Note

To guarantee reproducibility in scientific calculations we strongly recommend the use of a stable release of both TRIQS and its applications.

Prerequisites

For using this package, you need the TRIQS toolbox. In the following, we will suppose that it is installed in the path_to_triqs directory. The code is compatible with TRIQS versions 3.2.

Installation steps

Download the source code of the latest stable version by cloning the TRIQS/maxent repository from GitHub:
```
$ git clone https://github.com/TRIQS/maxent maxent.src

Create and move to a new directory where you will compile the code:
```
$ mkdir maxent.build && cd maxent.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 ../maxent.src
```
Compile the code, run the tests and install the application:
```
$ make
$ make test
$ make install
```
