From 9e13aab19135c2013a2a2540e106d4c15eb8a63d Mon Sep 17 00:00:00 2001 From: David Young Date: Thu, 3 Oct 2019 11:12:32 -0500 Subject: Not every system has perl installed in /usr/bin/, so change the shebang (#!) line to `/usr/bin/env perl` to locate perl on the PATH. Everything after the first pathname in the shebang line is treated as a single argument to the command interpreter (/usr/bin/env "perl -w"), and there is not ordinarily any such program as "perl -w". So if the old shebang line used an option such as `-w`, add a `use warnings;` statement to the script---note that the semantics change slightly. `bin/destdep` uses a trick to pass `-p` to `/usr/bin/env perl`. It couldn't hurt to use the same trick to pass `-w`. With these changes, `sh autogen.sh` runs on NetBSD. It ought to still work on every other system HDF5 supports, too. --- bin/checkapi | 4 +++- bin/checkposix | 3 ++- bin/debug-ohdr | 2 +- bin/dependencies | 4 +++- bin/distdep | 5 ++++- bin/errors | 3 ++- bin/iostats | 2 +- bin/make_err | 3 ++- bin/make_overflow | 3 ++- bin/make_vers | 3 ++- bin/runbkgprog | 3 ++- bin/trace | 3 ++- 12 files changed, 26 insertions(+), 12 deletions(-) diff --git a/bin/checkapi b/bin/checkapi index 6882dea..f5dcacc 100755 --- a/bin/checkapi +++ b/bin/checkapi @@ -1,4 +1,4 @@ -#!/usr/bin/perl -w +#!/usr/bin/env perl # # Copyright by The HDF Group. # Copyright by the Board of Trustees of the University of Illinois. @@ -13,6 +13,8 @@ # require 5.003; +use warnings; + # Purpose: insures that API functions aren't called internally. # Usage: checkapi H5*.c my $filename = ""; diff --git a/bin/checkposix b/bin/checkposix index 30128e3..233d15c 100755 --- a/bin/checkposix +++ b/bin/checkposix @@ -1,5 +1,6 @@ -#!/usr/bin/perl -w +#!/usr/bin/env perl require 5.003; +use warnings; # # Copyright by The HDF Group. diff --git a/bin/debug-ohdr b/bin/debug-ohdr index 5b0a4b3..1363456 100755 --- a/bin/debug-ohdr +++ b/bin/debug-ohdr @@ -1,4 +1,4 @@ -#!/usr/bin/perl +#!/usr/bin/env perl # # Copyright by The HDF Group. # Copyright by the Board of Trustees of the University of Illinois. diff --git a/bin/dependencies b/bin/dependencies index 82247da..367351a 100755 --- a/bin/dependencies +++ b/bin/dependencies @@ -1,4 +1,4 @@ -#!/usr/bin/perl -w +#!/usr/bin/env perl # # Copyright by The HDF Group. # Copyright by the Board of Trustees of the University of Illinois. @@ -11,6 +11,8 @@ # If you do not have access to either file, you may request a copy from # help@hdfgroup.org. # +use warnings; + my $depend_file; my $new_depend_file; my $srcdir; diff --git a/bin/distdep b/bin/distdep index 4643700..cd310e0 100755 --- a/bin/distdep +++ b/bin/distdep @@ -1,4 +1,7 @@ -#!/usr/bin/perl -p +#!/bin/sh +#! -*-perl-*- +eval 'exec perl -p -x -S $0 ${1+"$@"}' + if 0; # # Copyright by The HDF Group. # Copyright by the Board of Trustees of the University of Illinois. diff --git a/bin/errors b/bin/errors index 3c99fdc..107bb9c 100755 --- a/bin/errors +++ b/bin/errors @@ -1,5 +1,6 @@ -#!/usr/local/bin/perl -w +#!/usr/bin/env perl require 5.003; +use warnings; use Text::Tabs; # NOTE: THE FORMAT OF HRETURN_ERROR AND HGOTO_ERROR MACROS HAS diff --git a/bin/iostats b/bin/iostats index f054b9c..e389992 100755 --- a/bin/iostats +++ b/bin/iostats @@ -1,4 +1,4 @@ -#!/usr/bin/perl +#!/usr/bin/env perl # # Copyright by The HDF Group. # Copyright by the Board of Trustees of the University of Illinois. diff --git a/bin/make_err b/bin/make_err index 623c1b6..7f38591 100755 --- a/bin/make_err +++ b/bin/make_err @@ -1,6 +1,7 @@ -#!/usr/bin/perl -w +#!/usr/bin/env perl require 5.003; $indent=4; +use warnings; # # Copyright by The HDF Group. diff --git a/bin/make_overflow b/bin/make_overflow index ccd640e..cee0126 100755 --- a/bin/make_overflow +++ b/bin/make_overflow @@ -1,6 +1,7 @@ -#!/usr/bin/perl -w +#!/usr/bin/env perl require 5.003; use strict; +use warnings; # Global settings diff --git a/bin/make_vers b/bin/make_vers index 4de2dbd..8316393 100755 --- a/bin/make_vers +++ b/bin/make_vers @@ -1,5 +1,6 @@ -#!/usr/bin/perl -w +#!/usr/bin/env perl require 5.003; +use warnings; # Global settings # (The max_idx parameter is the only thing that needs to be changed when adding diff --git a/bin/runbkgprog b/bin/runbkgprog index 69fa2d0..f04ea89 100755 --- a/bin/runbkgprog +++ b/bin/runbkgprog @@ -1,5 +1,6 @@ -#!/usr/bin/perl -w +#!/usr/bin/env perl require 5.003; +use warnings; $indent=4; # diff --git a/bin/trace b/bin/trace index 3cae0a4..34bcd3a 100755 --- a/bin/trace +++ b/bin/trace @@ -1,4 +1,4 @@ -#!/usr/bin/perl -w +#!/usr/bin/env perl ## # Copyright by The HDF Group. # Copyright by the Board of Trustees of the University of Illinois. @@ -12,6 +12,7 @@ # help@hdfgroup.org. ## require 5.003; +use warnings; $Source = ""; ############################################################################## -- cgit v0.12
