CGAL e seus includes

mrpriest · 14 de agosto de 2009

Olá, pessoal!

Estou tentando executar um dos exemplos da biblioteca CGAL, mais especificamente, o exemplo do voronoi bidimensional.

Na primeira compilação, houve diversos erros, indicando a ausência de arquivos como basic.h.

Procurei pela internet esses arquivos e fui conseguindo um a um. Mas agora tive os seguintes erros:

1>c:\program files\cgal-3.4\include\cgal\boost\type_traits\is_same.hpp(36) : error C2065: 'is_same' : undeclared identifier

1>c:\program files\cgal-3.4\include\cgal\boost\type_traits\is_same.hpp(36) : error C2065: 'T' : undeclared identifier

1>Build log was saved at "file://c:\Users\mrp\Documents\Visual Studio 2008\Projects\TesteCGAL\Debug\BuildLog.htm"

1>TesteCGAL - 15 error(s), 2 warning(s)

Se alguém puder me ajudar, estou aguardando.

Obrigado!!

Você apenas baixou o gcal e tentou compilar?

Usou o CMAKE? Baixou o boost?

Eu nunca usei essa lib, mas pelo manual dela parece que é preciso seguir alguns passos antes de compilar:

Agora eu instalei a CMAKE, a BOOST e outras que vi no manual. Vou começar o teste e volto para dizer o resultado desse teste.

Agora eu tenho 150 erros, todos no arquivo is_same da boost.

Oi, pessoal!

A CGAL foi instalada, assim como o cmake, o QT, a Boost... Mas ainda não consigo compilar os exemplos em que tenho interesse, que o do Voronoi.

Compilei apenas um pequeno exemplo que mostra uma janela. O do Voronoi eu não consigo compilar.

Se alguém tiver alguma sugestão para resolver os erros a seguir, envie-me.

Obrigado!
