Geant4/PTL/Types.hh:196:84: error: macro "max" requires 2 arguments, but only 1 given

When I compile an application, I found the below error.

Geant4/PTL/Types.hh:196:84: error: macro “max” requires 2 arguments, but only 1 given
int64_t CountedObject::fmax_depth = std::numeric_limits<int64_t>::max();

Thank you!

After changing below line from

int64_t CountedObject::fmax_depth = std::numeric_limits<int64_t>::max();

to

int64_t CountedObject::fmax_depth = (std::numeric_limits<int64_t>::max)();

the error disappeared.

Which platform is this on? It’s probable that the translation unit being compiled has a redefinition of max as a macro somewhere in it or the headers it #includes.

Thank you, Ben.
I use Ubuntu.
I agree with you. Only when I use the IAEA phase space reader, this error appears. I guess max is defined as a macro somewhere in IAEA phase space reader.
Anyway, after adding () can prevent it from being seen as a macro.
