内容简介:openssl NDK 交叉编译
移植openssl到android
创建工作目录,并进入
mkdir android cd android
下载源码
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
$ANDROID_NDK/build/tools/make-standalone-toolchain.sh --arch=arm --install-dir=./toolchain
导出环境变量(armeabi)
export ANDROID_HOME=`pwd` export TOOLCHAIN=$ANDROID_HOME/toolchain export 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

Did you know that any straight-line drawing on paper can be folded so that the complete drawing can be cut out with one straight scissors cut? That there is a planar linkage that can trace out any alg......一起来看看 《Geometric Folding Algorithms》 这本书的介绍吧!
