Missing libstdc++.so.5 in Ubuntu 9.10

今天下載了一個執行檔要執行，結果出現了
missing libstdc++.so.5 的錯誤
google了一下發現是因為ubuntu 9.10拿掉了這個library
參考了這篇網誌的內容

1.In debian's website download libstdc++5 (according to your machine&location)

wget http://debian.linux.org.tw/debian/pool/main/g/gcc-3.3/libstdc++5_3.3.6-18_i386.deb
(you can find different download source to download this package)

2. unpack this package

dpkg-deb -x libstdc++5_3.3.6-18_i386.deb ia32-libs

3. move library to /usr/lib and make a symbolic link

cd ia32-libs/usr/lib
sudo cp libstdc++.so.5.0.7 /usr/lib/
cd /usr/lib
sudo ln -s libstdc++.so.5.0.7 libstdc++.so.5
