Installation

Docker

A Docker image including the latest version of SOM as well as other TRIQS applications is available here.

Compiling SOM from source

Prerequisites

The TRIQS toolbox version 3.2.x (see TRIQS installation instructions). In the following, we will assume that it is installed in the directory path_to_triqs.

Installation steps

Download the source code of the latest stable version by cloning the krivenko/som repository from GitHub:

$ git clone -b 2.1.0 https://github.com/krivenko/som.git som.src

Create and move to a new directory where you will compile the code:
```
$ mkdir som.build && cd som.build
```
Ensure that your shell contains the TRIQS environment variables by sourcing the triqsvars.sh file from your TRIQS installation:
```
$ source path_to_triqs/share/triqs/triqsvars.sh
```
In the build directory call cmake, including any additional custom CMake options, see below:
```
$ cmake ../som.src
```
Compile the code, run the unit tests and install the application:
```
$ make
$ make test
$ make install
```

Custom CMake options

The compilation of SOM can be configured using CMake-options:

cmake ../som.src -DOPTION1=value1 -DOPTION2=value2 ...
