Error: Cannot open file "TUnuran.h"

ROOT
1

Hi,

I’m trying to run macros from TUnuran tutorial folder, but I have the following message:

Error: Cannot open file “TUnuran.h”

It’s strange. since I’ve found the TUnuran.h in the root directories (v. 5-34).

Where is the problem??

Thanks
Tin

Try:
root-config --has-unuran
and if you get “no”, that means that you need to rebuild your ROOT from scratch with “–enable-unuran” (or simply “–all”).

I got “no” :frowning:

so I need to rebuild root with that option.

I remember that I’ve needed to install also patches, this could be a problem?

I’m not an expert.

Many thanks.

Try with the current “v5-34-00-patches” source code:

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
make

Can you please elaborate in this, I’m also facing a similar problem in lxplus6 cluster where I’m getting “can’t open file TMVA/DataLoader.h”?

Hi,

Please open a new question instead of reviving old threads :slight_smile:

In that new post, please include environment, ROOT/TMVA version information, a description of what it is you want to do, and what error you encounter. This will help you get good assistance quickly!

Cheers,
Kim
