dyld_libssl_libcrypto_not_found.md

socat fails with dyld library not found. This hack worked like a charm!

These are 2 different errors I executed when I was trying to setup a port 80 listener

sudo socat -d -d TCP-LISTEN:80,fork TCP:$(ipconfig getifaddr en0):31000
dyld: Library not loaded: /usr/local/opt/openssl/lib/libssl.1.0.0.dylib
  Referenced from: /usr/local/bin/socat
  Reason: image not found
Abort trap: 6

and

sudo socat -d -d TCP-LISTEN:80,fork TCP:$(ipconfig getifaddr en0):31000
dyld: Library not loaded: /usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib
  Referenced from: /usr/local/bin/socat
  Reason: image not found

This is how you fix libssl

Of course, you have to verify libssl.1.1.dylib specifically the file you have in your system.

sudo ln -s /usr/local/opt/openssl/lib/libssl.1.1.dylib /usr/local/opt/openssl/lib/libssl.1.0.0.dylib

This is how to fix libcrypto

You should have an existing libcrypto.1.1.dylib. Check the version you have in your system.

sudo ln -s /usr/local/opt/openssl/lib/libcrypto.1.1.dylib /usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib
