Cannot compile sample macros on Mac OSX 10.8

[kunks112]

Greetings,

I am new to using RooStats. When I try to run the macro in the tutorials StandardProfileLikelihoodDemo.C
I receive an error Error: cannot open file “RooWorkspace.h”

This problem occurs with ROOT install on Mac OSX 10.8
These macros work with a linux distribution (Fedora and Ubuntu)

I am following the youtube series
youtube.com/watch?v=bMPoouz2UKc
on how to use Roostats.

The ROOT I have built ROOT 3.34.11 from the repository.

What am I missing?

Thanks
MK

Thanks

Some documentation would be nice, all tutorials I found never eluded to this.

Well true, but it’s true not only for roofit/roostat, but for any other tutorial(s) which require(s) some library not enabled by default. It’s not difficult to find out though - which library to enable/build

Hello,
I am facing the same problem. When exactly should I type --enable-roofit when working in CINT?

Try:
root-config --has-roofit
and if you do not get “yes”, try:
./configure --help

[Viesturs]

typing

root-config --has-roofit

produced

no

But
./configure --help
produces
-bash: ./configure: No such file or directory

[Wile_E_Coyote]

The “configure” script is in your ROOT source code directory.

[Viesturs]

There is no configure file in directory

/opt/ROOT/v6-10-02

I have no idea where to look for it

[Wile_E_Coyote]

For ROOT 6 you should use the CMake based building method.

[Viesturs]

I think CMake based building method is the one I used to install ROOT from a tarball. Can I now add Roofit to my ROOT?

[Wile_E_Coyote]

Try cmake -Dall="ON" ... and it should find and and enable all optional components that are available on your system.

[Viesturs]

From which I directory should I run it?
I get:

/opt/ROOT/v6-10-02$ cmake -Dall="ON"
CMake Error: The source directory "/opt/ROOT/v6-10-02" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.

Building ROOT

Root-6.06.00 on Ubuntu 14.04 32 bit

I don’t have a solution, but you may try the following … recreate the “source tree” from scratch (so that no old building remnants are present) and then use a “build tree” which is separate from the “source tree” (do not build ROOT 6 “in place”) and use cmake (do not use “configure + make” for ROOT 6): cd /Where/You/Build/It unset ROOTSYS cmake -Dall="ON" -Dsoversion="ON" /Where/The/Source/Code/Is > cmake.out.txt 2>&1 cmake --build . >> cmake.out.txt

ROOT 6 Build From Source Error on Ubuntu 14.04 LTS

Try: cd ~/applications/bin/ rm -rf root_source root git clone http://root.cern.ch/git/root.git root_source mkdir root cd root unset ROOTSYS cmake -Dall="ON" -Dsoversion="ON" ../root_source >> cmake.out.txt 2>&1 cmake --build . >> cmake.out.txt 2>&1

Now, do I need to:

1. rebuild the whole ROOT
2. OR simply add roofit to the existing ROOT
   ?

[Wile_E_Coyote]

I tip on rebuilding it from scratch.

[Viesturs]

Should cmake -Dall="ON" ... be added to step 4 or 5 of Quick Start at https://root.cern.ch/building-root?
