Re: GNU poke 2.90.0 on FreeBSD 12.0

[Bruno Haible]

On FreeBSD 12.0 / i386, I see a compilation error:

libtool: compile:  cc -ferror-limit=0 -DHAVE_CONFIG_H -I. 
-I../../../jitter/gnulib-local -I../config-private -I../jitter

This is due to a Gnulib bug, now fixed in Gnulib, see
https://lists.gnu.org/archive/html/bug-gnulib/2023-01/msg00200.html

To get the fix into poke, I would not recommend to upgrade to the
newest version on the master branch, since there were many commits
there recently and some of them may be destabilizing. Instead,
I would recommend to upgrade to the newest version on the 'stable-202301'
branch. You do this by adding these two lines to bootstrap.conf:

# Choose a specific version of gnulib, when checking out
GNULIB_REVISION=stable-202301
