Hi, all:

     I am trying to install the multilib for 32 bit program to running in my arch linux. I follow the wiki, and uncomment the multilib in the /etc/pacman.conf as follows:

[multilib]
Include = /etc/pacman.d/mirrorlist

And then I run my 32 bit program, it shows:

./predict_seq_ss: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

I try run: 

#pacman -S libstdc++5

#pacman -Ql libstdc++5

I get the libstdc++.so.5 in the folder /lib, however, I don't see any folder like /lib32, and also my program still get the same error, it seems my program still don't find the libstdc++.so.5 libraries. Is there any one can give me some suggestions about what I missed to do? Thank you very much!
