These programs are supplied as part of most Linux distributions, so
usually they can be installed via the standard package manager. Also
distributions need to apply the patches on their own.
Ganeti will use the option if it's detected by the ``configure``
- script; auto-detection can be disabled by explicitely passing

``--enable-socat-compress`` (use the option to disable compression) or
``--disable-socat-compress`` (don't use the option).
Haskell requirements
~~~~~~~~~~~~~~~~~~~~
-If you want to enable the `htools` component, which is recommended on
-bigger deployments (this give you automatic instance placement, cluster
-balancing, etc.), then you need to have a Haskell compiler installed on
-your build machine (but this is not required on the machines which are
-just going to run Ganeti). More specifically:
+Starting with Ganeti 2.7, the Haskell GHC compiler and a few base
+libraries are required in order to build Ganeti (but not to run and
+deploy Ganeti on production machines). More specifically:
- `GHC <http://www.haskell.org/ghc/>`_ version 6.12 or higher
- or even better, `The Haskell Platform
network library
- `parallel <http://hackage.haskell.org/package/parallel>`_, a parallel
programming library (note: tested with up to version 3.x)
-- `curl <http://hackage.haskell.org/package/curl>`_, bindings for the
- curl library, only needed if you want these tools to connect to remote
- clusters (as opposed to the local one)
+- `bytestring <http://hackage.haskell.org/package/bytestring>`_ and
+ `utf8-string <http://hackage.haskell.org/package/utf8-string>`_
+ libraries; these usually come with the GHC compiler
+- `deepseq <http://hackage.haskell.org/package/deepseq>`_

- $ yum install ghc ghc-json-devel ghc-network-devel ghc-parallel-devel
-
-The most recent Fedora doesn't provide ``ghc-curl``. So this needs to be
-installed using ``cabal`` or alternatively htools can be build without
-curl support.

-were renamed::
+In Fedora, they are available via packages as well::

If using a distribution which does not provide them, first install
-the Haskell platform. You can also install ``cabal`` manualy::
+the Haskell platform. You can also install ``cabal`` manually::
$ apt-get install cabal-install
Then install the additional libraries via
``cabal``::
- $ cabal install json network parallel curl
+ $ cabal install json network parallel utf8-string
The compilation of the htools components is automatically enabled when
the compiler and the requisite libraries are found. You can use the
``--enable-htools`` configure flag to force the selection (at which
point ``./configure`` will fail if it doesn't find the prerequisites).
-In Ganeti version 2.6, one of the daemons (``ganeti-confd``) is shipped
-in two versions: the Python default version (which has no extra
-dependencies), and an experimental Haskell version. This latter version
-can be enabled via the ``./configure`` flag ``--enable-confd=haskell``
-and a few has extra dependencies:
+Haskell optional features
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Optionally, more functionality can be enabled if your build machine has
+a few more Haskell libraries enabled: RAPI access to remote cluster from
+htools (``--enable-htools-rapi``), the ``ganeti-confd``
+daemon (``--enable-confd``) and the monitoring agent
+(``--enable-monitoring``). The list of extra dependencies for these is:
+
+- `curl <http://hackage.haskell.org/package/curl>`_, tested with
+ versions 1.3.4 and above
- `hslogger <http://software.complete.org/hslogger>`_, version 1.1 and
above (note that Debian Squeeze only has version 1.0.9)
- `Crypto <http://hackage.haskell.org/package/Crypto>`_, tested with
version 4.2.4
