Unable to install RooFit

[Majood]

Hi There

I’m really stuck in installing RooFit. I downloaded the ROOT v5.34 source code , created a folder in home directory as build folder and run the configure file like this:

/path_to_my_untared_source_code/configure linuxx8664gcc --enable-roofit

and went on the installation as it described here:
https://root.cern.ch/installing-root-source
root works fine but when I issue this commad (in ROOT enviroment of course) i get these errors:

oot [0] gSystem->Load("libRooFit") Error in <TUnixSystem::DynamicPathName>: libRooFit[.so | .dll | .dylib | .sl | .dl | .a] does not exist in .::/usr/lib/x86_64-linux-gnu/root5.34:/usr/lib/x86_64-linux-gnu/root5.34/cint/stl (int)(-1)

and

root [0] using namespace RooFit ;
Error: namespace RooFit is not defined (tmpfile):1:
*** Interpreter error recovered ***

I’ll be more than grateful for any kind of hints

P.S.: I’m usnig Ubuntu 14.04 64 bit

P.S.S.: there is no enviromental variable as $ROOTSYS created. when I enter

echo $ROOTSYS

I get nothing, I know it’s not related to my question directly but I thought it might be somehow related

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…

Thanks for useful hint, yes it’s quit possible, I’ve just noticed that the history of commad after last remove still exist which means that I did not remove every things.

and thanks for posting this

Installing ROOT 5 from Source

The https://root.cern.ch/build-root-old-method does NOT mention “ROOTSYS” at all. A newcomer has no chance to learn that the following sequence works (the “/Where/I/Unpacked/The/Source/Code/Of/root” subdirectory must be different from the “ROOTSYS=/Where/I/Want/To/Install/root” subdirectory): cd /Where/I/Unpacked/The/Source/Code/Of/root export ROOTSYS=/Where/I/Want/To/Install/root ./configure [<arch>] --enable-soversion --all (g)make (g)make install # may need "sudo" The “./configure --help” …

earlier.

I hope this time I make it…

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…

Thanks. however , I’m unable to express my gratiude; I learn many thing about the better way of installing ROOT and the it’s advantages.
