## 3. Install and build Open MPI -- ***optional***
Download the latest version of [Open MPI][OMPI] version 3.1 (I used 3.1.5) and build it like so:
[OMPI]: https://www.open-mpi.org/software/ompi/v3.1/
../configure CC=clang CXX=clang++ CXXFLAGS=-g --prefix=$GridPre/bin
make -j 4 all install
***Note the `/bin` at the end of the prefix - this is required. As a quirk of the OpenMPI installer, `--prefix` must point to the `bin` subdirectory, with other files installed in `$GridPre/include`, `$GridPre/lib`, `$GridPre/share`, etc.***
Grid does not have any dependencies on fortran, however many standard scientific packages do, so you may wish to download GNU fortran (e.g. MacPorts ``gfortran`` package) and add the following to your configure invocation:
F77=gfortran FC=gfortran
## 4. Install and build Grid pre-requisites
## 3. Install and build Grid pre-requisites
To simplify the installation of **Grid pre-requisites**, you can use your favourite package manager, e.g.:
### 1. [MacPorts][MacPorts]
### 3.1. [MacPorts][MacPorts]
[MacPorts]: https://www.macports.org "MacPorts package manager"
Install [MacPorts][MacPorts] if you haven't done so already, and then install packages with:
sudo port install <portname>
sudo port install openmpi git-flow-avh gmp hdf5 mpfr fftw-3-single lapack wget autoconf automake bison cmake gawk libomp
These are the `portname`s for mandatory Grid libraries:
On a Mac without GPUs:
* git-flow-avh
* gmp
* hdf5
* mpfr
sudo port install OpenBLAS +native
and these are the `portname`s for optional Grid libraries:
To use `Gnu sha256sum`:
* fftw-3-single
* lapack
* doxygen
* OpenBLAS
pushd /opt/local/bin; sudo ln -s gsha256sum sha256sum; popd
***Please update this list with any packages I've missed! ... and double-check whether OpenBLAS is really for Grid. NB: lapack doesn't seem to work. Should it be scalapack?***
These `port`s are not strictly necessary, but they are helpful:
### 2. [Homebrew][Homebrew]
sudo port install gnuplot gsl h5utils nasm rclone texinfo tree xorg-server
[Homebrew]: https://brew.sh "Homebrew package manager"
***Please update this list with any packages I've missed!***
Install [Homebrew][Homebrew] if you haven't done so already, and then install packages with:
sudo brew install <packagename>
The same packages are available as from MacPorts.
### Install LIME ***optional***

### 5.2 Configure Grid
### 4.2 Configure Grid
The Xcode build system supports multiple configurations for each project, by default: `Debug` and `Release`, but more configurations can be defined. We will create separate Grid build directories for each configuration, using the Grid **Autoconf** build system to make each configuration. NB: it is **not** necessary to run `make install` on them once they are built (IDE features such as *jump to definition* will work better of you don't).
