[FUG-BR] Problemas de compilação

[Carlos E. G. Carvalho]

Pessoal,

estou tentando atualizar o port libpano12, pré-requisito para atualizar
outro port, o hugin, ambos ferramentas para montar imagens panorâmicas.

Passei por alguns percalços que ajustei, mas empaquei num ponto em que
não consegui mais rastrear o erro. Abaixo a saída obtida na compilação.
Originalmente esta linha do gcc não continha o "-L../.libs" e dava outro
erro, não encontrando a libpano12.so, então compilei adicionando este -L
e entrou nessa função "_start" com "undefined reference to `main'".
Alguma dica ó gurus do C?
