Hi all,
On Friday was started SUSE's Hackweek 14. Peter Simons and I working on project named " Automate Haskell Packaging" -- https://hackweek.suse.com/14/projects/1368
One of project result is proposal to globally enable macro "%ghc_without_dynamic 1" which causes all Haskell Apps -- binary packages like "pandoc" , "git-annex" will be build with staticaly linked binaries. As result user instaling only this package not need install full haskell stack.
Any comments, suggestions to this Proposal?
PRO: binary with very small amount of deps, Very fast start of packages
Do we have any benchmarks on the start up speed?
CONS: very big binaries --> for example git-annex
This part I worry about. How many statically linked apps are we talking about, and how much size will we add overall?
all haskell libraries before used as shared after change will be part of app binary, so for examaple pandoc.rpm -- dynamically linker about 0.5 MB , statically 7MB but diferrence in requires: static package> https://build.opensuse.org/package/binary/home:mimi_vx:static/pandoc?arch=x86_64&filename=pandoc-1.17.1-2.1.x86_64.rpm&repository=openSUSE_Tumbleweed vs dynamic package> https://build.opensuse.org/package/binary/devel:languages:haskell/pandoc?arch=x86_64&filename=pandoc-1.17.1-28.8.x86_64.rpm&repository=openSUSE_Tumbleweed --> user of pandoc practically installs only pandoc.rpm itself ... and not bazzilion of libraray packages :) of course if You want a devel packages it installs all ghc-package libraries ..
I find the idea of statically linked Pandoc interesting, but I'm not sure if the benefits outweigh the disadvantages. It might make sense if we want to create a "stable" Pandoc for instance that gets rebuilt/relinked less often than the rest of the libraries. It could reduce regressions. But if Pandoc and the other apps will get rebuilt/relinked with the rolling library updates, then we don't gain in that respect.
