After compiling and installing GNU automake 1.15, I get this error whenever I run automake:
Unescaped left brace in regex is deprecated, passed through in regex;
marked by <-- HERE in m/\${ <-- HERE ([^ \t=:+{}]+)}/
at /usr/local/bin/automake line 3936
I am running perl v5.22.0.

Also because @bill-cole's answer is most relevant. – Derrell Durrett Feb 18 '18 at 18:51
