Installation

AZURE2 requires several external packages. The program is built using the CMake toolkit and the graphical interface is written using the Qt framework.

Dependencies

Required:

CMake 2.8 or later – build system (https://cmake.org)
GNU Scientific Library (GSL) – mathematical functions (https://www.gnu.org/software/gsl/)
Minuit2 – minimization routines, distributed within ROOT (https://root.cern.ch)
OpenMP – parallel processing support

Optional:

Qt5 – graphical user interface framework
QWT – plotting library for the built-in Plot tab (libqwt-qt5-dev, libqt5svg5-dev)
Readline – enhanced command-line input

Building from Source

Unpack the AZURE2 archive in your directory of choice:
```
tar zxvf azure2_v1.tar.gz
```
Create a build directory:
```
cd AZURE2
mkdir build
cd build
```
Run CMake to generate the Makefile:
```
cmake ..
```
Build and install:
```
make && make install
```

CMake Options

The following options can be passed to CMake using -D[OPTION]=[VALUE]:

Option	Default	Description
`BUILD_GUI`	ON	Build the graphical setup utility (recommended)
`USE_QWT`	OFF	Enable built-in plotting tab (requires QWT libraries)
`USE_STAT`	ON	Use `stat()` function for directory checking (disable for Windows)
`USE_READLINE`	ON	Enable readline library for CLI input
`BUILD_LIBRARY`	OFF	Build as a library instead of an executable
`CODE_COVERAGE`	ON	Enable coverage reporting
`MINUIT_PATH`	(auto)	Custom path for Minuit2 libraries
`GSL_PATH`	(auto)	Custom path for GSL libraries

Example with QWT plotting enabled:

cmake .. -DUSE_QWT=ON

Docker

AZURE2 supports Docker containerization for easy deployment:

# Build Docker container
source scripts/build.sh

# Run GUI container
source scripts/run_gui.sh

For HPC environments, the Docker image can be converted to Singularity/Apptainer:

sudo apptainer build AZURE2.sif docker-daemon://azure2:latest
