Missing RooFit::bindFunction definition

sinaotl · January 31, 2019, 12:37am

_ROOT Version:6.16
_Platform:CentOS 7
_Compiler:gcc 8.2

Hello everyone. I’m using roofit in pyroot. I had a code which was working some time ago but when I changed my operating system and root version, it’s not working anymore. It’s working on my laptop where I’m using Ubuntu. I know where the problem is coming from but don’t know how to solve it.

    x    = RooRealVar("x","m_{tt} [GeV]",700,6000);
    fa1 = TF1("fa1","-x",700,6000);
    rfa1 = RooFit.bindFunction(fa1,x);

Other things from RooFit work properly but it cannot bind a TF1 to a RooAbsReal

This is the error:

IncrementalExecutor::executeFunction: symbol '_ZN6RooFit12bindFunctionEP3TF1R10RooAbsReal' unresolved while linking symbol '__cf_21'!
You are probably missing the definition of RooFit::bindFunction(TF1*, RooAbsReal&)
Maybe you need to load the corresponding shared library?

      new (ret) (RooAbsReal*) (((RooAbsReal* (&)(TF1*, RooAbsReal&))RooFit::bindFunction)(*(TF1**)args[0], (RooAbsReal&)*(RooAbsReal*)args[1]));
      return;
   }
   else {
      ((RooAbsReal* (&)(TF1*, RooAbsReal&))RooFit::bindFunction)(*(TF1**)args[0], (RooAbsReal&)*(RooAbsReal*)args[1]);
      return;
   }
}

Hi,

Your example its working on my ROOT build. Are you sure you have built all the RooFit libraries, libRooFit and libRooFitCore ?

Lorenzo

sinaotl · February 1, 2019, 5:50pm

Hi Lorenzo.
This is working on my other system as well but I don’t know what I’m missing in the build that it’s not working right now. How should I install those libraries?
This is how I build my ROOT:
cmake … -Dall=ON

Thanks.

moneta · February 1, 2019, 7:44pm

Ho

-Dall=In should be enough.

Then I would need to try on a similar machine. Can you remember me the architecture and compiler version?

Lorenzo

sinaotl · February 1, 2019, 7:52pm

Hi,

CentOS-7-x86_64-Everything-1809-01
GCC version = 8.2.0
cmake version = 3.13.3

Do you need any other information?

sinaotl · February 3, 2019, 5:39am

I even tried ROOT version 5.99.06 and I get the similiar error:

IncrementalExecutor: use of undefined symbol '_ZN6RooFit12bindFunctionEP3TF1R10RooAbsReal'!
IncrementalExecutor: calling unresolved symbol, see previous error message!

Hi,
I have tested on yhour arch and compiler, (cerntos7 + gcc 8.2) and your 3 lines :

    x    = RooRealVar("x","m_{tt} [GeV]",700,6000)
    fa1 = TF1("fa1","-x",700,6000)
    rfa1 = RooFit.bindFunction(fa1,x)

works fine.

Maybe you are having some configuration errors in your ROOT build. How did you install ROOT, from binaries or did you build it from source ?

Lorenzo

sinaotl · February 4, 2019, 8:08pm

Hi Lorenzo,
I built it from the source file.

moneta · February 5, 2019, 2:46pm

I don’t know then what could cause your problem. Have you tried in C++ if it works ? If not it might be a PyROOT problem

Lorenzo

sinaotl · February 5, 2019, 7:57pm

Yes I had tried it.
It gives the same error with C++!!

Hi,

Can you send the output of

ls -l /home/sina/Apps/root/lib/libRooFit*.so

Axel.

Axel · February 6, 2019, 7:51pm

The issue is likely due to RooFit::bindFunction being in libRooFit, while the other symbols you use are in libRooFitCore. ROOT fails to automatically load libRooFit, because autoloading based on functions doesn’t work yet - we’re working on this, though!

If you add gSystem.Load("libRooFit") before the use of RooFit.bindFunction things should look better. Can you confirm?

sinaotl · February 6, 2019, 8:24pm

Oh my!!
Thank you very much indeed Axel. It worked!
