To compile and install Allegria under Linux, type the following commands:

tar -zxf AllegriaYYMMDD   (where YYMMDD is the version date)
cd AllegriaYYMMDD
qmake
make  (this step will take a while, and may produce errors if you have not installed all the required packages)
ALLEGRIA_INSTALL_PATH="/home/your_user_name/directory_where_to_install_allegria"
export ALLEGRIA_INSTALL_PATH


Then, to run Allegria, type:

cd $ALLEGRIA_INSTALL_PATH
./SpectrumExtractor or ./Allegria
