LIBZMQ ANDROID COMPILATION STEPS
|
|
================================
|
|
To launch the docker build:
|
|
|
|
$ docker build .
|
|
|
|
To launch the android build, you have to first install the android-ndk first in your HOME directory:
|
|
|
|
$ cd ~
|
|
$ export ANDROID_NDK_VERSION="r10e"
|
|
$ wget -q https://dl.google.com/android/ndk/android-ndk-${ANDROID_NDK_VERSION}-linux-x86_64.bin -O android-ndk-${ANDROID_NDK_VERSION}-linux-x86_64.bin
|
|
$ #check the hashes before executing this binary
|
|
$ md5sum android-ndk-r10e-linux-x86_64.bin
|
|
# 19af543b068bdb7f27787c2bc69aba7f android-ndk-r10e-linux-x86_64.bin
|
|
$ sha256sum android-ndk-r10e-linux-x86_64.bin
|
|
# 102d6723f67ff1384330d12c45854315d6452d6510286f4e5891e00a5a8f1d5a android-ndk-r10e-linux-x86_64.bin
|
|
$ chmod +x android-ndk-${ANDROID_NDK_VERSION}-linux-x86_64.bin
|
|
$ ./android-ndk-r10e-linux-x86_64.bin
|
|
$ export ANDROID_NDK_ROOT=${HOME}/android-ndk-r10e
|
|
$ export TOOLCHAIN_NAME=arm-linux-androideabi-4.9
|
|
$ export TOOLCHAIN_HOST=arm-linux-androideabi
|
|
$ export TOOLCHAIN_PATH=${ANDROID_NDK_ROOT}/toolchains/${TOOLCHAIN_NAME}/prebuilt/linux-x86_64/bin
|
|
$ export TOOLCHAIN_ARCH=arm
|
|
|
|
Then you can launch the build:
|
|
|
|
$ cd ~/libzmq/builds/android
|
|
$ ./build.sh
|
|
Cloning into 'libsodium'...
|
|
remote: Counting objects: 15246, done.
|
|
remote: Compressing objects: 100% (182/182), done.
|
|
Receiving objects: 16% (2440/15246)
|
|
[...]
|
|
|
|
A successful build should finish with the following message and give you back your shell prompt:
|
|
|
|
[...]
|
|
make[2]: Leaving directory '/tmp/android_build/arm-linux-androideabi-4.9/libzmq'
|
|
make[1]: Leaving directory '/tmp/android_build/arm-linux-androideabi-4.9/libzmq'
|
|
libzmq android build succeeded
|
|
$
|
|
|
|
You will then be able to see libzmq.so compiled in the prefix/ directory:
|
|
|
|
$ cd ~/libzmq/builds/android/prefix/arm-linux-androideabi-4.9/lib
|
|
$ ls
|
|
libsodium.a libsodium.la libsodium.so libzmq.a libzmq.la libzmq.so pkgconfig
|
|
|
|
You can then triple check that they are ARM libs:
|
|
|
|
$ cd ~/libzmq/builds/android/prefix/arm-linux-androideabi-4.9/lib
|
|
$ file libzmq.so
|
|
libzmq.so: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /system/bin/linker, not stripped
|
|
|
|
|
|
COMPILE WITH DOCKERFILE
|
|
=======================
|
|
|
|
To launch the docker build with a tagged image as a result:
|
|
|
|
$ cd ~/libzmq/builds/android
|
|
$ docker build -t libzmq-android:`date +"%y%m%d-%H%M%S"` .
|
|
$ docker build -t libzmq-android:latest .
|
|
|
|
If it is successful, it will end by "libzmq android build succeeded" followed by the ContainerID "e53db616aff4":
|
|
|
|
[...]
|
|
make[2]: Leaving directory `/tmp/android_build/arm-linux-androideabi-4.9/libzmq'
|
|
make[1]: Leaving directory `/tmp/android_build/arm-linux-androideabi-4.9/libzmq'
|
|
libzmq android build succeeded
|
|
---> e53db616aff4
|
|

|
|

|
|
|
|
$ docker images

|
|
|
If you want to collect the artifacts on the build, you can specify a directory in your HOME directory, such as "$HOME/libzmq-android-bins" for example:
|
|
|
|
$ mkdir -pv $HOME/libzmq-android-bins
|
|
$ docker run -v $HOME/libzmq-android-bins:/data libzmq-android:latest "cp -v /home/zmq/libzmq/builds/android/prefix/arm-linux-androideabi-4.9/lib/* /data"
