I am building the libpng arpm from rawhide on a highly modified CentOS 6.4 box with autoconf 2.65. rpmbuild -ba fails because autoconf is not >= 2.68. Therefore the line in the spec should read: BuildRequires: autoconf >= 2.68 Full error message I get is below: Executing(%build): /bin/sh -e /var/tmp/rpm-tmp.K3Ireu + umask 022 + cd /home/mono/rpmbuild/BUILD + cd libpng-1.6.3 + autoreconf -vi autoreconf: Entering directory `.' autoreconf: configure.ac: not using Gettext autoreconf: running: aclocal -I scripts configure.ac:17: error: Autoconf version 2.68 or higher is required configure.ac:17: the top level autom4te: /usr/bin/m4 failed with exit status: 63 aclocal: /usr/bin/autom4te failed with exit status: 63 autoreconf: aclocal failed with exit status: 63 error: Bad exit status from /var/tmp/rpm-tmp.K3Ireu (%build) RPM build errors: Bad exit status from /var/tmp/rpm-tmp.K3Ireu (%build)
After discussion with our autoconf expert row were changed to: BuildRequires autoconf >= 2.68 But current version of autoconf in rawhide is 2.69. scm-commit (https://lists.fedoraproject.org/pipermail/scm-commits/Week-of-Mon-20130923/1117727.html) -> CLOSED RAWHIDE
