How to add OpenSSL to an Xcode project
提问by Baruch
I am trying to port an application to mac OSX. It uses openssl. I am new to xcode and mac development. Do I need to compile and install openssl myself, or is there some equivalent of an openssl-devel package available as part of the OS or with homebrew or some such?
我正在尝试将应用程序移植到 mac OSX。它使用openssl。我是 xcode 和 mac 开发的新手。我是否需要自己编译和安装 openssl，或者是否有一些等效的 openssl-devel 软件包可作为操作系统的一部分或自制软件或类似软件提供？

You will need to compile and link it yourself, and your app needs to ship it. If the license of your app and OpenSSL's license are compatible, you may use static linking. Otherwise you will need to dynamically link it.
你需要自己编译和链接它，你的应用程序需要发布它。如果您的应用程序的许可证和 OpenSSL 的许可证兼容，您可以使用静态链接。否则，您将需要动态链接它。
There are a few documents describing the processand build scriptsthat you can find with Google searches. For iOS, there's even a Github project. I didn't copy the contents of those documents here since it's too much and it's a moving target.
您可以通过 Google 搜索找到一些描述过程和构建脚本的文档。对于 iOS，甚至还有一个Github 项目。我没有在这里复制这些文件的内容，因为它太多了，而且是一个移动的目标。
You can also install OpenSSL with Homebrew. If you just want to have your app run on your Mac and you don't want to distribute it, this is the easiest way: you just need to link it. But if you want to distribute your app, you would need to copy the library/libraries to your app bundle and make sure the the linker finds it there. This also has the disadvantage that there's a possible "disconnect" between your app and the OpenSSL version: if in one year, you update OpenSSL with Homebrew and want to compile/link an older version of your app against the very same OpenSSL version as you've used at that time, you have a problem.
您还可以使用 Homebrew 安装 OpenSSL。如果您只想让您的应用程序在您的 Mac 上运行而您不想分发它，这是最简单的方法：您只需要链接它。但是如果你想分发你的应用程序，你需要将库/库复制到你的应用程序包并确保链接器在那里找到它。这也有一个缺点，即您的应用程序和 OpenSSL 版本之间可能存在“断开连接”：如果在一年内，您使用 Homebrew 更新 OpenSSL 并希望针对与您完全相同的 OpenSSL 版本编译/链接旧版本的应用程序那个时候用过，你有问题。

- Download source from openssl source.
- Extract compressed file into directory of your choice. .
- Open command line and go to that directory and type something similar to
./configure darwin64-x86_64-cc. - Then type
make depend. - Then
make install. - Go to your Xcode project build settings. Under Header Search Paths add
/usr/local/ssl/includeand library search paths/usr/local/ssl/lib(or whatever install paths you chose in the configure step) . - Still in build settings go to Linking and under other linker flags put
-lssl -lcrypto
- 从openssl source下载源代码。
- 将压缩文件解压缩到您选择的目录中。.
- 打开命令行并转到该目录并键入类似于
./configure darwin64-x86_64-cc. - 然后键入
make depend。 - 然后
make install。 - 转到您的 Xcode 项目构建设置。在标题搜索路径下添加
/usr/local/ssl/include和库搜索路径/usr/local/ssl/lib（或您在配置步骤中选择的任何安装路径）。 - 仍在构建设置中转到链接并在其他链接器标志下放置
-lssl -lcrypto
You should be good to go now.
你现在应该可以走了。

i tried today starting of 2020
我今天尝试从 2020 年开始
install openssl with homebrew
使用自制软件安装 openssl
brew install openssl
this will install openssl version 1.1d in
这将安装 openssl 1.1d 版
/usr/local/Cellar/[email protected]/1.1.1d/lib/
add both libcrypto.a and libssl.a
添加 libcrypto.a 和 libssl.a
brew will not make a symbolic link to /usr/local/lib
brew 不会建立到 /usr/local/lib 的符号链接
