Here’s an example of the full error report that you might see:
install_driver(Oracle) failed: Can't load
'/usr/lib/perl5/site_perl/5.6.1/i386-linux/auto/DBD/Oracle/Oracle.so'
for module DBD::Oracle:
libclntsh.so.8.0: cannot open shared object file:
No such file or directory at
/usr/lib/perl5/5.6.1/i386-linux/DynaLoader.pm line 169.
at (eval 27) line 3
Perhaps a required shared
library or dll isn't installed where expected at
/usr/local/apache/perl/tmp.pl 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/ld.so.conf
panic# ldconfig
(使用该方法我的问题就解决了)
Another solution to this problem is to modify the Makefile file (which is created when you run perl Makefile.PL ) as follows:
-
Search for the line LD_RUN_PATH=
-
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 libclntsh.so.8.0 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 Oracle.so , 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 http://www.visi.com/~barr/ldpath.html .
It?¦s actually a nice and helpful piece of information. I am satisfied that you shared this helpful information with us. Please stay us up to date like this. Thanks for sharing.
我也碰到这样的问题，这两种方法都试过了，还是不行。
