Manual for installing Demeter in Ubuntu 20.04

Demeter is a package to process and analyze X-ray absorption spectroscopy (XAS). Demeter

This manual is a modification of David Hughes' guide. Installation of Demeter in Ubuntu 12.04

I had to make modifications since the ifeffit was removed from Ubuntu 20.04 repository, and some of the packages were updated.

Installation of apt packages (installation of dependencies)

sudo apt-get install build-essential git gfortran gnuplot liblocal-lib-perl libx11-dev libncurses5-dev libpng-dev libwxgtk3.0-gtk3-dev libmodule-build-perl libwx-perl xauth xterm pgplot5

Making work directory

mkdir ~/work

Changing to local environment (to prevent using root privilege)

mkdir ~/local
echo 'eval $(perl -I$HOME/perl5/lib/perl5 -Mlocal::lib)' >> ~/.bashrc
echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrc
source ~/.bashrc

Setting Environment Variables

export PREFIX=$HOME/local
export WORK_DIR=~/work

Installation of ifeffit

cd $WORK_DIR
git clone https://github.com/newville/ifeffit
cd ifeffit
./configure --prefix=$PREFIX
sed -i -e 's/TERMCAP_LIB =.*/TERMCAP_LIB =-L\/usr\/lib\/x86_64-linux-gnu\/ -lncurses/g' src/cmdline/Makefile
make
make install

cd $WORK_DIR/ifeffit/wrappers/perl
cp $PREFIX/share/ifeffit/config/Makefile.PL .
perl Makefile.PL ; make ; make install

Installation of Demeter(dependencies)

cpan

(Enter yes for auto-configuration. Type in below in the cpan window. Then press Ctrl+D)

cpan[1]> o conf build_requires_install_policy yes
cpan[2]> o conf prerequisites_policy follow
cpan[3]> o conf commit

cd $WORK_DIR
git clone https://github.com/bruceravel/demeter.git
cd demeter

export PERL5LIB=$WORK_DIR/demeter:$PERL5LIB
perl ./Build.PL
#This will show the dependencies missing

./Build installdeps

(Enter y for all the packages)

There will be a error installing mod_perl during the installation of demeter. You can quit by Crtl+C if there is some error installing libperl.

Can't stat `../apache_x.x/src'
Please tell me where I can find your apache src
 [../apache_x.x/src] ../apache_x.x/src

If there is dependencies missing, try installing again. The installation will resume by the same command.

./Build installdeps

Make sure to check the dependencies.

perl ./Build.PL

Installation of Demeter

sed -i 's/croak(_swigerr)/croak("%s", _swigerr)/g' src/ifeffit_wrap.c

./Build
./Build test
./Build install

Now it should be installed and ready to be used.

X11 over SSH is slow for these app. I would suggest using xrdp or other protocols.

Updating Demeter

export WORK_DIR=~/work
export PERL5LIB=$WORK_DIR/demeter:$PERL5LIB
cd demeter
git pull

perl Build.PL

./Build installdeps
./Build
./Build test
./Build install
