ブーストマップ内のブーストマップを共有メモリに挿入する

Question

これは私がこれまで行ってきたことです。しかし、これはコンパイルさえしません。私はそれを動作させるために何をすべきですか？

typedef allocator<int, managed_shared_memory::segment_manager> vecAllocator; 
typedef vector<int, vecAllocator> vec; 
typedef std::pair<const int, vec> ValueType; 
typedef allocator<ValueType, managed_shared_memory::segment_manager> ShmemAllocator; 
typedef multimap<int, vec, std::less<int>, ShmemAllocator> MyMap; 

ShmemAllocator alloc_inst (segment.get_segment_manager()); 
vecAllocator vectorallocator (segment.get_segment_manager()); 

MyMap *mymap = segment.construct<MyMap>("MyMap")(std::less<int>(),alloc_inst); 
vec *myvec = segment.construct<vec>("myvec")(std::less<int>(), vectorallocator); 
myvec->push_back(10); 

このベクターをマップに挿入するにはどうすればよいですか？ これは私が

mymap->insert(std::pair<const int, vec>(i, myvec)); 

を試みたが、動作しているように見えるdoes notのものの一つです。私は共有メモリ内のベクトルへのポインタを作成することは正しい方法ではないことを知っています。私はマップに挿入する場合は、オブジェクトを作成する必要があります。共有メモリーにこれらのものを組み込む方法や、それをどうやって行うのですか？

ライン54は

線46はmymap->インサートラインである（戻り）主に戻り、最後の行です。

Answer 1

問題はここにある：

vec *myvec = segment.construct<vec>("myvec")(std::less<int>(), vectorallocator);

std::less<int>インスタンスを渡すための使用はありません。これを試してみてください：

vec *myvec = segment.construct<vec>("myvec")(vectorallocator);
