Building for Android

Assuming the Android Ndk is installed at location /path/to/toolchain, building libsndfile for Android (arm-linux-androideabi) should be as simple as:

./autogen.sh
export ANDROID_TOOLCHAIN_HOME=/path/to/android/toolchain
./Scripts/android-configure.sh
make

The Scripts/android-configure.sh contains four of variables; ANDROID_NDK_VER, ANDROID_GCC_VER, ANDROID_API_VER and ANDROID_TARGET that can be overridden by setting them before the script is run.

Since I (erikd), do almost zero Android development, I am happy accept patches for this documentation and script to improve its utility for real Android developers.

Using CMake

(Tested on Linux)

For convenience, export the following variables:

export ANDROID_ABI=arm64-v8a
export ANDROID_PLATFORM_API_LEVEL=29
export NDK_ROOT=/path/to/android/ndk

Set ANDROID_ABI, ANDROID_PLATFORM_API_LEVEL according to your target system. Now cd into the libsndfile root directory, and run

cmake -S . -B build  -DCMAKE_TOOLCHAIN_FILE=$NDK_ROOT/build/cmake/android.toolchain.cmake -DANDROID_ABI=$ANDROID_ABI -DANDROID_PLATFORM=$ANDROID_PLATFORM_API_LEVEL

cd into build and run make

cd build
make [-j <number of parallel jobs>]

This will build libsndfile for android.
