Hi all, i have a little issue with autoconf and epel-5 the statement of the problem: in configure.ac stands: CXXFLAGS="-Wall -O2" to honor the rpmoptflags i removed this line and create a patch of my changes. now i have to run autoconf to implement my changes. no problem in fedora. in epel-5 it will abort: http://buildsys.fedoraproject.org/logs/fedora-5-epel/1476-hosts3d-0.97-3.el5/i386/build.log my idea to handle this problem is: 1) run autoconf in fedora and create a diff of the changes (as patch1) 2) handle it in the specfile: %if 0%{?fedora} BuildRequires: autoconf %endif %prep %setup -q -n %{name}-%{srcversion} # Patch to remove CXXFLAGS from configure.ac %patch0 -p1 %if 0%{?rhel} # Patch for autoconf 2.60 %patch1 -p1 %endif %build %if 0%{?fedora} autoconf %endif is this the right way to solve this problem? i didn't found a helpful text passage in the packaging-guidelines -- Mit freundlichen Grüßen aus dem schönen Hainzell Simon Wesp -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
