# CamFort

## Installation & Building

### Using Stack

We recommend using Stack (http://www.haskellstack.org) to build Camfort. 

 1. Install Stack following the instructions here: http://docs.haskellstack.org/en/stable/README/#how-to-install
 2. Checkout the latest version of language-fortran
 3. Checkout the latest version of camfort
 4. Build using Stack

```
git clone git@github.com:dorchard/language-fortran.git
git clone git@github.com:dorchard/camfort.git
cd camfort
stack build
stack install      # install binary
stack exec camfort # run camfort
```

Please note that at this time we have been unable to compile Camfort on Windows due to a problem with the hmatrix dependency. 

### Using Cabal

Cabal does not automatically install the build tools. If you wonder why
checkout haskell/cabal#220.

```
$ cabal install alex happy
```

Install the native packages needed for `hmatrix` dependency

```
sudo apt-get install libgsl0-dev liblapack-dev libatlas-base-dev
```

### For general usage

```
$ cabal install camfort
```

### For development

```
$ cabal sandbox init
$ cabal install --only-dependencies
$ cabal exec bash
```

This spawns a new shell with only the packages within the sandbox available.

```
$ ghc Main.hs -o camfort
```

This generates a camfort executable in the root directory using only the
packages in the sandbox and none of ~/.cabal or system Haskell packages.
