Specifically, the fact that `makepkg -s` will only use global values, so any override in "depends" or "optdepends" inside a split package's packaging function will not be used, and therefore should probably be included in "makedepends" (Else build could fail e.g. in a clean chroot) Signed-off-by: Olivier Brunel --- So I'm assuming this isn't really a bug, but a known limitation of makepkg. Once I figured out what was happening and why, I looked into it and couldn't find any documentation about said limitation (unless I missed something obvious?), but looking at some official PKGBUILDs it seems to be known, although sometimes it's a bit "tricky" to figure out. E.g. if you look at php, you won't find pcre nor libxml2 in makedepends, even though they're required for building. One could assume makepkg will install them due to their presence in depends inside package_XXX() functions, while they actually get installed because apache (which depends on pcre) and libxslt (which depends on libxml2) are in makedepends. Others, e.g. unixodbc or sqlite, are listed both in makedepends and as depends in some package_XXX() functions. Looking into this, I also found this old blog post[1] of Allan's, introducing split packages, where he says: "As a general rule, almost every package in the split packages depends array should probably be present in the global makedepends array." No mention of "why"/makepkg's limitation, though. I'm assuming it was/is rather obvious to you guys, but wasn't to me, and I couldn't find a similar recommendation in the doc, hence the patch.
