<p>This is a known deficiency of how Apple rushed adding support for
their M1 ARM Desktop CPU to the XCode build suite.</p>
<p>When building a desktop macOs program file with XCode, it will
implicitly try to build both an x86_64 and an arm64 variant, and
will get very surprised your compiled open source library files
contain only code for one of those architectures.</p>
<p>A potential workaround is to build OpenSSL for all 3 macOs
desktop architectures and combine them with the "lipo" tool to
create a "fat library". The major shortcoming of this is that
they use the same architecture "key" value for macOs and iOs, but
require the libraries to be compiled differently (because the ABI
for some system functions differ). Before the M1 merge, this
would work thanks to arm64 always being iOS hardware and x86_64
always being macOs hardware. A workaround for that is to create a
separate set of library files for iOS (including iOS emulator on
x86-family desktops) and macOs (including x86-family and arm64
architectures), then being careful to reference the right set for
each project. Unfortunately, there is no workaround to use the
same set of library files for iOS on arm64 mobile hardware and iOS
emulator on arm64 desktop hardware.<br>
