Hi,

    Below is my installing the ROOT v28,
(1) tar xvf root_v5.28.00.source.tar.gz
(2) cd root
(3) ./configure --enable-roofit
(4) make -j2

It is successfully compiled, and also I can run root like root -v.

The problem is the package histfactory/ under Roofit is not compiled. So we can try to histfactory, I get the error:

Warning in <TClass::TClass>: no dictionary for class

RooStats::HistFactory::LinInterpVar is available
Error in <TBufferFile::ReadObject>: trying to read an emulated class

(RooStats::HistFactory::LinInterpVar) to store in a compiled pointer
(TObject)

Error in <TClass::New with placement>: cannot create object of class RooAbsReal version 2 at address 0x1ae4b6a0

• Break *** segmentation violation

How can I compile histfactory manually? or why the package of histfactory is not compiles? Thanks.

Best,
