libcxa.so.3 not found

Dear all,
     I have recently downloaded the xerces XML parser for linux and trying
to run the sample programs. The error given by the program is libcxa.so.3
not found. This file was not found on my linux machine. Should I install any
other package where I can find this file.
     I am currently using Redhat 7.1 version of linux.

Thanks & regards
Mandar Khire
