If you try installing Intel Fortran Compiler on Ubuntu 10.10 Maverick Meerkat or 10.04 Lucid Lynx or Karmic Koala, it is going to throw the error: error while loading shared libraries: libstdc++.so.5
The original libstdc++5 package is no longer available with the Ubuntu 9.10 repos. So for 32 bit system you would have to get it from Debian Repository .
Install
it and you are good to go if you are using the 32 bit OS.
For 64 bit it is a bit complicated, first install libstdc++5 64bit and then do the following:
wget http://security.ubuntu.com/ubuntu/pool/universe/i/ia32-libs/ia32-libs_2.7ubuntu6.1_amd64.deb
dpkg-deb -x ia32-libs_2.7ubuntu6.1_amd64.deb ia32-libs
sudo cp ia32-libs/usr/lib32/libstdc++.so.5.0.7 /usr/lib32/
cd /usr/lib32
sudo ln -s libstdc++.so.5.0.7 libstdc++.so.5
