Re: Packaging my first haskell package
Hi Andreas,
I'm not an haskell man, but haskell is in a "permanent transition" state.
Particularly, some days ago, ghc 7.10 reached unstable, and now a lot of packages needs
binNMU and source uploads (from experimental mainly), to make things settle down again.
this will take a lot of time (maybe weeks?), so I might suggest you to build from testing maybe, and check
from time to time if everything works in unstable too.
https://release.debian.org/transitions/html/haskell.html
and
https://people.debian.org/~nomeata/binNMUs-haskell.txt
might help in finding what is currently uninstallable.
(follow the list to understand why an easy experimental->unstable->testing transition is not possible, e.g. because of armel removal request
waiting for ftp-masters, and a lot of rebuilds that are currently failing).
I hope things will be better soon :)
cheers!

Hi,
I need to dive into Haskell packaging from scratch since there was a
request of a Debian Med user to package PhyBin[1]. I started with
cabal-debian which created a basic packaging dir which I changed to some
extend. I pushed my results to the Debian Med packaging Git[2] which is
writable to any DD (so feel free to commit patches there if this
simplifies things).
I also need to add that I intend to backport the package to Jessie which
might add some extra effort since I noticed that one of the dependencies
(libghc-prettyclass-*) is not available in Jessie and besides this it is
quite tricky to install a mix of Haskell packages from Jessie and
Jessie-backports.
I'm also aware that libghc-hierarchical-clustering-* is not even
available in unstable but cabal-debian has added this to the
Build-Depends. I guess I need to package this as well.
However, my main problem is currently that the template does not even
build if I uncomment the currently missing Build-Depends and I'm running
into
...
The following packages have unmet dependencies:
libghc-vector-prof : Depends: libghc-primitive-prof-0.6-61138 which is a virtual package and is not provided by any available package.
libghc-vector-dev : Depends: libghc-primitive-dev-0.6-61138 which is a virtual package and is not provided by any available package.
pbuilder-satisfydepends-dummy : Depends: libghc-text-dev (< 0.12) but 1.2.1.3-2 is to be installed.
Depends: libghc-text-prof (< 0.12) but 1.2.1.3-2 is to be installed.
Depends: libghc-text-doc (< 0.12) but 1.2.1.3-2 is to be installed.
Unable to resolve dependencies! Giving up...

when trying to build [2] using `gbp buildpackage` in a pbuilder chroot.
I need to admit that I have no idea about the complex relations between
the system of differently versioned set of real and virtual packages and
how to proceed from here.
On a Jessie system I managed at least to manually install the existing
dependencies after pinning the packages to Jessie (not Jessie-backports
since this leaded to strange dependency issues). As probably expected
by you this ended up in

but this somehow comes "expected" in contrast to the unmet dependencies
in the unstable chroot.
Any hint would be welcome (any volunteer for
libghc-hierarchical-clustering even more - but hints how to sensibly
start with this are welcome as well).
Kind regards
Andreas.
