Do you know how to silence (or remove) this kind of warning?

Pepe_Le_Pew · February 1, 2016, 10:04am

Add to your compiler flags -Wno-shadow

pamputt · February 1, 2016, 10:08am

Actually, I would like to be able to detect the shadow in my own code so I guess I cannot use this flag. Bascially I do not know if there is something I can do from the user space. Maybe something maybe modified in the ROOT code or the GEANT4 code to suppress these warnings.

From your source code, remove all “using namespace CLHEP;” and use explicitly “CLHEP::s” where you need it.

I have no “using namespace CLHEP;” in my own code so I guess all of them come from the GEANT4 code.
If so, I do not think the GEANT4 developers would agree to force user to use “CLHEP::s” instead of only “s” because it is nowadays wiedely use in the GEANT4 simulation.
So I do not know if there is something to do within the ROOT code to avoid that.

No header file of Geant4 brings “using namespace CLHEP” nor header files from ROOT, obviously, so it is in your code that the using namespace CLHEP is declared. Please check in your .hh or .cc files.

Hi,

proj-clhep.web.cern.ch/proj-clh … ource.html shows that s is on global scope.

Yikes.

Cheers, Axel.

…to clarify: this is not a ROOT issue. This is an absurdity in CLHEP. SystemOfUnits.h should not be #include’d in any header file…

Cheers, Axel.

Pepe_Le_Pew · February 1, 2016, 5:30pm

The “SystemOfUnits.h” doxygen page that you show is completely outdated (it’s CLHEP 1.8.x.y from 2002).
Any decent version uses the CLHEP namespace.
They all contain, however:

#ifdef ENABLE_BACKWARDS_COMPATIBILITY
//  backwards compatibility will be enabled ONLY in CLHEP 1.9
using namespace CLHEP;
#endif

So, it seems that one may have problems with ROOT and CLHEP 1.9.x.y but it should work fine with CLHEP 2.0.x.y or 2.1.x.y or newer.

Hello, I am getting the same warning message (running geant version 4.10.1 and root version 5.34). Haven’t been able to fix it. Regards, Oliver

Pepe_Le_Pew · February 2, 2016, 11:28am

I have just downloaded Linux binary releases of Geant4 10.1.2 (CLHEP 2.2.0.4) and Geant4 10.2.0 (CLHEP 2.3.1.1) provided by the Geant4 team.
In both cases, “SystemOfUnits.h” contains “namespace CLHEP” (the “ENABLE_BACKWARDS_COMPATIBILITY” feature is removed completely from these new CLHEP releases) and there is NO single place which says “using namespace CLHEP;”.

pamputt · February 3, 2016, 11:03am

I am sure to understand verything from the technical part. What I can say is I do not have any “using namespace CLHEP;” in my code. I attach all my code if you want to check by yourself. To compile you have to go to Ge250/build and type “cmake …”, then “make”. And you will see all these warning messages.

PS : I am using ROOT 6.06/00 and GEANT4.10.2

The problem is that your code includes G4SystemOfUnits.hh and this is [almost] equivalent to using namespace CLHEP.
See www-zeuthen.desy.de/geant4/gean … ource.html

You could play by changing the order of file includes. For example in Ge250RunAction.cc if you invert the following two lines you could probably get away of these warnings.

#include "G4SystemOfUnits.hh"
#include "Ge250AnalysisManager.hh"

pamputt · February 3, 2016, 12:35pm

Indeed, this was the problem. Including “my” headers before the GEANT4 ones solves this “issue”. Thank you.

Shubham_Dutta · December 23, 2018, 4:29pm

The exact error is that in file SystemOfUnits.hh s is globally declared as s = seconds. On the other hand the TString.h header file of ROOT uses the same variable name s as a pointer in this line

inline TBuffer &operator>>(TBuffer &buf, Short_t &s) { buf.ReadShort(s); return buf; }

This creates a conflict and hence the error.

Please don’t resurrect a 3 year old topic, but post your question as a new topic, referencing this topic by posting its URL.

In that new topic, please copy & paste the actual warning you see. Thanks!

Cheers, Axel.
