From 5b574542070db286c89b3827e8f15ed4b3b39034 Mon Sep 17 00:00:00 2001 From: Robert Yang Date: Thu, 6 Apr 2017 01:46:00 -0700 Subject: [PATCH] replace "perl -w" with "use warnings" The shebang's max length is usually 128 as defined in /usr/include/linux/binfmts.h: #define BINPRM_BUF_SIZE 128 There would be errors when @PERL@ is longer than 128, use '/usr/bin/env perl' can fix the problem, but '/usr/bin/env perl -w' doesn't work: /usr/bin/env: perl -w: No such file or directory So replace "perl -w" with "use warnings" to make it work.
