Hello, I am writing an Apache module in C++. I need to store the common data that all childs need to read as a portion of shared memory. Structure is kind of map of vectors, so I want to use STL map and vectors for it. I have written a shared allocator and a shared manager for the purpose, they work fine for vectors but not for maps, below is the example:

typedef vector<CustomersData, SharedAllocator<CustomersData> > CustomerVector;
 CustomerVector spData;    //this one works fine

typedef SharedAllocator< pair< const int, CustomerVector > > PairAllocator;

typedef map< int, CustomerVector, less<int>, PairAllocator > SharedMap;

SharedMap spIndex;    //this one doesn't work

I get compile time errors when I try to use the second object (spIndex), which are someting like:

../SpatialIndex.h:97: error: '((SpatialIndex*)this)->SpatialIndex::spIndex' does not have class type

It looks like the compiler cannot determine a type for SharedMap template type, which is strange in my opinion, it seems to me that all the template parameters have been specified.

Can you help?

Thanks Benvenuto
