[Python 3.7.1] Unresolved external symbol

[FreeWar_official 18]

Hello everyone! I'm working on source to change the python lib from 2.2 to 3.7.1!
Now i have changed every single deprecated function and checked if the function return the same result and until now everything is ok!

Now i can't understand why visual studio give me the external symbol error. This is 1 of 40 errors:

GameLib.lib(MapOutdoor.obj) : error LNK2001: unresolved external symbol "public: void __thiscall CScreenFilter::SetBlendType(char,char)" (?SetBlendType@CScreenFilter@@QAEXDD@Z)

 

and this is where the function is called

m_ScreenFilter.SetBlendType((char)mc_pEnvironmentData->byFilteringAlphaSrc, (char)mc_pEnvironmentData->byFilteringAlphaDest);

 

anyone have idea about this problem?

Wrong declaration in header file!
