How to: Build OpenSSL 0.9.8zh on macOS

Intro

This folder is just to try compiling OpenSSL 0.9.8zh für x86-64 and arm64.
It requires a manual change in 'Configuration' to be able to build. That's because that version is outdated, and doesn't containt a build configuration for darwin64-arm64. So don't use this for production!

Let's build OpenSSL 0.9.8zh

1. Extract the downloaded openssl-0.9.8zh.tar.gz
2. Search for the line in Configuration containing:
   darwin64-x86_64-cc
3. duplicate that line
4. in that duplicated line: replace the following:

   darwin64-x86_64-cc   ->   darwin64-arm64-cc  
   arch x86_64          ->   arch arm64
   
5. Copy the modified file Configuration next to the build.sh and rename it to Configure_098_arm64
6. Note: build.sh will replace the Configuration with your modified version for the arm64 build.

Note: The OpenSSL API is different in 0.9.8 compared to 1.1.x and 3.0.x.
Even just getting the OpenSSL Version requires different calls...
See the example project, which includes several OpenSSL Versions.
