Não é possível executar o evince. Diz biblioteca compartilhada está faltando [fechado]

Question

Ao tentar começar, o Ubuntu 12.04 me responde:

% evince
evince: error while loading shared libraries: libSM.so.6: cannot open shared object file: No such file or directory

Por outro lado, ldd não apresenta problemas.

% ldd /usr/bin/evince
    linux-vdso.so.1 =>  (0x00007fffa15ff000)
    libSM.so.6 => /usr/lib/x86_64-linux-gnu/libSM.so.6 (0x00007f57bdb04000)
    libICE.so.6 => /usr/lib/x86_64-linux-gnu/libICE.so.6 (0x00007f57bd8ea000)
    libevdocument3.so.4 => /usr/lib/libevdocument3.so.4 (0x00007f57bd6b5000)
        ...

Suponho que haja um problema ao carregar bibliotecas compartilhadas. libSM é apenas o primeiro. Pedir ao Ubuntu para ser mais detalhado não trouxe nenhuma ideia para mim.

Mas

% unset LD_DEBUG
% ls -l /usr/lib/x86_64-linux-gnu/libSM.so.6
lrwxrwxrwx 1 root root 14 lip 25  2012 /usr/lib/x86_64-linux-gnu/libSM.so.6 -> libSM.so.6.0.1
% ls -l /usr/lib/x86_64-linux-gnu/libSM.so.6.0.1 
-rw-r--r-- 1 root root 30888 mar  2  2012 /usr/lib/x86_64-linux-gnu/libSM.so.6.0.1

O problema ocorre apenas com o evince. Outros programas são executados sem falhas.

Regenerar /etc/ld.so.cache não altera nada.

% ldconfig
% ls -l /etc/ld.so.cache 
-rw-r--r-- 1 root root 84443 lis  6 17:17 /etc/ld.so.cache
% evince
evince: error while loading shared libraries: libSM.so.6: cannot open shared object file: No such file or directory

gv depende de libSM também e é executado sem problemas. Vamos comparar

Aqui loader encontra entrada em seu cache.

    

Answer 1

Podemos reproduzir esse problema em um sistema 12.04 com

/usr/lib um link simbólico (do ext4 montado / ) para /usr1/lib (ext3 montado /usr1 )

Mover /usr1/lib para /usr corrige o problema.

Acontece apenas com o evince, não com outros programas como gv que usa libSM

O pôster original também dividiu montagens / sistemas de arquivos variados?
