Compiling hubbardI from source

Note

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

Prerequisites

The TRIQS library, see TRIQS installation instruction. In the following, we assume that TRIQS is installed in the directory path_to_triqs.

Installation steps

Download the source code of the latest stable version by cloning the TRIQS/hubbardI repository from GitHub:
```
$ git clone https://github.com/TRIQS/hubbardI hubbardI.src
```
Create and move to a new directory where you will compile the code:
```
$ mkdir hubbardI.build && cd hubbardI.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 ../hubbardI.src
```
Compile the code, run the tests and install the application:
```
$ make test
$ make install
```

Version compatibility

Keep in mind that the version of hubbardI must be compatible with your TRIQS library version, see TRIQS website. In particular the Major and Minor Version numbers have to be the same. To use a particular version, go into the directory with the sources, and look at all available versions:

$ cd hubbardI.src && git tag

Checkout the version of the code that you want:

$ git checkout 2.2.0

and follow steps 2 to 4 above to compile the code.

Custom CMake options

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

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