Android (arm64-v8a)

pcspets

Hello

Arm64-v8a architecture is getting more and more popular on Android devices. I searched but couldn't even find a good tutorial to compile it myself. Is there anything out there to help me get going?

@SGaist
i am building up android arm64-v8a from source code,
but i have problem about configure setting,
i use the option -prefix {path} [http://radekp.github.io/qtmoko/api/buildsystem/over-configure-options-1.html]
and it did installed in {path} perfectly, but i want to use the arm64-v8a lib at different location or even difference computer,
the qt creator show error :
Cannot read {path}/mkspecs/android-g++/qmake.conf: No such file or directory
when i put arm64-v8a to other position: ~/Qt/qt5/arm64-v8a and add qmake in qt creator
but it always got errors, and point to prefix {path}

Is there any solution about this?
or should i remove -prefix option

btw, i am using mac

Hi,

Do you mean you are moving your Qt installation around on your computer ?

@SGaist
yes, you are right.
but i got it, there is a file named qt.conf in android_armv7a/bin
i used it in android_arm64-v8a/bin/qt.conf as well, and it worked.

in qt.conf, i placed this then i could move it to anywhere

[Path]
Prefix: ..

and below was how i built the library

git clone git://code.qt.io/qt/qt5.git qt5
cd qt5
perl init-repository

./configure \

-xplatform android-g++ \

@love8879201 Hello, with what can I say that I can have a simile and compile my codes on my cell phone? Because it has arm64-v8a and it does not let me

@love8879201 Why do you use darwin library to compile qt for android?
