由于项目更新，需要将OpenSSL库进行升级，之前由于使用的OpenSSL库为1.1.1m，后来不知道听哪里说1.1.1系列后面不再维护。好嘛，那就更新一下。

直接使用官方库进行编译

下面说下自己的步骤：

下载最新的OpenSSL-官网，github. 解压下载好的源码创建存放编译好好静态库的文件夹: mkdir openssl_64 配置文件夹打开终端cd 到 OpenSSL源码的路径下，然后： ./Configure iphone-cross --profix=xx/openssl-3.1.0-a/openssl_arm64 1 export CC="clang" 2 export CROSS_TOP="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer" 3 export CROSS_SDK="iPhoneOS.sdk" 执行OpenSSL 提供的编译 ./Configure ios64-cross make （似乎可有可无）在OpenSSL源码目录下，可以看到新生成的libcrypto.a libssl.a就是需要的静态库，include目录下就是头文件使用Github 上脚本编译

如果这个出问题了可以，可以在github上找一些脚本进行编译，但是大家注意自己看脚本，大多脚本会有一些版本限制。这个时候需要根据编译错误进行修改。以下面github上的脚本为例： openssl_for_ios_and_android

这里主要记录Openssl的脚本：

脚本分两份，一份是公用文件:build-ios-common.sh

source ./build-common.sh if [ -z ${api+x} ]; then api="8.0" fi if [ -z ${arch+x} ]; then arch=("armv7" "arm64" "arm64e" "x86_64") fi if [ -z ${sdk+x} ]; then sdk=("iphoneos" "iphoneos" "iphoneos" "iphonesimulator") fi if [ -z ${platform+x} ]; then platform=("iPhoneOS" "iPhoneOS" "iphoneos" "iPhoneSimulator") fi export PLATFORM_TYPE="iOS" export IOS_MIN_TARGET="$api" export ARCHS=(${arch[@]}) export SDKS=(${sdk[@]}) export PLATFORMS=(${platform[@]}) # for test !!! # export ARCHS=("armv7") # export SDKS=("iphoneos") # export PLATFORMS=("iPhoneOS") function get_ios_arch() { local common_arch=$1 case ${common_arch} in armv7) echo "armv7" ;; arm64) echo "arm64" ;; arm64e) echo "arm64e" ;; x86) echo "x86" ;; x86_64) echo "x86-64" ;; esac } function ios_get_build_host() { local arch=$(get_ios_arch $1) case ${arch} in armv7) echo "armv7-ios-darwin" ;; arm64) echo "aarch64-ios-darwin" ;; arm64e) echo "aarch64-ios-darwin" ;; x86) echo "x86-ios-darwin" ;; x86-64) echo "x86_64-ios-darwin" ;; esac } function set_ios_cpu_feature() { local name=$1 local arch=$(get_ios_arch $2) local ios_min_target=$3 local sysroot=$4 case ${arch} in armv7) export CC="xcrun -sdk iphoneos clang -arch armv7" export CXX="xcrun -sdk iphoneos clang++ -arch armv7" export CFLAGS="-arch armv7 -target armv7-ios-darwin -march=armv7 -mcpu=cortex-a8 -mfpu=neon -mfloat-abi=softfp -Wno-unused-function -fstrict-aliasing -Oz -Wno-ignored-optimization-argument -isysroot ${sysroot} -fembed-bitcode -miphoneos-version-min=${ios_min_target} -I${sysroot}/usr/include" export LDFLAGS="-arch armv7 -target armv7-ios-darwin -march=armv7 -isysroot ${sysroot} -fembed-bitcode -L${sysroot}/usr/lib " export CXXFLAGS="-std=c++14 -arch armv7 -target armv7-ios-darwin -march=armv7 -mcpu=cortex-a8 -mfpu=neon -mfloat-abi=softfp -fstrict-aliasing -fembed-bitcode -miphoneos-version-min=${ios_min_target} -I${sysroot}/usr/include" ;; arm64) export CC="xcrun -sdk iphoneos clang -arch arm64" export CXX="xcrun -sdk iphoneos clang++ -arch arm64" export CFLAGS="-arch arm64 -target aarch64-ios-darwin -march=armv8 -mcpu=generic -Wno-unused-function -fstrict-aliasing -Oz -Wno-ignored-optimization-argument -isysroot ${sysroot} -fembed-bitcode -miphoneos-version-min=${ios_min_target} -I${sysroot}/usr/include" export LDFLAGS="-arch arm64 -target aarch64-ios-darwin -march=armv8 -isysroot ${sysroot} -fembed-bitcode -L${sysroot}/usr/lib " export CXXFLAGS="-std=c++14 -arch arm64 -target aarch64-ios-darwin -march=armv8 -mcpu=generic -fstrict-aliasing -fembed-bitcode -miphoneos-version-min=${ios_min_target} -I${sysroot}/usr/include" ;; arm64e) # -march=armv8.3 ???

针对Openssl的编译文件：

如果你只是需要一个Openssl最新版，那么恭喜你，上面的就够用了。但是如果你需要的是3.x以上版本，直接改上面脚本的版本号去编译，那么应该是编译不出库的。遇到问题不要慌，可以看output文件夹下的log，进去看，发现是bitcode在作祟，那么问题就好办了，修改通用文件（build-ios-common.sh）中:

表示支持Bitcode，对应工程中build setting中的bitcode YES -fembed-bitcode

删除掉该选项。然后再使用新的OpenSSL版本号，比如：3.1.0.测试是可以正常编译出静态库的。头文件需要在工程中去拷贝，也可以修改脚本一步到位。

这里再介绍一下编译静态库常用的一下命令：

xcrun -sdk iphoneos --show-sdk-path ／ xcrun -sdk iphonesimulator --show-sdk-path用来查找真机和模拟器SDK的路径； xcrun --find gcc / xcrun --find clang用来查找编译器的路径 -miphoneos-version-min选项指定最小支持的iOS版本 -fembed-bitcode选项开启bitcode的支持，去掉就不支持bitcode；
