我有一个编译新项目的问题。
编译器输出:
1>------ Build started: Project: IRPCore, Configuration: Debug Win32 ------

这里是core.cpp文件
#include <iostream>
#include <unordered_map>
#include "core.h"
core::core(void)
{
}
core::~core(void)
{
}
void core::Item_Insert(int uid, item Item)
{
core::itemCache.insert(std::make_pair<int,item>(uid, Item));
return;
}
std::string core::convertNativeStringToString(AMX *amx, cell input)
{
char *string = NULL;
amx_StrParam(amx, input, string);
return string ? string : "";
}
我需要链接更多的库或其他内容吗?
提前感谢。
编辑:以下是从core.h中获取的核心定义。
class core
{
public:
static std::unordered_map<int, item> itemCache;
core(void);
~core(void);
static void Item_Insert(int uid, item Item);
static std::string convertNativeStringToString(AMX *amx, cell input);
private:
};
core::itemCache
的静态数据成员未定义。 - Pete Becker
