Subject: build fails due to undefined reference to mpz_roinit_n
Date: Sat, 11 Aug 2018 18:45:25 -0400

Package: emacs
Version: 27.0.50

Since 78ec68e, builds on hydra.nixos.org fail with:

alloc.o: In function `make_pure_bignum':
  alloc.c:5570: undefined reference to `mpz_roinit_n'

A quick search suggests this function was added in gmp 6.
hydra is using gmp 5.1.3.
There is no gmp version test in configure.ac, and no option to force use
of mini-gmp.
This suggests builds on eg RHEL6 would fail in the same way.

This was fixed here:

commit da7fc851dc21342bd8f33f92771fe78087b73e35
Author: Paul Eggert <eggert <at> cs.ucla.edu>

  Reject old libgmp that lack mpz_roinit_n
  
  * configure.ac (HAVE_GMP): Port to RHEL 6.9, which has
  libgmp 3.5, which predates mpz_roinit_n.
