Couldn't find any package by regex libstdc++.so.5 libexpat.so.0 in 32-bit
ubuntu 12.04

While installing a software wink, I got stdc++ and lib expat packages not
found.
prayag@prayag:~/wink$ ./installer.sh
Wink requires that the following packages be installed to run properly.
Please install them and try again.
libstdc++.so.5 libexpat.so.0
Then I tried installing above packages via apt-get, but am getting
prayag@prayag:~/wink$ sudo apt-get install libstdc++.so.5

E: Unable to locate package libstdc++.so.5

prayag@prayag:~/wink$ sudo apt-get install libexpat.so.0

How can I get them in 32-bit ubuntu and make the wink installation move on.
