For each release we provide some pre-built binaries of the library [here](https://github.com/ARM-software/ComputeLibrary/releases)
These binaries have been built using the following toolchains:
- - Linux armv7a: gcc-linaro-4.9-2016.02-x86_64_arm-linux-gnueabihf
- - Linux arm64-v8a: gcc-linaro-4.9-2016.02-x86_64_aarch64-linux-gnu
- - Android armv7a: clang++ / libc++ NDK r17c
- - Android am64-v8a: clang++ / libc++ NDK r17c
+ - Linux armv7a: gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf
+ - Linux arm64-v8a: gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu
+ - Android armv7a: clang++ / libc++ NDK r18b
+ - Android am64-v8a: clang++ / libc++ NDK r18b
@warning Make sure to use a compatible toolchain to build your application or you will get some std::bad_alloc errors at runtime.

+ - gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu
To cross-compile the library in debug mode, with NEON only support, for Linux 32bit:
@subsection S3_3_android Building for Android
For Android, the library was successfully built and tested using Google's standalone toolchains:
- - clang++ from NDK r17c for armv7a
- - clang++ from NDK r17c for arm64-v8a
- - clang++ from NDK r18-beta1 for arm64-v8.2-a with FP16 support
+ - clang++ from NDK r18b for armv7a
+ - clang++ from NDK r18b for arm64-v8a
+ - clang++ from NDK r18b for arm64-v8.2-a with FP16 support
Here is a guide to <a href="https://developer.android.com/ndk/guides/standalone_toolchain.html">create your Android standalone toolchains from the NDK</a>
-- Download the NDK r17c from here: https://developer.android.com/ndk/downloads/index.html
+- Download the NDK r18b from here: https://developer.android.com/ndk/downloads/index.html
- Make sure you have Python 2.7 installed on your machine.
- Generate the 32 and/or 64 toolchains by running the following commands:
- $NDK/build/tools/make_standalone_toolchain.py --arch arm64 --install-dir $MY_TOOLCHAINS/aarch64-linux-android-ndk-r17c --stl libc++ --api 21
- $NDK/build/tools/make_standalone_toolchain.py --arch arm --install-dir $MY_TOOLCHAINS/arm-linux-android-ndk-r17c --stl libc++ --api 21
+ $NDK/build/tools/make_standalone_toolchain.py --arch arm64 --install-dir $MY_TOOLCHAINS/aarch64-linux-android-ndk-r18b --stl libc++ --api 21
+ $NDK/build/tools/make_standalone_toolchain.py --arch arm --install-dir $MY_TOOLCHAINS/arm-linux-android-ndk-r18b --stl libc++ --api 21
@attention We used to use gnustl but as of NDK r17 it is deprecated so we switched to libc++
@note Make sure to add the toolchains to your PATH:
- export PATH=$PATH:$MY_TOOLCHAINS/aarch64-linux-android-ndk-r17c/bin:$MY_TOOLCHAINS/arm-linux-android-ndk-r17c/bin
+ export PATH=$PATH:$MY_TOOLCHAINS/aarch64-linux-android-ndk-r18b/bin:$MY_TOOLCHAINS/arm-linux-android-ndk-r18b/bin
