openssl NDK 交叉编译

移植openssl到android

创建工作目录，并进入

1 2	mkdir android cd android

下载源码

1 2	wget https: //www.openssl.org/source/openssl-1.1.0e.tar.gz tar xfz openssl- 1.1. 0e .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）

编译并安装

cd openssl- 1.1. 0e/ ./Configure android \ --prefix=$TOOLCHAIN/sysroot/usr/local \ -- with-zlib-include=$TOOLCHAIN/sysroot/usr/include \ -- with-zlib-lib=$TOOLCHAIN/sysroot/usr/lib \ zlib \ no-asm \ no-shared \ no-unit-test make -j4 make install

卸载

1	make uninstall
