Some months ago I asked whether patching or rerunning the auto* tools was the better method when modifying build files in a spec file. This question is for those that thought that using the auto* tools was the right way to go. I've recently run across autoreconf [1]_ in the autoconf toolset and wondered if the best way to rebuild build scripts would be something like:: %setup # Patch to configure.in, Makefile.am, etc %patch0 -p1 %build autoreconf ... Is this cleaner than using libtoolize --force or autogen.sh? If so, are there some options that would be appropriate to always pass to autoreconf? --force --install seem like likely candidates.
