The manpage is blank when centos5.4 encounters a problem!

The manpage is blank when centos5.4 encounters a problem! -- Linux general technology-Linux technology and application information. For details, refer to the following section. The original man page prompts that libstdc ++. so.6 could not be found. After I link it to libstdc ++-3-libc6.2-2.10.0.so, no error is reported. A large white space is displayed and an END is located in the lower left corner. ,
The following are related files in lib and variables such as paths.
