Embarcadero RAD Delphi 10.3.3, cannot compile my app with Box2D library for 64-bits Android

Cannot compile my App for Android 64-bit with Delphi 10.3.3.
My App is using Box2D library.
While compile I get following errors:
[DCC Error] E2597 C:\Users\Public\Documents\Embarcadero\Studio\android-ndk-r17b\toolchains\aarch64-linux-android-4.9\prebuilt\windows\aarch64-linux-android\bin\ld.exe: cannot find -lFlatBox2D
C:\Users\Public\Documents\Embarcadero\Studio\android-ndk-r17b\toolchains\aarch64-linux-android-4.9\prebuilt\windows\aarch64-linux-android\bin\ld.exe: cannot find -lgnustl_static
Compilation for Android 32-bit of same App is successful.
Compilation of another my (simple) App for Android 64-bits works fine.
So, I realized, that problem is only with Box2D for Android 64-bits used in my App.
Then I also tested compilation of Box2D TestBed App that is coming with RAD (here ...\Embarcadero\Studio\20.0\Samples\Object Pascal\Multi-Device Samples\Physics\TestBed\) - the same issue - it is compiled successfully for Android 32-bits, but same error when I'm compiling TestBed for Android 64-bits!
Please help. Thousands of lines of code in my App already, and now it is full stop - can't build it for Android 64-bits [scared]
UPDATE1
Second error "cannot find -lgnustl_static" fixed by adding path C:\Users\Public\Documents\Embarcadero\Studio\android-ndk-r17b\sources\cxx-stl\gnu-libstdc++\4.9\libs\arm64-v8a into menu Tools->Options, then 'SDK Manager'->NDK->'Android SDK 25.2.5 64-bits'-> value for 'Delphi NDK Library path'.
However, the first problem 'cannot find -lFlatBox2D'still exists.
I found only 2 files of library libFlatBox2D.a on my computer, it is
C:\Program Files (x86)\Embarcadero\Studio\20.0\lib\android\debug
C:\Program Files (x86)\Embarcadero\Studio\20.0\lib\android\release
Both paths I added to the same 'Delphi NDK Library path' at SDK Manager for Android 64bit.
However, now getting error message skipping incompatible libFlatBox2D.a when searching for -lFlatBox2D for each of these paths.
So the question now - where to find a compatible libFlatBox2D.a that required for Android 64bits?
UPDATE2:
Hm... and in following 2 android64 paths do not have any libFlatBox2D.a files.
C:\Program Files (x86)\Embarcadero\Studio\20.0\lib\android64\debug
C:\Program Files (x86)\Embarcadero\Studio\20.0\lib\android64\release
Does it mean, that 10.3.3 Delphi installation is missing 64-bits Box2D android library?
UPDATE3:
As answered by #Stefanos , now I have 64bit version of libFlatBox2D.a.
But now while compiling I receiving count of 1700 linker errors about Box2D names , all of them similar to below:
[DCC Error] E2597 C:\Users\Public\Documents\Embarcadero\Studio\20.0\Samples\Object Pascal\Multi-Device Samples\Physics\TestBed\Android64\Debug\Box2D.Common.o: In function `Box2d::Common::Create_b2Draw_delegate(System::DelphiInterface<Box2d::Common::Ib2Draw>)':

etc...etc...
UPDATE4: Current status
I'm looking now for original libFlatBox2D.a library file for Android 64-bits (Delphi 10.3.3). If anyone has it, please share it with me.
The above attempts were not successful. An 'original' 64bits libFlatBox2D.a is required, which is not in my installation of RAD 10.3.3...
UPDATE5:
Embarcadero QA created a ticket:
https://quality.embarcadero.com/browse/RSP-27762
Will wait from their solution.

You have to create a new Package with name FlatBox2D, add all FlatBox units from ..\studio\20.0\source\FlatBox2D and compile it for Android64.
I have created the package and compiled both debug and release versions for Android64 with Delphi 10.3.3. In the link below you will find the new package files and the Android64 folder where you can find the libFlatBox2D.a for Debug and Release. Just copy the .a file to the corresponding folder in ..\studio\20.0\lib\Android64.
You can always compile the package on your own by just copying the FlatBox2D.dpr and FlatBox2D.dproj files in ..\studio\20.0\source\FlatBox2D, load the dpr in Delphi and compile it for Android64...

How to use phonegap-facebook-plugin in ionic?

I'm building an app in ionic/Cordova in which I want my users to be able to log in using Facebook. So I'm trying to install the PhonegapFacebookPlugin that I found on ngCordova.com.
The first thing that I noticed was that the docs on the ngCordova.com website for installing the plugin on Android are different from the docs on the project's github docs. So I first tried using the (simpler) instructions on the github page first, which after installing and trying to use the following code:
facebookConnectPlugin.login(['email'],
function(data){ console.log(JSON.stringify(data));},
function(error){console.log(error);});
led to these errors:
file:///android_asset/www/lib/phonegap-facebook-plugin-master/facebookConnectPlugin.js: Line 181 : Uncaught ReferenceError: require is not defined
file:///android_asset/www/js/app.js: Line 23 : Uncaught TypeError: Cannot read property 'Keyboard' of undefined

at HTMLDocument.tapTouchEnd (file:///android_asset/www/lib/ionic/js/ionic.bundle.js:2918:5)
After running into these errors, I tried continuing with the more extensive installation instructions on the ngCordova website, but the following command:
android update project --subprojects --path "platforms/android" --target android-19 --library "com.phonegap.plugins.facebookconnect/FacebookLib"
led to the following error:
Resolved location of library project to: /Users/kramer65/repos/my-app/platforms/android/com.phonegap.plugins.facebookconnect/FacebookLib
Error: Project folder '/Users/kramer65/repos/my-app/platforms/android/com.phonegap.plugins.facebookconnect/FacebookLib' is not a valid directory.
Error: No Android Manifest at: /Users/kramer65/repos/my-app/platforms/android/com.phonegap.plugins.facebookconnect/FacebookLib
This makes sense, because there is no folder called com.phonegap.plugins.facebookconnect/ in the platforms/android/ folder. I don't really know why not though. Do I need to copy-paste it there? Or did something go wrong in a previous step?
I'm stuck here and I really need to get this working. Any help would be greatly appreciated!

Can't build streamer tutorial for android on mac

Can't build streamer tutorial_3 for android on mac
I,ve got all environment variables needed.
My eclipse can't to resolve some symbols, but to some of them i can get by pushing F3. It's very strange for me.
Here is the command line output:

23:04:10 Build Finished (took 3s.740ms)*
I use ndk-10r and gst-1.4.0.
I know that there is no interfaces/xoverlay in new streamer.
EDIT
I've built ok, but steel got underlines of many glib-types and GST-macross. Here is a screenshot:
what is interesting that i have no underlined headers, for example: i've include pthread.h but have got underlined pthread_t and phtread_key_t....
i think that i have not install some general libraries on my mac, something like libc or what ever...may it couse this problem? The problem is that i can't run my app from eclipse. and for more: i use DS-5 CE IDE

This is most likely because we build the android 1.4.x cerbero packages with the r9d NDK.
You might want to use the r9d NDK until we provide binaries built with a more recent NDK (started some builds to see if everything goes through fine).

andEngine Android-Studio linker Error during Build

I took the source of AndEngine from their git repo, downloaded a fresh AndroidStudio, sdk and ndk,imported it, and tried to creat a simple new empty GameActivity extends BaseGameActivity.
But I could not start it, cause I get the following errors:

Does anyone know how to fix this? Or if I'm just using the wrong tools, what can you recommend?

I managed to get my project to compile. The problem seems to me that AS and ndk dont work together well yet. Any case check my blog on setting up the project:-
AS and AndEngine setup

It seems to be easier using the official intellij version instead of android studio. And as both are very similar in use, it't doesn't really matter. Together with some ndk-build hints from the answer of lakshman5876, it finally worked very well. Thanks

Compiling for Android using Make on OSX

Fair warning I am somewhat new to GCC development.
I am currently trying to do a personal port of Box2D to android (tech arm). I create a standalone toolchain, export the following....
export PATH=/tmp/my-android-toolchain/bin:$PATH
export CC=arm-linux-androideabi-gcc
export CXX=arm-linux-androideabi-g++
Then I run Make, everything "seems" to be running fine, however, at the end I see...
/private/tmp/my-toolchain/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld: error: bin/Debug/libBox2D.a: no archive symbol table (run ranlib)
/private/tmp/my-toolchain/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld: obj/Debug/HelloWorld/Helloworld.o: in function main:../../HelloWorld/Helloworld.cpp:38: error: undefined reference to 'b2World::b2World(b2Vec2 const&)'
/private/tmp/my-toolchain/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld: obj/Debug/HelloWorld/Helloworld.o: in function main:../../HelloWorld/Helloworld.cpp:47: error: undefined reference to 'b2World::CreateBody(b2BodyDef const*)'
/private/tmp/my-toolchain/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld: obj/Debug/HelloWorld/Helloworld.o: in function main:../../HelloWorld/Helloworld.cpp:53: error: undefined reference to 'b2PolygonShape::SetAsBox(float, float)'
If I open up a new terminal (essentially killing the exports) and delete the bin and obj folder everything compiles fine. A quick Google search suggests this could be related to it using the llvm compiler instead of GCC (although with my CC I think this less likely). There are the following instructions for llvm in the standalone toolchain doc...
If you wish, add --llvm-version=3.1 to also copy clang/llvm 3.1.
Should I add llvm? Is this an issue with bionic being different?
Thanks!

You are likely using the OSX version of ar. Can't tell for sure from you log. Try setting export AR=arm-linux-androideabi-ar
