Erro de compilação com biblioteca gnu/cgi [RESOLVIDO]

Olá, como faço para resolver esse problema: Instalei a biblioteca cgi, porém o programa não compila, mostrando essas mensagens:

Estou seguindo esse texto aqui: https://www.tutorialspoint.com/cplusplus/cpp_web_programming.htm
Mais espeficamente onde demostra o primeiro código com método get.

Eu compilei assim : g++ -o cpp_get.cgi cpp_get.cpp
O -lcgicc vem depois do g++ ?
sim, instalei a lib.

Sem problemas. só o -lcgicc funcionou. Obrigado SamL !
