Erro de compilação

[SaluRamos]

estou compilando assim: g++ main.cpp -o main.exe -Iinclude -Iinclude/SDL -Iinclude/SDL_image -Llib -lmingw32 -lSDL2main -lSDL2 -lSDL2_image -lSDL2_ttf

estrutura do projeto:

Windows 10, usando VS Code.

erro:

                 from main.cpp:2:

Sou novo com c++, oque estou fazendo de errado?

estava executando o arquivo exec.bat:

cls
g++ main.cpp -o main.exe -Iinclude -Iinclude/SDL -Iinclude/SDL_image -Llib -lmingw32 -lSDL2main -lSDL2 -lSDL2_image -lSDL2_ttf
main.exe
pause

executando o output manualmente foi exibido os erros:

corrigi alterando exec.bat para jogar o output para dentro de bin:

cls
g++ main.cpp -o bin/main.exe -Iinclude -Iinclude/SDL -Iinclude/SDL_image -Llib -lmingw32 -lSDL2main -lSDL2 -lSDL2_image -lSDL2_ttf
cd bin
main.exe
pause

Parece que a lib só mostrou warnings mesmo, meu erro.
