I mean, I’ve read this:
The arch array should contain ‘i686′ and/or ‘x86_64′ depending on which architectures it can be built on. You can also use ‘any’ for architecture independent packages.
Which might make mine an obtuse question. I really don’t use PKGBUILDs beyond the few esoteric programs I prefer, that aren’t in Arch’s Community repository.
But short of cross-compiling, and therefore needing to physically change each field each time, there’s nothing in there that isn’t defined by /etc/makepkg.conf, or by the CARCH or CFLAGS variables.
Which means, to my thinking, that it’s just a flag that stops the process, if the CARCH field doesn’t match. Isn’t that just a variable checking a variable?
Of course, this is one of those things that just shows how little I know, and so I should probably keep my mouth shut. Seems to me that, in a distro with separate packages for each architecture, making another point of declaring the architecture again is a third time and not necessarily useful.
But I don’t know everything, so feel free to teach me. But it seems like that variable, along with some other things in PKGBUILDs, could be trimmed out. Spent too much time in Crux, I guess. …
P.S.: Yes, I know about customizepkg.
