Without this patch, attempts to install at least some of the packages
that start to use setupHaskellDepends (mostly gtk-related packages)
results in collisions:
building path(s) ‘/nix/store/63k5smns43f5r2ad8wcc242x0gwd70m3-ghc-8.0.1’
collision between `/nix/store/k18i1nm5hgnb82y9w2g9hmlwhk3szjld-ghc-8.0.1/lib/ghc-8.0.1/Cabal-1.24.0.0/Distribution/Compat/Binary.dyn_hi' and `/nix/store/0rwhbwsg9kmywgbrib2bs29p2hmi80za-Cabal-1.24.0.0/lib/ghc-8.0.1/Cabal-1.24.0.0/Distribution/Compat/Binary.dyn_hi'
builder for ‘/nix/store/vrjkfpm8sb96m9i5k74h8vn0rwddgy4v-ghc-8.0.1.drv’ failed with exit code 25
This would appear to me to be a consequence of setupHaskellDepends
entries being added to propagateBuildInputs. It is sufficient in the
cases I'm familiar with (taffyBar), and I think correct, to simply add
it to the otherBuildInputs.
Previously, the user could only compile using the default version of
GHC in Nixpkgs. Now this can be changed by setting the `ghc` attribute
appropriately.
From the changelog:
```
Version 0.7.86, 2016-05-31
+ Linux/Mac: more output formats (PBCore, EBUCore, FIMS)
+ FFV1 parsing optimization, avoiding by default a too verbose trace
+ Matroska: more elements support and typo fixes in the trace
+ #I172, Trace feature: provide the name of the main parser in the media element
+ Matroska: consider all values below 0x10 EBML names as 1-byte junk
x Matroska: better support (including speed improvement) of huge lossless frames (e.g. 20 MB FFV1 4K)
x #I144, Python binding: Python 2 on Linux does not automatically provide the locale to the shared object
x HTML output: don't escape carriage returns from the input file
x FFV1: some streams were rejected despite the fact they are valid
x Python binding: some errors during call of Get() API with Python3 on Linux/Mac
```
The function "callHackage <name> <version>" generates build instructions for
the requested library version on-the-fly. All of Hackage is available. Note:
this code is brand-new, experimental, and it might change in the future. Don't
base production code on this feature yet.
Example usage:
$ nix-shell -p 'haskellPackages.callHackage "cpphs" "1.19.3" {}' --run "cpphs --version"
cpphs 1.19.3
$ nix-shell -p 'haskellPackages.ghcWithPackages (self: [(self.callHackage "hsdns" "1.6.1" {})])' --run "ghc-pkg list hsdns"
/nix/store/p6r81k2vb2pzy4wcvri6z9m492i0hg63-ghc-8.0.1/lib/ghc-8.0.1/package.conf.d
hsdns-1.6.1
