); {$IFDEF WIN32}stdcall;{$ELSE}cdecl;{$ENDIF}
glFrustum : procedure (left, right, bottom, top, zNear, zFar: GLFLoat); {$IFDEF WIN32}stdcall;{$ELSE}cdecl;{$ENDIF}
{$else}
glOrtho : procedure (left, right, bottom, top, zNear, zFar: GLdouble); {$IFDEF WIN32}stdcall;{$ELSE}cdecl;{$ENDIF}
glFrustum : procedure (left, right, bottom, top, zNear, zFar: GLdouble); {$IFDEF WIN32}stdcall;{$ELSE}cdecl;{$ENDIF}
{$endif}

Correct me if I'm wrong, but {$IFDEF WIN32} doesn't have anything to do inside a {$ifdef android}. I believe it should simply be:

Code: Select all

{$ifdef android}
glOrtho : procedure (left, right, bottom, top, zNear, zFar: GLFLoat); cdecl;
glFrustum : procedure (left, right, bottom, top, zNear, zFar: GLFLoat); cdecl;
{$else}
glOrtho : procedure (left, right, bottom, top, zNear, zFar: GLdouble); {$IFDEF WIN32}stdcall;{$ELSE}cdecl;{$ENDIF}
glFrustum : procedure (left, right, bottom, top, zNear, zFar: GLdouble); {$IFDEF WIN32}stdcall;{$ELSE}cdecl;{$ENDIF}
{$endif}

But that isn't solving my black screen problem...

I just remembered about logcat in order to check all the AndroidLog traces, so I had to test it before going to sleep...
So here are the logs for my simple cube apk 32 and 64 bits. I had to zip them as the forum doesn't support txt file upload.

The 64 version is throwing those errors:

Code: Select all

Hi,

I'm on vacation for another week so I can only make some guesses why it is not working.

For ZExpressions then I think 64-bit Android should use the cpuaarch64 ifdef section.

The "getTransport" errors is not something I recognize.

Please try with the absolute minimal ZGE project. I would start with a project that has App.ClearColor set to red and nothing else. When you have that working then we can take it step by step from there.
