Hello all,

I've been trying to create an initiliser for the following (paraphrased)

struct data { Char *str;

const char*?

Typo when copying from Linux box to email box - soz!

...

Vector<int> stuff; };

map mapstuff = map_list_of (1, ("hello", list_of (3) (4) (2)), (3, ("goodbye", list_of (1) (3) );

Etc etc

However, this doesn't work, with a very complex compile error from assign. I've tried also...

map mapstuff = map_list_of (1, {"hello", list_of (3) (4) (2) } ), // note curly braces (3, {"goodbye", list_of (1) (3) ) } );

But that doesn't work either.

Is it actually possible to do something like this, and if so, how?

I suspect that you have to provide a constructor for your data class:

template< class Range > data( const char* str, const Range& r ) : str(str), stuff(boost::begin(r),boost::end(r)) { }

I did something along these lines but still got a load of compile faults. Will post a more accurate code snippet when time allows, but have a deadline end of today!!
