How to build OpenAL-Soft and set up it in Qt Creator for Android
-
I tried to build OpenAL-Soft for Android but I have these errors: https://github.com/DJLink/android-openal-soft/issues/1
E:\Libs\open-soft-android\android-openal-soft-master\jni>ndk-build
fcntl(): Bad file descriptor
Android NDK: The armeabi ABI is no longer supported. Use armeabi-v7a.
Android NDK: NDK Application 'local' targets unknown ABI(s): armeabi

@8Observer8 You need to show the picture of Tools->Options->Devices->Android
-
@8Observer8 what is your targeted android version(s)?
-
I added Bullet Physics to the project using sources. It works for emulator and for smartphone too:

@8Observer8
from here:
https://developer.android.com/build/jdks14 (API 34) 17 Core libraries
13 (API 33) 11 Core libraries
12 (API 32) 11 Java API
11 and lower Android versions=============================
your JDK version should be 11, not 17 for Android 7.
Still Android 7? I guess most Android phones have version 12 or 13 now. -

I have Redmi 4x with Android 7

@8Observer8 That is very old. Then your JDK version is wrong at the first place.
Android NDK: The armeabi ABI is no longer supported. Use armeabi-v7a.
I use
armeabi-v7awhen I build for smartphone (and x86_64 - for emulator) but how to usearmeabi-v7awhen I build from the console? It will be good to have at lease a library for smartphone.

click qmake "Details" button under Build Steps. You will see options for ABIs on QtCreator 11.0.1(comes with Qt-5.15.2)
I use arm64-v8a and my JDK version is 11. My target Android versions are 12/13. -

But I want to try to build the OpenAL-Soft shared (or static) library from the console using this command
ndk-build. How to choosearmeabi-v7a? -
@8Observer8 I guess you have a different version of qt creator. I do not know yours.
-
@JoeCFD My version of Qt Creator is 7.0.0. But I use pure NDK from the console to build OpenAL-Soft from sources. How do you know that OpenAL-Soft doesn't support Android 7?
-
@8Observer8 You build OpenAL-Soft for Android 7. I did not say it does not support Android 7.
Instead you need JDK 11 to build C++ apps for Android 7. But in your settings, JDK 17 is used.@JoeCFD said in How to install OpenAL-Soft for Android in Qt Creator by copying OpenAL-Soft sources into a project:

I tried to run apps with Box2D and Bullet Physics on real smartphone Redmi 4x with Android 7. I use JDK 17 and it works. I tried to run an example with QMediaPlayer on my smartphone and it plays music. I think I found a solution. I should try to use Bass Audio Library for 3D sounds on Android. It's is too difficult to add OpenAL-Soft directly with sources. Now I know this information:
Note that OpenAL is LGPL-licensed. Which means you need to release the source to your application if you make it part of your application.

@8Observer8 Great it works for you with JDK 17. You can still build OpenAL-Soft to dynamic lib and add it to your app for Android. It does not violate LGPL-license.
@JoeCFD what do you think about this? https://github.com/AerialX/openal-soft-android How to build it?
-
Does anyone have compiled libraries (.so) of OpenAL-Soft for Android? I mean
armeabi-v7aandx86_64. I can't find step by step instructions. -

@8Observer8 you may need to change CMakefile or create a pro file for Android. And build it for Android. It is just another project.
@JoeCFD A lazy way to do it is that you find out all settings(flags and libs) for Android build in the Makefile(made from pro or cmakefile) of your Android project. Then, you open CMakefile of OpenAL-Soft with cmake-gui and add(or replace) all these settings to the corresponding locations. Do make and you will get the right lib for Android. I did it once for some testing and it worked.
Sure it is better to do it properly. It should not be that hard.
