Problems with installing ORACLE on Ubuntu 9.04

Oracle 9.04 is installed on Ubuntu Server 10.2 today. When it is installed to 80%, the all_no_orcl error occurs.
Open the log file as prompted and find the following error:
Information: Creating/opt/oracle/lib/liborasdkbase. so.10.2

Information: gcc:
Information:/usr/lib/libstdc ++. so.5: the file or directory does not exist.
Information:

Information:/opt/oracle/bin/genorasdksh: Failed to link liborasdkbase. so.10.2

Message: make: *** [liborasdkbase] Error 1

It turns out that the libstdc ++ package is incorrect. After check, the libstdc ++ 5 package should be installed, but when the system installs other programs
Libstdc ++ 6 package has been installed, so libstdc ++ 5 is not installed
So how can we solve this problem? By searching through multiple parties, you can use the method of fish and eye ball as follows:
Open another terminal and execute the following command
Cd/usr/lib
Ln-s libstdc ++. so.6 libstdc ++. so.5

Return to the Oracle Installation page and try again.
