How to build OpenAL-Soft and set up it in Qt Creator for Android

@8Observer8
While you wait for a better answer, maybe from someone who knows about the code you are talking about. I don't know if it will help you diagnose, but I would say that the error and the screenshot indicate that when encountering

const float*RESTRICT coeffs

the symbol/token RESTRICT is not defined. Something (a #define?) in a header should have done so but appears not to have done. Maybe look where that is supposed to be defined to figure what has/hasn't happened?

8Observer8

Yes, I added #define RESTRICT and I see fewer errors. Some files have this line #include "config.h", but this file is not in the OpenAL-Soft source code. I added the empty config.h file. I think this file must be generated by CMake if you are compiling OpenAL-Soft from source. I found the config.h.in file that doesn't have the #define RESTRICT:

I tried to build OpenAL-Soft for Android but I have these errors: https://github.com/DJLink/android-openal-soft/issues/1

@8Observer8 You need to show the picture of Tools->Options->Devices->Android

8Observer8

@JoeCFD,

JoeCFD

@8Observer8 what is your targeted android version(s)?

8Observer8

@JoeCFD,

8Observer8

I added Bullet Physics to the project using sources. It works for emulator and for smartphone too:

JoeCFD

@8Observer8
from here:
https://developer.android.com/build/jdks

14 (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.

Still Android 7?

I have Redmi 4x with Android 7

JoeCFD

@8Observer8 That is very old. Then your JDK version is wrong at the first place.

8Observer8

@JoeCFD,

Android NDK: The armeabi ABI is no longer supported. Use armeabi-v7a.

I use armeabi-v7a when I build for smartphone (and x86_64 - for emulator) but how to use armeabi-v7a when I build from the console? It will be good to have at lease a library for smartphone.

JoeCFD

@8Observer8 show Projects->Build(Android)->Build Settings
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.

8Observer8

@JoeCFD,

For emulator:

For APK:

But I want to try to build the OpenAL-Soft shared (or static) library from the console using this command ndk-build. How to choose armeabi-v7a?

JoeCFD

@8Observer8 I guess you have a different version of qt creator. I do not know yours.

8Observer8

@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?

JoeCFD

@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.

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.

JoeCFD

@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.
