[MichaelGDev48 (Michael G)]

When trying to install groff with universal variant it fails to configure

[ryandesign (Ryan Carsten Schmidt)]

The problems start at:

checking for working fcntl.h... no

which fails because:

We've seen this in tons of other ports already. See query:summary=~OSSwap to see a few, and look at the linked tickets in those tickets. Probably a defect in autoconf or gnulib or something else that goes into the creation of configure scripts, or alternately a defect in the macOS 11/12/13 SDKs. Not a defect in groff or the ports that are experiencing this build failure. We've worked around it in other ports by switching to the muniversal portgroup (which comes with its own set of difficulties).

is there a way i can specify to use macOS 10 sdk then?

[ryandesign (Ryan Carsten Schmidt)]

A macOS 10.x SDK would not support building for arm64.

In 291af0308e9648d59c6f0c02b55f17a85a3cf6f6/macports-ports (master):

groff: use muniversal

building universal on M1-era Macs fails. A check for a fix
that would allow one-pass universal building did not reveal a
straightforward solution.

Using muniversal works.
