main failing on macOS 13

[Greg Troxel]

I see in config.log:
./configure: line 114: config_cflags[@]: unbound variable

and I think this is about new-enough gmake. make is gmake but it's
really old.

I am unclear on how configure finds make vs gmake and chooses.

I am able to build on macOS 15.

Yes, I know macOS 13 is out of support...

It doesn't now, it's just whatever make you invoke.

Assuming brew or similar still works there, it wouldn't be unreasonable
to just say that you need to "brew install ..." there.

And if it is the make version, then we should probably add whatever the
requirement is to the README.

I think I'm confused and this is about new enough *bash*.

pkgsrc works fine, and I do have new gmake.

Will send a patch when I figure it out, but from your comments I lean to
"old bash".

[Greg Troxel]

My problem was not gmake; it's that bash 3 included with macOS is too
old for the newfangled bashisms in main-branch configure. Using
/bin/bash on macOS 15 and 0.33.x works.

I sent a patch, twice :-( The first version has a whitespace error and
lacks signed-off-by.
