Naming a directory 'core' is dangerous and non-portable, because the name 'core' is traditionally reserved for core dumps. Similarly, naming a directory 'aux' is dangerous and non-portable, because the name 'aux' opens a special device on Windows. Similarly, naming two files with a case-sensitive clash is unsupported. In short, autoconf sticks with the philosophy that it is better for you to name your files portably than for autoconf to bend over backward to special case when those non-portable names exist on platforms where they happen to work, but will fall apart on platforms where they do not work. > > Special rules (i.e., no 'core' directories) that can only be found by > grepping mailing lists also seems to be less than desirable. If you think we need to more fully document that both 'core' and 'aux' are recommended to be avoided in your project, patches are welcome. > > What happens if a user aliases `rm` to `rm -rf`? Precisely why we are suggesting that you should fix your package to avoid 'core' as a directory, and not that we fix 'autoconf' to bend over backwards to support this fringe case. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
