64bit make in Android fails

[Suhair Zain]

Hi,
I recently tried to make sfml for armeabi in android, following the tutorial at https://github.com/SFML/SFML/wiki/Tutorial%3A-Building-SFML-for-Android. It works without any issue and same goes for 32 bit architectures such as armeabi-v7a, x86, mips etc.

But once I try a 64bit platform such as arm64-v8a, mips64 or x86_64, an error is thrown. It's got something to do with missing JPEG LIBRARY. Could anyone take a look at it?

cmake -DANDROID_ABI=x86_64 -DCMAKE_TOOLCHAIN_FILE=../../cmake/toolchains/android.toolchain.cmake ../..

See also "/home/suhairzain/Downloads/SFML-2.3.2/build/x86_64/CMakeFiles/CMakeOutput.log".

This is the content of CMakeOutput.log

The target system is: Linux - 1 - x86_64
The host system is: Linux - 3.19.0-32-generic - x86_64

What could be the issue? The page lists 'other valid targets' as: armeabi-v7a, mips, and x86.

You can repeat the following steps for all available architectures. Unfortunately, you can't build all targets for SFML at once. The following lines create a armeabi build. If you'd like to build for any other target, just replace all occurences. Other valid targets would be armeabi-v7a, mips, and x86.

Is there some extra configuration to be done for 64bit architectures?

[EDIT]
Looking at https://github.com/SFML/SFML/tree/master/extlibs/libs-android, there are only 32bit architectures. How can I build it for the 64bit architectures?

No, you've done everything right. However, so far SFML only "ships" with the x86/armeabi/armeabi-v7a/mips dependencies as precompiled libraries. So you'll have to compile libjpeg and others on your own for this to work.

Edit:
Just saw your edit; you can find a build script under "tools", but you could just check the respective libraries (it's pretty much standard cross-compiling).

[Suhair Zain]

I don't have any experience in 'standard cross-compiling'. But I guess I could try it nonetheless. If I get it right, I can push a commit to make it part of SFML, right?

Please any update on this? Since August 2019 cannot be published any android application without included 64bit binaries...

I face similar problem :

EDIT : I made 64bit arm build without audio, just now I do not need it. For graphics I needed libfreetypefont.a which I found here :
https://github.com/fan-ADN/nendSDK-cocos2d-x/blob/master/CocosNendSample/cocos2d/external/freetype2/prebuilt/android/arm64-v8a/libfreetype.a

I created new folder arm64_v8a in ths folder and placed there libfreetype.a
https://github.com/SFML/SFML/tree/master/extlibs/libs-android/

Then I was able build arm8, now I will go to try it, hope it will not crash
