Re: [Boost-users] static maps (was trouble with boost::assign)

I intended for the map to stay completely static, that is, no inserts or
deletes were going to be performed.  I was going to use it for barcode
key/value pairs (as in a 0 in Code 39 has the hex code 0x51DD), since there
isn't really an easy way to figure out what goes where.  Since I couldn't
figure this out, I had to opt for a static array and an enumeration of the
names in the proper order.  Kind of a crock, but you do what you can, I
suppose.

        Hi, I'm trying initialize a static map with map_list_of. Something
along the
        lines of:
        
        map<int,int> blarg = map_list_of(1, 2); 
        
        However, when I go to compile, I receive the following error:

Can't help you with the error, unfortunately, but just wondering - does this
map *remain* static after initialization?  ie Do you do any inserts or
deletes after init?  I wrote a static_map<K, T> that is constructed from a
static array, which I use for those cases where the map doesn't change, and
I was just wondering how useful people thought it might be - ie how often do
you have maps that never change after initialization from static data?
