二、NDK交叉编译openssl

# 1、创建开源模块根目录 #

mkdir AndroidWorkSpace/OpenSourceModule

# 2、openssl源码 #

获取openssl:https://www.openssl.org/source/

我做这个的时候最新的是1.1.1e  
openssl-1.1.1e.tar.gz

进入开源模块目录：  
cd OpenSourceModule  
解压到当前目录:  
tar vzxf openssl-1.1.1e.tar.gz

# 3、编译 #

进入openssl根目录：cd openssl-1.1.1e  
\-D\_\_ANDROID\_API\_\_目前理解是使用哪个版本api编译，也就是支持的最低api版本，因为android向下兼容。  
执行脚本build-android.sh

#!/bin/bash
    set -e
    set -x

    MY_OPENSSL_PATH=/home/renz/android/AndroidWorkSpace/OpenSourceModule
    func_cmp(){
    	make clean &&
    	rm -rf $MY_OPENSSL_PATH/OpensslDir/$ARCH &&
    	mkdir -p $MY_OPENSSL_PATH/OpensslDir/$ARCH &&
    	export PATH=$ANDROID_NDK/toolchains/llvm/prebuilt/linux-x86_64/bin:$PATH &&
    	./Configure $ARCH_NAME -D__ANDROID_API__=23 --prefix=$MY_OPENSSL_PATH/OpensslDir/$ARCH &&
    	make && make install
    }
    
    
    CC=clang
    ARCH_NAME=android-arm
    export PATH=$ANDROID_NDK/toolchains/llvm/prebuilt/linux-x86_64/bin:$PATH &&
    #先生成make一次，为了make clean能够执行
    ./Configure $ARCH_NAME -D__ANDROID_API__=23 --prefix=$MY_OPENSSL_PATH/OpensslDir/$ARCH
    
     #for ARCH in armeabi-v7a armeabi arm64-v8a x86 x86_64 mips mips64
    for ARCH in armeabi-v7a armeabi arm64-v8a x86 x86_64
    do
    	echo $ARCH
    	if [ "$ARCH" = "armeabi-v7a" ]; then
    		ARCH_NAME=android-arm
    	fi
    	if [ "$ARCH" = "armeabi" ]; then
    		ARCH_NAME=android-arm
    	fi
    	if [ "$ARCH" = "arm64-v8a" ]; then
    		ARCH_NAME=android-arm64
    	fi
    	if [ "$ARCH" = "mips" ]; then
    		ARCH_NAME=android-mips
    	fi
    	if [ "$ARCH" = "mips64" ]; then
    		ARCH_NAME=android-mips64
    	fi
    	if [ "$ARCH" = "x86" ]; then
    		ARCH_NAME=android-x86
    	fi
    	if [ "$ARCH" = "x86_64" ]; then
    		ARCH_NAME=android-x86_64
    	fi
    	echo $TOOL_CHAIN
    	func_cmp
    done

脚本需要根据自己的路径修改MY\_OPENSSL\_PATH变量  
脚本其中使用的是clang编译，如果想了解详细过程，请参考博客  
使用clang编译openssl1.1.1d  
https://blog.csdn.net/u011077027/article/details/102713175

编译完成会出现arm64-v8a  armeabi  armeabi-v7a  x86  x86\_64文件夹
