Building Android binary
|
|
=======================
|
|
|
|
In this article, we briefly describe how to build Android binary using
|
|
`Android NDK <http://developer.android.com/tools/sdk/ndk/index.html>`_
|
|
cross-compiler on Debian Linux.
|
|
|
|
The easiest way to build android binary is use Dockerfile.android.
|
|
See Dockerfile.android for more details. If you cannot use
|
|
Dockerfile.android for whatever reason, continue to read the rest of
|
|
this article.
|
|
|
|
We offer ``android-config`` and ``android-make`` scripts to make the
|
|
build easier. To make these script work, NDK toolchain must be
|
|
installed in the following way. First, let us introduce
|
|
``ANDROID_HOME`` environment variable. We need to install toolchain
|
|
under ``$ANDROID_HOME/toolchain``. An user can freely choose the path
|
|
for ``ANDROID_HOME``. For example, to install toolchain under
|
|
``$ANDROID_HOME/toolchain``, do this in the the directory where NDK is
|
|
unpacked:
|
|
|
|
.. code-block:: text
|
|
|
|
$ build/tools/make_standalone_toolchain.py \
|
|
--arch arm --api 16 --stl gnustl
|
|
--install-dir $ANDROID_HOME/toolchain
|
|
|
|
The API level (``--api``) is not important here because we don't use
|
|
Android specific C/C++ API.
|
|
|
|
The dependent libraries, such as OpenSSL and libev should be built
|
|
with the toolchain and installed under ``$ANDROID_HOME/usr/local``.
|
|
We recommend to build these libraries as static library to make the
|
|
deployment easier. libxml2 support is currently disabled.
|
|
|
|
Although zlib comes with Android NDK, it seems not to be a part of
|
|
public API, so we have to built it for our own. That also provides us
|
|
proper .pc file as a bonus.
|
|
|
|
If SPDY support is required for nghttpx and h2load, build and install
|
|
spdylay as well.
|
|
|
|
Before running ``android-config`` and ``android-make``,
|
|
``ANDROID_HOME`` environment variable must be set to point to the
|
|
correct path. Also add ``$ANDROID_HOME/toolchain/bin`` to ``PATH``:
|
|
|
|
.. code-block:: text
|
|
|
|
$ export PATH=$PATH:$ANDROID_HOME/toolchain/bin
|
|
|
|
To configure OpenSSL, use the following script:
|
|
|
|
.. code-block:: sh
|
|
|
|
#!/bin/sh
|
|
|
|
if [ -z "$ANDROID_HOME" ]; then
|
|
echo 'No $ANDROID_HOME specified.'
|
|
exit 1
|
|
fi
|
|
PREFIX=$ANDROID_HOME/usr/local
|
|
TOOLCHAIN=$ANDROID_HOME/toolchain
|
|
PATH=$TOOLCHAIN/bin:$PATH
|
|
|
|
export CROSS_COMPILE=$TOOLCHAIN/bin/arm-linux-androideabi-
|
|
./Configure --prefix=$PREFIX android
|
|
|
|
And run ``make install_sw`` to build and install without
|
|
documentation.
|
|
|
|
We cannot compile libev without modification. Apply `this patch
|
|
<https://gist.github.com/tatsuhiro-t/48c45f08950f587180ed>`_ before
|
|
configuring libev. This patch is for libev-4.19. After applying the
|
|
patch, to configure libev, use the following script:
|
|
|
|
.. code-block:: sh
|
|
|
|
#!/bin/sh
|
|
|
|
if [ -z "$ANDROID_HOME" ]; then
|
|
echo 'No $ANDROID_HOME specified.'
|
|
exit 1
|
|
fi
|
|
PREFIX=$ANDROID_HOME/usr/local
|
|
TOOLCHAIN=$ANDROID_HOME/toolchain
|
|
PATH=$TOOLCHAIN/bin:$PATH
|
|
|
|
./configure \
|
|
--host=arm-linux-androideabi \
|
|
--build=`dpkg-architecture -qDEB_BUILD_GNU_TYPE` \
|
|
--prefix=$PREFIX \
|
|
--disable-shared \
|
|
--enable-static \
|
|
CPPFLAGS=-I$PREFIX/include \
|
|
LDFLAGS=-L$PREFIX/lib
|
|
|
|
And run ``make install`` to build and install.
|
|
|
|
To configure zlib, use the following script:
|
|
|
|
.. code-block:: sh
|
|
|
|
#!/bin/sh -e
|
|
|
|
if [ -z "$ANDROID_HOME" ]; then
|
|
echo 'No $ANDROID_HOME specified.'
|
|
exit 1
|
|
fi
|
|
PREFIX=$ANDROID_HOME/usr/local
|
|
TOOLCHAIN=$ANDROID_HOME/toolchain
|
|
PATH=$TOOLCHAIN/bin:$PATH
|
|
|
|
HOST=arm-linux-androideabi
|
|
|
|
CC=$HOST-gcc \
|
|
AR=$HOST-ar \
|
|
LD=$HOST-ld \
|
|
RANLIB=$HOST-ranlib \
|
|
STRIP=$HOST-strip \
|
|
./configure \
|
|
--prefix=$PREFIX \
|
|
--libdir=$PREFIX/lib \
|
|
--includedir=$PREFIX/include \
|
|
--static
|
|
|
|
And run ``make install`` to build and install.
|
|
|
|
To configure spdylay, use the following script:
|
|
|
|
.. code-block:: sh
|
|
|
|
#!/bin/sh -e
|
|
|
|
if [ -z "$ANDROID_HOME" ]; then
|
|
echo 'No $ANDROID_HOME specified.'
|
|
exit 1
|
|
fi
|
|
PREFIX=$ANDROID_HOME/usr/local
|
|
TOOLCHAIN=$ANDROID_HOME/toolchain
|
|
PATH=$TOOLCHAIN/bin:$PATH
|
|
|
|
./configure \
|
|
--disable-shared \
|
|
--host=arm-linux-androideabi \
|
|
--build=`dpkg-architecture -qDEB_BUILD_GNU_TYPE` \
|
|
--prefix=$PREFIX \
|
|
--without-libxml2 \
|
|
--disable-src \
|
|
--disable-examples \
|
|
CPPFLAGS="-I$PREFIX/include" \
|
|
PKG_CONFIG_LIBDIR="$PREFIX/lib/pkgconfig" \
|
|
LDFLAGS="-L$PREFIX/lib"
|
|
|
|
And run ``make install`` to build and install.
|
|
|
|
After prerequisite libraries are prepared, run ``android-config`` and
|
|
then ``android-make`` to compile nghttp2 source files.
|
|
|
|
If all went well, application binaries, such as nghttpx, are created
|
|
under src directory. Strip debugging information from the binary
|
|
using the following command:
|
|
|
|
.. code-block:: text
|
|
|
|
$ arm-linux-androideabi-strip src/nghttpx
