Issue when building 'shader loader' in C++

[sone0206YA3T6]

Hello Everyone.

I'm writing a shader in C++ for the first time as a homework during winter vacation but stuck with a problem whenever I build a shader loader.
Does anyone know how to solve the Error 'unresolved external symbol "Sahder1Mtd"'?
I'm beginner in C++ as well and couldn't find any solution from internet..
Any help will be appreciated. Thanks.

Add 'const' .. extern const AtNodeMethods* mymethod

It works after adding 'const'.
Thank you very much!!
