Thank you for the note! Since G4String is "just" a std::string, can you tell me if the XL compiler also complains about the following?
std::string hw("Hello, World");
std::cout << (5>3?hw:"Goodbye, World") << std::endl;
In principle, this should cause the same error which you reported. I'm curious whether XL treats "direct" STL stuff differently from subclasses.
As for the reported issue, I can fix your problem by replacing "GetName()" with "GetName().c_str()". That avoids creating temporary G4Strings, which are a non-trivial performance hit.
Hi Michael- The XL compiler was happy with that code fragment. Cheers, Tom This has finally been fixed. Unfortunately, the fix didn't get into the 10.1-beta; my apologies. |
Using the IBM XL compiler (which I know is unsupported) I get the following error in source/processes/hadronic/models/cascade/cascade/src/G4CascadeFinalStateAlgorithm.cc, lines 152 and 153: 1540-0207 (S) No common type found for operands with type "const G4String" and "const char [1]" if (GetVerboseLevel()>1) { G4cout << " " << (momDist?momDist->GetName():"") << " " << (angDist?angDist->GetName():"") << G4endl; } This appears to be because G4cout is asked to stream either a string or a G4String, and it won't know until runtime which it is. This can be fixed by forcing it to always be a G4String, i.e. if (GetVerboseLevel()>1) { G4cout << " " << (momDist?momDist->GetName():G4String("")) << " " << (angDist?angDist->GetName():G4String("")) << G4endl; } The same problem occurs in /source/processes/phonon/src/G4LatticeManager.cc in lines 200, 207, 220 and 226. The above fix compiles OK on both IBM XL and GCC.
