Install CTSEG-J

Compiling CTSEG-J 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/ctseg_J repository from GitHub:
```
$ git clone https://github.com/TRIQS/ctseg_J ctseg.src
```
Create and move to a new directory where you will compile the code:
```
$ mkdir ctseg.build && cd ctseg.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 ../ctseg.src
```
Compile the code, run the tests and install the application:
```
$ make
$ make test
$ make install
```

Version compatibility

Keep in mind that the version of CTSEG-J 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 ctseg.src && git tag

Checkout the version of the code that you want:

$ git checkout 2.1.0

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

Custom CMake options

The compilation of CTSEG-J can be configured using CMake-options:

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

Options	Syntax
Specify an installation path other than path_to_triqs	-DCMAKE_INSTALL_PREFIX=path_to_ctseg
Build in Debugging Mode	-DCMAKE_BUILD_TYPE=Debug
Disable testing (not recommended)	-DBuild_Tests=OFF
Build the documentation	-DBuild_Documentation=ON
