Prerequisites:<\/p>\n

sudo apt install build-essential git subversion dpkg-dev make g++ gcc binutils libx11-dev libxpm-dev libxft-dev libxext-dev<\/code><\/p>\n

Optional (recommended) prerequisites:<\/p>\n

sudo apt install gfortran libssl-dev libpcre3-dev libglu1-mesa-dev libglew-dev libftgl-dev libmysqlclient-dev libfftw3-dev libcfitsio3-dev graphviz-dev libavahi-compat-libdnssd-dev libldap2-dev python-dev libxml2-dev libkrb5-dev libgsl0-dev libqt4-dev<\/code><\/p>\n

Optionally, install GSL<\/a> and CASTOR<\/a> libraries, and Geant4 prerequisites<\/a>.<\/p>\n

Install font server and fonts for ROOT:<\/p>\n

sudo apt install xfstt<\/code>
\nsudo apt install t1-xfree86-nonfree ttf-xfree86-nonfree ttf-xfree86-nonfree-syriac xfonts-75dpi xfonts-100dpi<\/code>
\nservice xfstt start<\/code><\/p>\n

(Source: http:\/\/root.cern.ch\/phpBB3\/viewtopic.php?f=3&t=12627<\/a>)<\/p>\n

Update: cmake-based build<\/h5>\n

Get ROOT sources as in https:\/\/root.cern.ch\/get-root-sources<\/a>:<\/p>\n

mkdir ROOT && cd ROOT<\/code>
\ngit clone http:\/\/root.cern.ch\/git\/root.git<\/code>
\nmv root root-sources<\/code>
\nmkdir root-build<\/code>
\nmkdir root-install<\/code>
\ncd root-sources<\/code>
\ngit tag -l<\/code><\/p>\n

Choose your preferred version. As an example, v6-14-04:<\/p>\n

git checkout -b v6-14-04 v6-14-04<\/code><\/p>\n

Now build ROOT (ref. https:\/\/root.cern.ch\/building-root<\/a>):<\/p>\n

cd ..\/root-build<\/code>
\ncmake -DCMAKE_INSTALL_PREFIX=$HOME\/ROOT\/root-install -DPYTHIA8_DIR=$PYTHIA8 -DPYTHIA8_INCLUDE_DIR=$PYTHIA8\/include -DPYTHIA8_LIBRARY=$PYTHIA8\/lib\/libpythia8.so -DGSL_DIR=\/usr\/local -Dbuiltin_xrootd=ON -Droofit=ON -Dpythia8=ON ..\/root-sources<\/code><\/p>\n

or, to make it use python3 instead, assuming a new installation under ROOT\/ROOT-PY3 (source: https:\/\/root-forum.cern.ch\/t\/how-to-properly-install-pyroot-for-python-3\/26367<\/a>):<\/p>\n

cmake -DCMAKE_INSTALL_PREFIX=$HOME\/ROOT\/ROOT-PY3\/root-install -DPYTHIA8_DIR=$PYTHIA8 -DPYTHIA8_INCLUDE_DIR=$PYTHIA8\/include -DPYTHIA8_LIBRARY=$PYTHIA8\/lib\/libpythia8.so -DGSL_DIR=\/usr\/local -Dbuiltin_xrootd=ON -Droofit=ON -Dpythia8=ON -Dpython3=ON -DPYTHON_EXECUTABLE=\/usr\/bin\/python3 ..\/root-sources<\/code>
\ncmake --build . --target install -- -jN<\/code><\/p>\n

Outdated: make-based build<\/h5>\n

Get ROOT (last stable version 5.34):<\/p>\n

wget ftp:\/\/root.cern.ch\/root\/root_v5.34.14.source.tar.gz<\/code>
\ngzip -dc root_v5.34.14.source.tar.gz | tar -xf -<\/code><\/p>\n

Or get ROOT 5.99:<\/p>\n

git clone http:\/\/root.cern.ch\/git\/root.git<\/code>
\ncd root && git tag -l<\/code>
\ngit checkout -b v5-99-05 v5-99-05<\/code><\/p>\n

Compile ROOT (if you do not need GSL or Pythia, drop the configure arguments):<\/p>\n

cd root<\/code>
\n.\/configure --all --with-gsl-incdir=\"\/usr\/local\/include\" --with-gsl-libdir=\"\/usr\/local\/lib\" --enable-pythia8 --with-pythia8-incdir=$PYTHIA8\/include --with-pythia8-libdir=$PYTHIA8\/lib<\/code>
\nmake -j N<\/code><\/p>\n

where N is the number of CPU cores:<\/p>\n

cat \/proc\/cpuinfo | grep 'cpu cores'<\/code><\/p>\n

For Ubuntu 14.04 you will also need to do:<\/p>\n

sudo mkdir \/usr\/include\/freetype && sudo cp \/usr\/include\/freetype2\/freetype.h \/usr\/include\/freetype\/freetype.h<\/code><\/p>\n

Setup environment:<\/p>\n

echo \"source $PWD\/bin\/thisroot.sh\" >> $HOME\/.bashrc<\/code>
\nsource $HOME\/.bashrc<\/code><\/p>\n

Adjust the path to your needs.<\/p>\n

Installing a specific ROOT version on LxPlus \/ Fedora \/ Red Hat<\/h5>\n

The newest xrootd-devel (version 3.3) RPMs for Fedora\/RedHat\/SL do not include the XrdClient\/XrdClientConn.hh header file anymore (it was there in version 3.1). There is a transitional package xrootd-private-devel that will install the missing header files into \/usr\/include\/xrootd.<\/p><\/blockquote>\n

(From http:\/\/root.cern.ch\/phpBB3\/viewtopic.php?f=3&t=16096<\/a>.)<\/p>\n

To avoid compilation errors, do:<\/p>\n

.\/configure --with-xrootd-incdir=\"\/usr\/include\/xrootd\" --with-xrootd-incdir=\"\/usr\/include\/xrootd\"<\/code><\/p>\n

adding any other user option, for example:<\/p>\n

.\/configure --all --with-xrootd-incdir=\"\/usr\/include\/xrootd\" --with-xrootd-incdir=\"\/usr\/include\/xrootd\" --enable-pythia8 --with-pythia8-incdir=$PYTHIA8\/include --with-pythia8-libdir=$PYTHIA8\/lib <\/code><\/p>\n

To use pyroot<\/strong> there are further adjustments to do: follow the instructions on this page<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
