Hi,

I replaced [b]step-1 and 2[/b]:
[code]
export QTROOTSYSDIR=pwd/qtrootsys
export QTROOTSYSDIR=$ROOTSYS

then I proceed to the step, qmake WHICH produces the following output:

me@me/QtRoot/qtRoot$ qmake
Project MESSAGE: excluding
Project MESSAGE:  Installing <qt qtgui qtgl qtthread qtimage qtroot qt4ged> of QtRoot system
Project MESSAGE:  To remove some packages from the build, start the qmake utility as follows:
Project MESSAGE:  
Project MESSAGE:  > qmake QTPACKAGES -= <list of unwanted packages>
Project MESSAGE:  
Project MESSAGE: type <make install> - to install qt qtgui qtgl qtthread qtimage qtroot qt4ged of QtRoot into </home/me/root> directory
Project MESSAGE:

and then I ran make that failed badly ! The output is huge so I am attaching a txt file, but I am posting below the last few lines that states the exact error:

src/TQtContextMenuImp.cxx:17:22: fatal error: QWebView: No such file or directory
compilation terminated.
Makefile:1437: recipe for target '.obj/TQtContextMenuImp.o' failed
make[1]: *** [.obj/TQtContextMenuImp.o] Error 1
make[1]: Leaving directory '/home/me/QtRoot/qtRoot/qtgui'
Makefile:81: recipe for target 'sub-qtgui-make_default-ordered' failed
make: *** [sub-qtgui-make_default-ordered] Error 2

How can I make this work ?

Additional info:
1. I already had a Qt 5.7.1 (not root QT) installed on my Ubuntu 16.04 (64 bit) system.
2. My ROOT version is 5.34/36.

Complement the existent ROOT installation with QtRoot plugin(x11 only)

On X11 platforms one can complement any existent ROOT installation with the QtRoot package.
First time installation
First make sure you provide the correct ROOT and Qt environment. This means

The env variables ROOTSYS and QTDIR are defined.
$ROOTSYS/lib and $QTDIR/lib directory are present on your LD_LIBRARY_PATH
$ROOTSYS/bin and $QTDIR/bin directory are present on your PATH

Create some directory you want QtRoot to be installed in. For example "QtRoot".

 mkdir -p QtRoot/qtrootsys
 cd QtRoot
 setenv QTROOTSYSDIR `pwd`/qtrootsys # Use the dedicated directory 
                                     # to keep ROOT and QtRoot separately

 # setenv QTROOTSYSDIR $ROOTSYS      # This will merge ROOT and QtRoot 
                                     # libraries and header files

 svn co https://qtroot.svn.sourceforge.net/svnroot/qtroot/trunk  qtRoot
 cd qtRoot
 qmake
 make
 make install

If you opt for the dedicated directory for Qt Root then do not forget to include the new package into your environment

   setenv LD_LIBRARY_PATH $QTROOTSYSDIR/lib:$LD_LIBRARY_PATH

For MacOS one needs:

   export DYLD_LIBRARY_PATH=${QTROOTSYSDIR}/lib:$DYLD_LIBRARY_PATH

and customize either .roootrc or $ROOTSYS/etc/system.rootrc file to turn the Qt-layer "on"
Upgrade the existent installation
To upgrade the "complement" installation with the latest QtRoot version one has to

 cd QtRoot
 setenv QTROOTSYSDIR `pwd`/qtrootsys # Use the dedicated directory 
                                     # to keep ROOT and QtRoot separately

 # setenv QTROOTSYSDIR $ROOTSYS      # This will merge ROOT and QtRoot 
                                     # libraries and header files
 svn co https://qtroot.svn.sourceforge.net/svnroot/qtroot/trunk  qtRoot
 cd qtRoot
 qmake
 make
 make install

Test

To test your installation
Set the package environment. To do that you need to find and select one of the 3 shell scripts created by the "Full Installation"

  source set_environment.csh
  source set_environment.sh  # this script is Ok for Cygwin environment as well)
  source set_environment.tcsh

If you skipped the "Full Installation" you may want to set the environment "by hand" too. For example, set_environment.sh does

!/bin/bash

export QTDIR=my/Qt-4.5.2
export QMAKESPEC=
export QT_CONF_OPTS= -fast -opensource -opengl
export ROOTSYS=cernroot
export QTROOTSYSDIR=cernroot
export LD_LIBRARY_PATH=$ROOTSYS/lib:$QTDIR/lib:$LD_LIBRARY_PATH
export PATH=$ROOTSYS/bin:$QTDIR/bin:$PATH

For Mac OC one needs

export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:$LD_LIBRARY_PATH

as well.
Select the qtExamples directory and build the test suite:

  cd qtExamples
  qmake
  make (or "nmake" for the Visual Studio environment)
