Библиотека loki использует по сути универсальное программирование на С ++
Я получил код там, используя Small Object распределитель памяти (Loki :: SmallObjAllocator)
Я использую Visual C ++ 2010
Я получаю эти ошибки:
> MyLoki.cpp
1>MyLoki.obj : error LNK2019: unresolved external symbol "public: void __thiscall Loki::SmallObjAllocator::Deallocate(void *,unsigned int)" (?Deallocate@SmallObjAllocator@Loki@@QAEXPAXI@Z) referenced in function _wmain

Я нашел ответ на свой первый вопрос.

ошибки нескольких
неразрешенный внешний символ
из-за SmallObj.cpp, Локи, который не был включен в проект
например, Loki :: SmallObjAllocator, Loki :: SmallObject Вот
