I didn't go into all the details about how the --with/--without options work. I started to write more in my initial reply, but then I thought I was getting too deep in the weeds, so I dropped that. ;) For a little more detail on it, the kernel isn't doing anything special there with regards to --with/--without. They're doing essentially what the %bcond_with/out macros do. In /usr/lib/rpm/macros, %bcond_with and %bcond_without are defined like this: %bcond_with() %{expand:%%{?_with_%{1}:%%global with_%{1} 1}} %bcond_without() %{expand:%%{!?_without_%{1}:%%global with_%{1} 1}} They're really just shortcuts for setting %with_$foo and related macros. You can read more in the macros file, starting around line 104 in rpm-4.14.0: https://github.com/rpm-software-management/rpm/blob/rpm-4.14.0-release/macros.in#L104 It's a lot of macro work there, but it boils down to making things easier for packages to use the %bcond macros and the --with/--without command line arguments. Even the command line arguments are just shortcuts to define %_with_$foo and %_without_$foo macros. Hopefully that's at least mildly interesting and/or useful information. More importantly, I hope I managed to sum it up reasonably, without any major errors. ;) -- Todd ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If God had meant for us to be naked, we would have been born that way.
