Subject: autogen: build varies on usrmerge system

Date: Sat, 01 Feb 2020 01:16:05 -0800

[Message part 1 (text/plain, inline)]

Source: autogen
Severity: normal
Tags: patch
User: reproducible-builds@lists.alioth.debian.org
Usertags: usrmerge environment
X-Debbugs-Cc: reproducible-bugs@lists.alioth.debian.org

The paths for various binaries (grep, bash, sh) differ on a merged /usr
system, and autogen embeds those paths in several included
files.

The value of the SHELL environment variable also gets embedded into the
build when set.

The attached patch works around this in debian/rules by passing GREP,
POSIX_SHELL and SHELL to configure to ensure reproducible builds
regardless of environment or when build on a usrmerge system.

Thanks for maintaining autogen!

live well,
  vagrant

Hello Vagrant,

Thanks for the patch. Afaict it does not need bash but a posix shell:
---
config/libopts.m4
[while :
  do
      test -x "$POSIX_SHELL" && break
      POSIX_SHELL=`which bash`
      test -x "$POSIX_SHELL" && break
      POSIX_SHELL=`which dash`
      test -x "$POSIX_SHELL" && break
      POSIX_SHELL=/usr/xpg4/bin/sh
      test -x "$POSIX_SHELL" && break
      POSIX_SHELL=`/bin/sh -c '
          exec 2>/dev/null
          if ! true ; then exit 1 ; fi
          echo /bin/sh'`
      test -x "$POSIX_SHELL" && br
---

I will therefore use /bin/sh instead of /bin/bash.

cu Andreas
