Hi all,

I've recently downloaded boost to run on an IBM mainfram z/OS system (a port of vacpp). I'm trying to compile multi_index\example\hashed. cpp (which I called stuff.cpp) and I'm getting the following errors. I'm a relative newbie with C++ so I'm completely bamboozled by the compiler errors. Help with this will be greatly appreciated as I am currently in the process of trying to convince management to switch to C++ from C, and boost is one of my big hitting selling points.

"'DOC.USER.CPP(STUFF)'", line 47.60: CCN6281 (W) "offsetof" cannot be applied to "struct word_counter_entry". It is not a POD (plain old data) type.

This warning is harmless, check http://tinyurl.com/e44yv for info on how to supress it.

I think this problem is due to a difference in the version number in the __IBMCPP__ macro. Although the z/OS compiler is ported from VACPP the __IBMCPP__ macro has a different version number.

...

From the z/OS 1.6 programming reference:

__IBMCPP__ C ++ Only.

This macro indicates the version number of the z/OS C++ compiler. The format of the version number that is provided by the macro is integer PVRRM, where : P Represents the compiler product v 0 for C/370 v 1 for AD/Cycle C/370 and C/C++ for MVS/ESA v 2 for OS/390 C/C++ and 4 for z/OS C/C++ v 4 for z/OS C/C++ Release 2 and laterV Represents the version number RR Represents the release number M Represents the modification numberIn z/OS C/C++ Version 1 Release 6, the value of the macro is 41060.

I also think your problems must be somehow related to __IBMCPP__. What is the value then of __IBMCPP__ on your platform? boost/config/compiler/vacpp.h triggers an error if __IBMCPP__ > 600, so I guess your value's lower than that. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
