Thanks for the tip!
So I tried the following:
./cgminer -o stratum+tcp://solo.ckpool.org:3333 -u (my wallet address) -p x
and I get the following output:
[2021-02-20 20:02:41.038] Started cgminer 4.11.1
[2021-02-20 20:02:41.040] Probing for an alive pool

As I am not that interested in solo mining and I would prefer to do it in a pool (but at this point I'll take anything!) I tried the following:
./cgminer -o stratum+tcp://ca.stratum.slushpool.com:3333 -u (my slushpool user ID) -p x
and
./cgminer -o stratum+tcp://ca.stratum.slushpool.com:3333 -u (my wallet address) -p x (I also tried with my slushpool password)
and get the following:
[2021-02-20 19:58:22.127] Started cgminer 4.11.1
[2021-02-20 19:58:22.128] Probing for an alive pool

What am I doing wrong?
