those last years i installed guile on at least 3 mac system,without problem
with read line
readline installed by homebrew ,the homebrew version seems to use gnu
readline:
https://formulae.brew.sh/formula/readline
https://tiswww.case.edu/php/chet/readline/rltop.html
simply by adding that:
(use-modules (ice-9 readline))
(activate-readline)
so i surprised of this problem,
but again with homebrew it is perhaps better to install from the source
too, i will try tomorrow...

i succeed in making work the first part of this :
https://www.gnu.org/software/guile/manual/html_node/C-Extensions.html

with a few modifications:
gcc `pkg-config --cflags guile-3.0` -shared -o libbessel.so -fPIC
 -lguile-3.0 bessel.c

instead of:

gcc -shared -o libbessel.so -fPIC bessel.c

perhaps updating the doc

Regards,

Damien
