apt e consertando dependências do incorect

Question

Eu geralmente compilo o que eu preciso, mas estou tentando padronizar minha plataforma de desenvolvimento. Estou executando um schroot de desenvolvimento no Ubuntu (base 11.10: development 12. whatever).

Instalei o boost 1.48 e agora estou tentando instalar o mongodb-dev. Parece depender indiretamente do libboost1.46-dev via libboost-dev. Qual é a solução mais limpa e mais duradoura para eu resolver esse problema?

Estado do meu sistema:

(precise_amd64)hassan@hassan-ubuntu:~/dev/twit/scripts/bin$ sudo apt-get install mongodb-dev

Answer 1

Como você notou, o pacote (vazio) libboost-dev depende do libbost1.46-dev ao invés do libbost1.48-dev (por causa de alguns problemas com pacotes existentes ).

Para resolver isso, reconstrua-o com

apt-get source  libboost-dev # get the source files
cd boost-defaults*
sed -i -e "s/1.46/1.48/g" debian/control # replace 1.46 with 1.48
debuild -uc -us # rebuild the package
dpkg -i ../libboost*.deb # install it.

Para isso, você precisa ter o pacote devscripts instalado.

A maneira mais correta seria adicionar uma nova entrada do changelog a debian/changelog para impedir a atualização do pacote.

Como alternativa, você pode criar um pacote simulado com equivs .
