Openssl errors when building the bitcoin-core on macOS

Question

I have been trying to build bitcoin-core on macOS as I am reading the "Mastering Bitcoin" book from Andreas Antonopoulos.

I read the instructions for building the the bitcoin-core on macOS from the doc/build-osx.md file in the bitcoin repository and I installed all the libraries that are needed ( following the build-osx.md file ):

brew install autoconf automake libtool boost miniupnpc openssl pkg-config protobuf qt ( Also I installed a bunch of other libraries that I hoped would solve the issue, such as sqlite python libevent qrencode
The docs say "You should see OpenSSL 1.0.1f 6 Jan 2014." however now we have version 1.1.1k in 2021 as I am writing this. And also it asked me to do brew link openssl --force which I did.
I installed berkeley-db4, but I did with brew install berkeley-db@4 since the link that is provided in the bitcoin docs doesn't work - brew install https://raw.github.com/mxcl/homebrew/master/Library/Formula/berkeley-db4.rb -–without-java
I have Xcode and its Command Line Tools
Then I did the ./autogen.sh , ./configure and make. The ./configure went alright, without any errors, however when I type make I get the following errors.

I thought it was something with the openssl version so I have been trying to fix it by installing an older version but brew gave me errors everytime I tried something new. Now I have the latest version of openssl which is 1.1.1k. I am not sure what I am doing wrong.

I would appreciate any help I can get. Thanks

What version of Bitcoin Core are you trying to build? Openssl is no longer a dependency since 0.20 — Andrew Chow, Aug 24 '21 at 22:53
I switched to v22.0rc2 and the problem seems to have been fixed. Thank you. — Alex Matei, Aug 25 '21 at 11:21
