Hi there, thanks to all replies.
1) What is "type", it's not declared anywhere in the snippet above.
Sorry, my mistake. Type is uint32_t.
2) I notice you saying that you're getting linker errors - that should only happen if you're taking the address of the constants somewhere - if that's a use case that you want to support, then you need a definition for the constants somewhere - suitably guarded by the right Boost.Config macros (sorry can't remember what off the top of my head).
I'm getting a compiler error with gcc 3.4.5. The compiler that comes with MinGW.
And finally, given that your constants look like enumerated values, is there actually a pressing need not to make them an anonymous enumerated type in this case?
I know about using enums for such a case. But it used to be a matter of taste since MS compiler works just fine. Seems like now it's a necessity to use enum. I was wondering how other boost libs do it? Regards, Christian
