See also Debian bug#659482: <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=659482> Since automake 1.11.2, aclocal no longer succeeds if the system acdir ("${datadir}/aclocal", i.e., "/usr/share/aclocal" when ${prefix} is "/usr") does not exist. Unfortunately, this causes at least Debian's "make" package to FTBFS under the minimal chroot environment "cowbuilder", because autoreconf somehow ends up being called there when /usr/share/aclocal is not present. Now, this is mostly the fault of cowbuilder, since it's likely it is it that removes the automake-created but empty /usr/share/aclocal directory when creating the chroot where the build is performed. Still, we can easily work around this issue by creating the system acdir with some "real content" from the start: a README files that explains what the directory is there for, and tell not to remove it. And in hindsight, doing so seems like a good idea, independently from the cowbuilder issue, since it's not that nice to just create what might appear as an empty random directory, but which will utterly break the package when removed. * m4/acdir/README: New file. * m4/Makefile.am (dist_system_ac_DATA): Add it. * m4/acdir/.placeholder: Delete, no more needed. * m4/Makefile.am (EXTRA_DIST): Remove it. * THANKS: Update. --- THANKS | 1 + m4/Makefile.am | 5 ++--- m4/acdir/.placeholder | 2 -- m4/acdir/README | 6 ++++++ 4 files changed, 9 insertions(+), 5 deletions(-) delete mode 100644 m4/acdir/.placeholder create mode 100644 m4/acdir/README diff --git a/THANKS b/THANKS index 36f8f4b..7b7c9df 100644 --- a/THANKS +++ b/THANKS @@ -360,6 +360,7 @@ Thomas Tanner tan...@ffii.org Toralf Förster toralf.foers...@gmx.de Tim Goodwin t...@star.le.ac.uk Tim Mooney moo...@dogbert.cc.ndsu.nodak.edu +Tim Retout dioc...@debian.org Tim Rice t...@multitalents.net Tim Van Holder tim.van.hol...@pandora.be Toshio Kuratomi tos...@tiki-lounge.com diff --git a/m4/Makefile.am b/m4/Makefile.am index 2f5ead3..c281e28 100644 --- a/m4/Makefile.am +++ b/m4/Makefile.am @@ -55,10 +55,9 @@ tar.m4 \ upc.m4 \ vala.m4 -# So that $(system_acdir) will be created by "make install". -dist_system_ac_DATA = +dist_system_ac_DATA = acdir/README -EXTRA_DIST = acdir/.placeholder amversion.in +EXTRA_DIST = amversion.in # We build amversion.m4 here, instead of from config.status, # because config.status is rerun each time one of configure's diff --git a/m4/acdir/.placeholder b/m4/acdir/.placeholder deleted file mode 100644 index 8dd7f67..0000000 --- a/m4/acdir/.placeholder +++ /dev/null @@ -1,2 +0,0 @@ -This file is here only to ensure the directory containing it exists -in the git repository, and goes in the distribution tarball. diff --git a/m4/acdir/README b/m4/acdir/README new file mode 100644 index 0000000..d3a25e7 --- /dev/null +++ b/m4/acdir/README @@ -0,0 +1,6 @@ +This directory is where .m4 files providing third-party autoconf +macros can be placed to be automatically found by the aclocal(1) +program. + +This directory, even if empty, is required in order for aclocal to +work properly.
