libnghttp2 NDK 交叉编译

移植nghttp2到android

创建工作目录，并进入

1 2	mkdir android cd android

clone源码

1	git clone git@github.com:nghttp2/nghttp2.git

生成交叉编译工具链

1	$ANDROID_NDK/build/tools/make-standalone-toolchain.sh --arch=arm --install-dir=./toolchain

导出环境变量

export CURRENT_HOME=`pwd`
export TOOLCHAIN=$CURRENT_HOME/toolchain
export PATH=$TOOLCHAIN/bin:$PATH
export PKG_CONFIG_LIBDIR=$TOOLCHAIN/lib/pkgconfig
export CPPFLAGS="-fPIE -I$TOOLCHAIN/sysroot/usr/include"
export LDFLAGS="-fPIE -pie -I$TOOLCHAIN/sysroot/usr/lib"

编译并安装

cd nghttp2
autoreconf -i
./configure --enable-lib-only \
    --host=arm-linux-androideabi \
    --build=`dpkg-architecture -qDEB_BUILD_GNU_TYPE` \
    --disable-shared \
    --prefix="$TOOLCHAIN/sysroot/usr/local"
make
make install

卸载

1	make uninstall
