+GF Developer's Guide: Old installation instructions with Cabal
+
+
+This page contains the old installation instructions from the [Developer's Guide ../doc/gf-developers.html].
+We recommend Stack as a primary installation method, because it's easier for a Haskell beginner, and we want to keep the main instructions short.
+But if you are an experienced Haskeller and want to keep using Cabal, here are the old instructions using ``cabal install``.
+
+Note that some of these instructions may be outdated. Other parts may still be useful.
+
+== Compilation from source with Cabal ==
+
+The build system of GF is based on //Cabal//, which is part of the
+Haskell Platform, so no extra steps are needed to install it. In the simplest
+case, all you need to do to compile and install GF, after downloading the
+source code as described above, is
+
+```
+$ cabal install
+```
+
+This will automatically download any additional Haskell libraries needed to
+build GF. If this is the first time you use Cabal, you might need to run
+``cabal update`` first, to update the list of available libraries.
+
+If you want more control, the process can also be split up into the usual
+//configure//, //build// and //install// steps.
+
+=== Configure ===
+
+During the configuration phase Cabal will check that you have all
+necessary tools and libraries needed for GF. The configuration is
+started by the command:
+
+```
+$ cabal configure
+```
+
+If you don't see any error message from the above command then you
+have everything that is needed for GF. You can also add the option
+``-v`` to see more details about the configuration.
+
+You can use ``cabal configure --help`` to get a list of configuration options.
+
+=== Build ===
+
+The build phase does two things. First it builds the GF compiler from
+the Haskell source code and after that it builds the GF Resource Grammar
+Library using the already build compiler.  The simplest command is:
+
+```
+$ cabal build
+```
+
+Again you can add the option ``-v`` if you want to see more details.
+
+==== Parallel builds ====
+
+If you have Cabal>=1.20 you can enable parallel compilation by using
+
+```
+$ cabal build -j
+```
+
+or by putting a line
+```
+jobs: $ncpus
+```
+in your ``.cabal/config`` file. Cabal
+will pass this option to GHC when building the GF compiler, if you
+have GHC>=7.8.
+
+Cabal also passes ``-j`` to GF to enable parallel compilation of the
+Resource Grammar Library. This is done unconditionally to avoid
+causing problems for developers with Cabal<1.20. You can disable this
+by editing the last few lines in ``WebSetup.hs``.
+
+=== Install ===
+
+After you have compiled GF you need to install the executable and libraries
+to make the system usable.
+
+```
+$ cabal copy
+$ cabal register
+```
+
+This command installs the GF compiler for a single user, in the standard
+place used by Cabal.
+On Linux and Mac this could be ``$HOME/.cabal/bin``.
+On Mac it could also be ``$HOME/Library/Haskell/bin``.
+On Windows this is ``C:\Program Files\Haskell\bin``.
+
+The compiled GF Resource Grammar Library will be installed
+under the same prefix, e.g. in
+``$HOME/.cabal/share/gf-3.3.3/lib`` on Linux and
+in ``C:\Program Files\Haskell\gf-3.3.3\lib`` on Windows.
+
+If you want to install in some other place then use the ``--prefix``
+option during the configuration phase.
+
+=== Clean ===
+
+Sometimes you want to clean up the compilation and start again from clean
+sources. Use the clean command for this purpose:
+
+```
+$ cabal clean
+```
+
+
+%=== SDist ===
+%
+%You can use the command:
+%
+%% This does *NOT* include everything that is needed // TH 2012-08-06
+%```
+%$ cabal sdist
+%```
+%
+%to prepare archive with all source codes needed to compile GF.
+
+=== Known problems with Cabal ===
+
+Some versions of Cabal (at least version 1.16) seem to have a bug that can
+cause the following error:
+
+```
+Configuring gf-3.x...
+setup: Distribution/Simple/PackageIndex.hs:124:8-13: Assertion failed
+```
+
+The exact cause of this problem is unclear, but it seems to happen
+during the configure phase if the same version of GF is already installed,
+so a workaround is to remove the existing installation with
+
+```
+ghc-pkg unregister gf
+```
+
+You can check with ``ghc-pkg list gf`` that it is gone.
+
+== Compilation with make ==
+
+If you feel more comfortable with Makefiles then there is a thin Makefile
+wrapper arround Cabal for you. If you just type:
+```
+$ make
+```
+the configuration phase will be run automatically if needed and after that
+the sources will be compiled.
+
+%% cabal build rgl-none does not work with recent versions of Cabal
+%If you don't want to compile the resource library
+%every time then you can use:
+%```
+%$ make gf
+%```
+
+For installation use:
+```
+$ make install
+```
+For cleaning:
+```
+$ make clean
+```
+%and to build source distribution archive run:
+%```
+%$ make sdist
+%```
+
+
+== Partial builds of RGL ==
+
+**NOTE**: The following doesn't work with recent versions of ``cabal``. //(This comment was left in 2015, so make your own conclusions.)//
+%% // TH 2015-06-22
+
+%Sometimes you just want to work on the GF compiler and don't want to
+%recompile the resource library after each change. In this case use
+%this extended command:
+
+%```
+%$ cabal build rgl-none
+%```
+
+The resource grammar library can be compiled in two modes: with present
+tense only and with all tenses. By default it is compiled with all
+tenses. If you want to use the library with only present tense you can
+compile it in this special mode with the command:
+
+```
+$ cabal build present
+```
+
+You could also control which languages you want to be recompiled by
+adding the option ``langs=list``. For example the following command
+will compile only the English and the Swedish language:
+
+```
+$ cabal build langs=Eng,Swe
+```
