Subject: [Buildroot] popt build failing during autoreconf
Message-ID: <q132am$sni$1@blaine.gmane.org>

The popt package has recently started failing to build during the
autoreconf step.  I've been using buildroot-2016.11.2, but I tried
updating the popt package files to those from git-master, and it still
fails the same way.  This appears to be an incompatibility between
automake and perl 5.26:

  $ ./output/host/usr/bin/automake --version
  Unescaped left brace in regex is illegal here in regex; marked by <-- HERE in m/\${ <-- HERE ([^ \t=:+{}]+)}/@./output/host/usr/bin/automake line 3936.

It appears that buildroot-2016.11.2 is using automake 1.15, and the
current git buildroot master branch is using version 1.15.1.  Should I
be able to update the automake package without causing problems?
