Pyroot libraries not found

Hi Sylvain,

Have you executed the "thisroot.sh" script provided with root in order to setup all environment variables in a suitable way before starting ma5?

Regards,

Benjamin

Hi Benjamin,

Thanks a loy for your quick reply.
Yes I do run "source ./bin/thisroot.sh" before starting ma5.

Cheers
Sylvain

Could you please double-check the vlaue of the ROOTSYS variable?

Hi Benjamin,

The ROOTSYS variable is empty...
So it looks like the thisroot.sh did not work for some reason...

Hi again,

So I set ROOTSYS by hand, and now my variables are somewhat defined. To be exhaustive:

$ echo $PATH
/home/sylvain/root/bin (+ others)
$ echo $LD_LIBRARY_PATH
/home/sylvain/root/lib
$ echo $DYLD_LIBRARY_PATH
/home/sylvain/root/lib
$ echo $SHLIB_PATH
/home/sylvain/root/lib
$ echo $LIBPATH
/home/sylvain/root/lib
$ echo $PYTHONPATH
/home/sylvain/root/lib
$ echo $MANPATH
/home/sylvain/root/man

Still, ma5 still does not find pyroot,
 ** ERROR: ROOT file called '/usr/lib/x86_64-linux-gnu/libPyROOT.so' is not found
 ** ERROR: Please check that ROOT is properly installed.

Any idea ?

Cheers
Sylvain

Hi again Benjamin,

The problem was simply that I was using various shells at the same time. As the variables are set within a given shell, it couldn't work.
Then I got another error:
** ERROR: 'root-config --libdir' indicates a wrong path for ROOT libraries. Please specify the ROOT library path into the environnement variable $PYTHONPATH

I didn't understand that, the paths were correct.

Anyway, I rebuilt root, and now ma5 works smoothly, including after rebooting the system.

Cheers
Sylvain

Indeed. Could you try to set it independently. I guess this would fix the problem.

Cheers,

Benjamin
