... which is an immediate problem for any build system, to be taken
seriously. i've posted on this previously (4 months ago, 5 months ago
and 8 months ago approximately), as well as there being an independent
post by someone who noted that modifications to one package required,
if memory serves correctly (which it usually doesn't) *six gigabytes*
of swap space in order to effect a link.
to repeat again: the example that i give is the one that i know well
- webkit, which requires at least 1.4gb *resident* RAM in order to
complete the link phase in a reasonable time frame. 15 minutes is not
unreasonable on a 2ghz dual-core XEON... *as long as* you do not
require debug information. if you require debug information (dbg deb
packages) then you're looking at around an hour.
if however you only have 1gb of RAM then that 15 minutes turns into
90 minutes, and christ knows what the debug build link time is, i
never bothered to find out because i have better things to do. and
that's with dual-core XEONs.
the debian ARM build systems which previously had only 1gb of RAM i
believe they were looking at 2 days for the link phase on some of
these larger packages.
so, yeah - word of advice from experience: *DO NOT* get a system with
1gb of RAM for building of distro packages, if you want to have a life
:)
