How to remove undefined symbol?

回答1:

The problem is at the following library:

/usr/lib/oracle/11.2/client64/lib/libclntsh.so.11.1

Change this library to an older version and it will work. We saw that the 11.2.0.4 version of the library is throwing this error while the 11.2.0.3 version just works.
