Please attach the main.log.

Checking on my system, I see it's the usual implicit declaration of function problem with Xcode 12.

In the future, please fill in the Port field.

Replying to mf2k:

In the future, please fill in the Port field.

I am a bit confused. I filled in the Port field, indicating "macports".

I followed the instructions on ​https://guide.macports.org/#project.tickets.

This is the text given in that section:

Port: For tickets on ports, enter the name of the port (or ports, space-separated, when multiple are affected).

Or do I misunderstand?

[mf2k (Frank Schima)]

You misunderstood.

[hpauluss (hpauluss)]

Replying to mf2k:

You misunderstood.

Yes, you are right. Sorry.

Now I've understood.
