Failed compilation from RooFit since ROOTv5.28

Hello dear rooters-helpers,

I humbly request your assitance since my codes refuses to compile since I upgraded ROOT to 5.28
My interest lies in the use of RooFit and RootStat (which were working in the previous version.)

Linked librairies contain : -lRooFit -lRooFitCore -lMinuit -lFoam

And here are the error messages :
/root/lib/libRooFit.so: undefined reference to ROOT::Math::assoc_legendre(unsigned int, unsigned int, double)' /root/lib/libRooFit.so: undefined reference toROOT::Math::noncentral_chisquared_pdf(double, double, double)’

Thank you in advance for your help.

Regards,
Philippe Velten

resolved the problem :
ROOT libs MathMore was needed…
