install_driver(Oracle) failed: Can’t load `…/DBD/Oracle/’ for module DBD::Oracle


This section is from the "Practical mod_perl " book, by Stas Bekman and Eric Cholet . Also available from Amazon: Practical mod_perl

Here’s an example of the full error report that you might see:

install_driver(Oracle) failed: Can't load
for module DBD::Oracle: cannot open shared object file:
No such file or directory at
/usr/lib/perl5/5.6.1/i386-linux/ line 169.
at (eval 27) line 3
Perhaps a required shared
library or dll isn't installed where expected at
/usr/local/apache/perl/ line 11

On BSD-style filesystems, LD_LIBRARY_PATH is not searched for setuid programs. If Apache is a setuid executable, you might receive this error. Therefore, the first solution is to explicitly load the library from the system-wide ldconfig configuration file:

panic# echo $ORACLE_HOME/lib >> /etc/
panic# ldconfig

Another solution to this problem is to modify the Makefile file (which is created when you run perl Makefile.PL ) as follows:

  1. Search for the line LD_RUN_PATH=

  2. Replace it with LD_RUN_PATH=my_oracle_home/lib

where my_oracle_home is, of course, the home path to your Oracle installation. In particular, the file should exist in the lib subdirectory.

Then just type make install , and all should go well.

Note that setting LD_RUN_PATH has the effect of hardcoding the path to my_oracle_home/lib in the file , which is generated by DBD::Oracle . This is an efficiency mechanism, so that at runtime it doesn’t have to search through LD_LIBRARY_PATH or the default directories used by ld.

For more information, see the ld manpage and the essay on LD_LIBRARY_PATH at .
