Problem in configuring pythia8 with root and fastjet

Missing Canvas

Honestly speaking, sooner or later, you will learn by hard that the policy of using a “system-provided” ROOT version (e.g. in “/usr/[bin|lib]” or “/usr/local/[bin|lib]”) is a dead end. You will learn that you need something like three different versions of ROOT - just because something that works with a particular ROOT version is not working with another ones, or because some piece of your additional, experiment / analysis specific, software explicitly requires a particular ROOT version. The s…

Installation problems (Ubuntu 14.04)

I was trying to install root (version 5.34.23) on my computer when this error occurred: g++ -shared -Wl,-soname,libGX11TTF.so -m64 -O2 -Wl,--no-undefined -Wl,--as-needed -o lib/libGX11TTF.so graf2d/x11ttf/src/TGX11TTF.o graf2d/x11ttf/src/G__X11TTF.o -L/usr/lib/x86_64-linux-gnu -lfreetype -lz -lpng12 -Llib -lGX11 -lGraf -lXpm -lXext -lX11 -lXft -Llib -lCore -lCint -ldl graf2d/x11ttf/src/TGX11TTF.o:(.data.rel.ro._ZTV8TGX11TTF[_ZTV8TGX11TTF]+0x310): undefined reference to `TVirtualX::GetFontAscent…

Installing Root on ubuntu 14.04

Try in [t]csh (build it in “/tmp/ROOT/root”, install it into “/usr/physics/root_v5.34.32”) … cd /tmp sudo rm -rf ROOT mkdir ROOT cd ROOT wget ftp://root.cern.ch/root/root_v5.34.32.source.tar.gz tar -zxf root_v5.34.32.source.tar.gz cd root setenv ROOTSYS /usr/physics/root_v5.34.32 sudo rm -rf ${ROOTSYS} ./configure --enable-soversion --all make sudo ROOTSYS=${ROOTSYS} make install cd /tmp rm -rf ROOT If you have “libpythia8-dev” package installed, add “–with-pythia8-incdir=/usr/include/Pythia8” t…

Problem with png of divided canvas in 5-34/19 on Mac

Try the following procedure (in case anything goes wrong you’ll have additional “configure.out.txt” and “make.out.txt” files to look into): [code]# make sure we have a clean source code cd /srv/opt/root rm -f root rm -rf root_v5.34.20 wget ftp://root.cern.ch/root/root_v5.34.20.source.tar.gz tar -zxf root_v5.34.20.source.tar.gz mv root root_v5.34.20 make sure really NOTHING in the environment points to ANY old ROOT version cd /srv/opt/root rm -f root unset ROOTSYS if [ -e “${HOME}/.r…

Trouble Installing

The easiest way would be to build ROOT “in-place” (in case anything goes wrong you’ll have additional “configure.out.txt” and “make.out.txt” files to look into): rm -rf v5-34-00-patches git clone -b v5-34-00-patches http://root.cern.ch/git/root.git v5-34-00-patches cd v5-34-00-patches unset ROOTSYS ./configure --enable-soversion --all > configure.out.txt 2>&1 make > make.out.txt 2>&1 On some newer operating systems, you may need to add “--enable-gsl-shared --disable-fitsio” into the “co…
