Este erro significa referência indefinida. Ocorre quando, por exemplo, é criado o protótipo da função mas seu código não. Assim o compilador irá compilar pois você disse que a função existe. Mas quando ele vai ligar tudo ele não acha a função.
Possíveis causas:

1) Criado apenas o protótipo, faltando o código da função.
2) A função está em outro arquivo que não foi passado para o compilador.

Para resolver, ao linkar, passe na linha de comando todos os arquivos .o que fazem parte do projeto.
Outra coisa: você pode compilar e linkar na mesma linha. O comando abaixo:

gcc -o teste teste.c

vai compilar e linkar o programa teste.c
Qualquer dúvida é só perguntar!

O seu problema e a falta da biblioteca ncurses como parametro para o linker.

gcc -o teste teste.c -lcurses

Para maiores informacoes, man ncurses.
