What happens when the software depends on some ancient, long solved bug that's maybe still in the old bundled version ? You'll have to support both the ancient bundled and the current deps, which over time increases maintenance overhead exponentially. > For a universal Linux build that has to run everywhere we can probably > at this stage definitely default to --with-system zlib, jpeg and some > other ones where the ABI have been stable for yonks and are ubiquitous. Is there any reason to have to still carry around ancient buggy bundled zlib ? Look, the generic case is a system which already has the required libs installed (or allows to install them trivially). Old legacy platforms are the specific cases. For those cases you can add some script that does a prefix build/install of the missing packages before building LO itself, and then creates a selfcontained blob package. > The clone dirs are split into libs-extern and libs-extern-sys, I imagine > the thinking at the moment is that one ones in libs-extern-sys are the > ones that would reasonably be expected to be preinstalled these days, > though f.e. Seems so. For example, openssl can be expected to exist on any sane system in our scope. And here it is *IMPORTANT* to use an up-to-date version. As an enterprise operator, I'd *NEVER* install any package that brings it's own (outdated) openssl copy, for essential security reasons. > a) hunspell sometimes changes its ABI to an Libo build against one > version of it may not be able to run against another. Always rebuild on the individual target distro's latest stable line. Modern distros support MVCC installations for such cases or have other mechanisms for solving such problems. > b) major version of icu always change their ABI, so a Libo build against > one e.g. icu 4.4 will not work if deployed against 4.2 etc. Exactly the case for an MVCC installation.
