Unresolved external symbol on using function from library

Question

i have write small noobie library. All functions working good except templated function.

There is my code, when i use this code without library build & work success but when used with library giving unresolved external error.

Project & Library settings

-c++ language standart : latest -multibyte charset -no sdl -MT static -no optimization

       template<typename T>
       BOOL XMCore::XMHacking::WriteMemory(uintptr_t Address, T Value, bool 
       Check, HANDLE Process)
       {
            SIZE_T mWriten;
            if (Check && IsBadWritePtr((PFunc)Address, sizeof(T)))
                 return FALSE;
            if (Process == NULL)
                 *(T*)Address = Value;
            else
                 WriteProcessMemory(Process, (PFunc)Address, &Value, sizeof(T), &mWriten);
            if (Process != NULL && mWriten == 0)
                 return FALSE;
            return TRUE;
       }

Template functions need to be defined in a header file so that the code is available. — Hitobat, May 20 '18 at 20:50
`template static BOOL WriteMemory(uintptr_t Address, T Value, bool Check = false, HANDLE Process = NULL);` i dont writed here, already defined in header file — RequireBool, May 20 '18 at 20:52
The whole code of the function you pasted above must be in the header file. — Hitobat, May 20 '18 at 20:53

Template functions need to be defined in your header file to link properly.
