鸿蒙 openssl

一、前期准备

  1. 从 openHarmony SDK 官方发布渠道下载 SDK。
    我下载的版本是 version-Master_Version-OpenHarmony_4.1.6.5_dev-20240127_020213-ohos-sdk-full.tar.gz
    解压 SDK，得到 ohos_sdk 目录。可以看到 Linux 和 windows 两个平台的 SDK 目录，我们进入 Linux 目录。
ohos@ubuntu20:~/tools/OH_SDK$ cd ohos-sdk
ohos@ubuntu20:~/tools/OH_SDK/ohos-sdk$ ls
linux  windows
ohos@ubuntu20:~/tools/OH_SDK/ohos-sdk$ cd linux/
ohos@ubuntu20:~/tools/OH_SDK/ohos-sdk/linux$ ls
ets-linux-x64-4.0.1.2-Canary1.zip  native-linux-x64-4.0.1.2-Canary1.zip     toolchains-linux-x64-4.0.1.2-Canary1.zip
js-linux-x64-4.0.1.2-Canary1.zip   previewer-linux-x64-4.0.1.2-Canary1.zip

  1. 解压 Linux 环境下的 OHOS SDK 工具包，得到对应工具目录。由于我们是 c/c++ 库的编译，我们只需要关注 native 目录，将其解压即可。

二、使用 ohos-sdk 编译 OpenSSL 库

  1. 下载 openssl 官方源码，我使用的版本是3.0.12。
    设置需要的编译工具链环境变量。这里设置的是 ohos64bit 库的编译工具链，如果需要编译 ohos32bit 库请设置为 32bit 编译工具链。
ohos@ubuntu20:~/openHarmony/openssl$ export OHOS_SDK=/home/ohos/tools/OH_SDK/ohos-sdk/linux #这里根据自己的SDK解压目录设置
ohos@ubuntu20:~/openHarmony/openssl$ export AS=${OHOS_SDK}/native/llvm/bin/llvm-as
ohos@ubuntu20:~/openHarmony/openssl$ export CC="${OHOS_SDK}/native/llvm/bin/clang  --target=aarch64-linux-ohos"
ohos@ubuntu20:~/openHarmony/openssl$ export CXX="${OHOS_SDK}/native/llvm/bin/clang++  --target=aarch64-linux-ohos"
ohos@ubuntu20:~/openHarmony/openssl$ export LD=${OHOS_SDK}/native/llvm/bin/ld.lld
ohos@ubuntu20:~/openHarmony/openssl$ export STRIP=${OHOS_SDK}/native/llvm/bin/llvm-strip
ohos@ubuntu20:~/openHarmony/openssl$ export RANLIB=${OHOS_SDK}/native/llvm/bin/llvm-ranlib
ohos@ubuntu20:~/openHarmony/openssl$ export OBJDUMP=${OHOS_SDK}/native/llvm/bin/llvm-objdump
ohos@ubuntu20:~/openHarmony/openssl$ export OBJCOPY=${OHOS_SDK}/native/llvm/bin/llvm-objcopy
ohos@ubuntu20:~/openHarmony/openssl$ export NM=${OHOS_SDK}/native/llvm/bin/llvm-nm
ohos@ubuntu20:~/openHarmony/openssl$ export AR=${OHOS_SDK}/native/llvm/bin/llvm-ar
ohos@ubuntu20:~/openHarmony/openssl$ export CFLAGS="-fPIC -D__MUSL__=1"
ohos@ubuntu20:~/openHarmony/openssl$ export CXXFLAGS="-fPIC -D__MUSL__=1"

  1. 执行 Configure 构建脚本。
ohos@ubuntu20:~/openHarmony/openssl$ ./Configure linux-aarch64 --prefix=/home/ohos/openHarmony/openssl_install
		# 在需要选择系统的时候由于configure不识别ohos，因此我们需要使用Linux aarch64等价系统和cpu架构 为了方便打包，需要指定安装目录
Configuring OpenSSL version 1.1.1t (0x1010114fL) for linux-aarch64

三、使用 ohos-sdk 编译 Poco 库

  1. SDK 采用 cmake 作为默认的编译脚本工具和 DevEco 开发工具是一致的。
    下载 Poco 官方源码，建议使用版本是 1.12.6。如果使用1.12.4版本，会导致编译出的 libPocoCrypto.so 无法正常使用上述版本的 OpenSSL 库。
  2. 进入 poco-poco-1.12.6 目录，创建 ohos64build 目录（存放构建文件）。执行 cmake，生成 makefile。
root@kw:~/d# cd poco-poco-1.12.6
root@kw:~/d/poco-poco-1.12.6# mkdir ohos64build&&cd ohos64build

注意：
首先，这里执行的 cmake 是 SDK 内的 cmake，不是你自己系统上原有的 cmake。包括 toolchain file 也是 SDK 内的。所以在编译 OpenSSL 库时，要将 --prefix 设置为 /ohos-sdk/linux/native/sysroot/usr
其次，cmake执行的过程中，一定要确保出现：
– Found OpenSSL: /root/d/ohos-sdk/linux/native/sysroot/usr/openssl/lib/libcrypto.so
– Building: NetSSL_OpenSSL
– Building: Crypto
ENABLE_CRYPTO:BOOL=ON
ENABLE_NETSSL:BOOL=ON

  1. 编译出 Poco 库。
root@kw:~/d/poco-poco-1.12.6/ohos64build# make -j2

  • 1
  1. 使用 file 命令，查看编译出的 elf 文件的属性。可以看到动态库和可执行程序都是 ARM aarch64 架构的。ohos cmake toolchainfile 在不设置 cpu 架构时默认为 aarch64。如果你需要编译 arm32，需要在 cmake 时加上参数 -DOHOS_ARCH=armeabi-v7a
