Hi,
We skipped autoconf 2.64 and now 2.65 brings some unpleasant suprises to quite some packages. From what I read the build logs, most fail because of the change explained here:
http://www.gnu.org/software/hello/manual/autoconf/Expanded-Before-Required.h...
So if your package runs autoconf during build, then either stop doing that and rely on the configure script provided or look out for warnings like this:
configure.in:32: warning: AC_REQUIRE: `AC_PROG_CC' was expanded before it was required ./../lib/autoconf/c.m4:429: AC_LANG_COMPILER(C) is expanded from... ./../lib/autoconf/lang.m4:316: AC_LANG_COMPILER_REQUIRE is expanded from... ./../lib/autoconf/general.m4:2573: AC_COMPILE_IFELSE is expanded from... ./../lib/autoconf/general.m4:2581: AC_TRY_COMPILE is expanded from...
This means autoconf will expand the macro twice and that can generate quite funny errors later in the build.
Often the easiest fix is to drop the call to autoreconf from the
%build section. It is usually not necessary (and sometimes even
a bad idea) to do autoreconf with a different autoconf version
than upstream used. Even most patches are trivially also applied
to the generated files.
Thanks,
Richard.
