From 4fc573e2f3cbbed7baa5e05fb798c2e4f4236f7d Mon Sep 17 00:00:00 2001 From: Emil Velikov Date: Tue, 14 Feb 2017 11:38:20 +0000 Subject: Rework CHANGELOG_CMD to touch/echo >&2 only as needed Currently CHANGELOG_CMD issues a touch ChangeLog; echo "Scary message" >&2 even if the file is already present. For example, when running `make distcheck' the following is observed: " /bin/sh: ../../.changelog.tmp: Permission denied git directory not found: installing possibly empty changelog. ... /bin/sh: ../../.changelog.tmp: Permission denied git directory not found: installing possibly empty changelog. " That in itself happens since srcdir is RO, thus shell redirection [to srcddir/.changelog.tmp] fails. At the same time the latter message is wrong and misleading since the file is already there, with the correct contents. Silence the permissing warning (/dev/null is our friend), and add a simple `test -e .../ChangeLog || (...' prior to the touch/echo combo. As we're here also update the message to be more generic, since there are multiple other reasons why things can fail.
