Error "Could NOT find PythonLibs" when building Root

Question

I got this message when I tried to install the Root software onto Ubuntu Linux. Please give me advice. What is the problem and how can I manage this?

Answer 1

(Essentially an update to squareskittles answer)

The official list of prerequisits is hosted by the root team here . For Ubuntu they list

Required packages:

 sudo apt-get install git dpkg-dev cmake g++ gcc binutils libx11-dev \\ libxpm-dev libxft-dev libxext-dev

Optional packages:

 sudo apt-get install gfortran libssl-dev libpcre3-dev \\ xlibmesa-glu-dev libglew1.5-dev libftgl-dev libmysqlclient-dev \\ libfftw3-dev libcfitsio-dev graphviz-dev \\ libavahi-compat-libdnssd-dev libldap2-dev python-dev libxml2-dev \\ libkrb5-dev libgsl0-dev libqt4-dev

Answer 2

It looks like you are building the CERN ROOT software. The CERN ROOT software has several dependencies that are needed to enable all of its features. You can install them with this command:

sudo apt-get install gfortran libssl-dev libpcre3-dev xlibmesa-glu-dev libglew1.5-dev libftgl-dev libmysqlclient-dev libfftw3-dev graphviz-dev libavahi-compat-libdnssd-dev libldap2-dev libxml2-dev libkrb5-dev libgsl0-dev libqt4-dev

This list of dependencies was taken from the linked documentation for installing ROOT (from 2017), although there are probably more recent installation instructions more applicable to your version of ROOT.
