CURL NDK 交叉编译

移植curl到android，且支持https和http2.0

依赖前两篇文章

创建工作目录，并进入

1 2	mkdir android cd android

下载源码

1 2	wget https://curl.haxx.se/download/curl-7.53.1.tar.gz tar xfz url-7.53.1.tar.gz

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(armeabi)

export ANDROID_HOME=`pwd`
export TOOLCHAIN=$ANDROID_HOME/toolchain
export PKG_CONFIG_LIBDIR=$TOOLCHAIN/lib/pkgconfig
export CROSS_SYSROOT=$TOOLCHAIN/sysroot
export PATH=$TOOLCHAIN/bin:$PATH
export TOOL=arm-linux-androideabi
export CC=$TOOLCHAIN/bin/${TOOL}-gcc
export CXX=$TOOLCHAIN/bin/${TOOL}-g++
export LINK=${CXX}
export LD=$TOOLCHAIN/bin/${TOOL}-ld
export AR=$TOOLCHAIN/bin/${TOOL}-ar
export RANLIB=$TOOLCHAIN/bin/${TOOL}-ranlib
export STRIP=$TOOLCHAIN/bin/${TOOL}-strip
export ARCH_FLAGS="-mthumb"
export ARCH_LINK=
export CFLAGS="${ARCH_FLAGS} -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64"
export CXXFLAGS="${CFLAGS} -frtti -fexceptions"
export LDFLAGS="${ARCH_LINK}"

编译并安装

cd curl-7.53.1
autoreconf -i
./configure --prefix=$TOOLCHAIN/sysroot/usr/local \
       --with-sysroot=$TOOLCHAIN/sysroot \
       --host=arm-linux-androideabi \
       --with-ssl=$TOOLCHAIN/sysroot/usr/local \
       --with-nghttp2=$TOOLCHAIN/sysroot/usr/local \
       --enable-ipv6 \
       --enable-static \
       --enable-threaded-resolver \
       --disable-dict \
       --disable-gopher \
       --disable-ldap --disable-ldaps \
       --disable-manual \
       --disable-pop3 --disable-smtp --disable-imap \
       --disable-rtsp \
       --disable-shared \
       --disable-smb \
       --disable-telnet \
       --disable-verbose
make -j4
make install

卸载

1	make uninstall

configure完成后检查输出结果是否enable ssl, enable https, enable http2.0
