Проблемы работы на некоторых серверах с PHP-5.2.10+ и ZendOptimizer до 3.3.3 включительно

What I had done?!

1. I went to. zend.com
2. Registered
3. Go to «Home -> Products -> Zend Guard -> Zend Optimizer»
4. Click on «No thanks, download only the Zend Optimizer runtime»
URL is:
Code:
http://www.zend.com/products/guard/downloads

5. Select Release: Zend Optimizer v3.3
6. Downloaded ZendOptimizer-3.3.9-freebsd6.0-i386.tar.gz
7. Unpacked archive
8. Copied file:
Code:

ZendOptimizer-3.3.9-freebsd6.0-i386/data/5_2_x_comp/ZendOptimizer.so

to:
Code:

/usr/local/lib/php/zend/ZendOptimizer.so

9. Then in php.ini added the line:
Code:

zend_extension=»/usr/local/lib/php/zend/ZendOptimizer.so»

10. Stopped Apache Server
11. Started Apache Server
12. After that in Apache server error log file
(the path can be found in your Appache configuration file, look for «ErrorLog» option)
I noticed this one line:
Code:

Failed loading /usr/local/lib/php/zend/ZendOptimizer.so: Shared object «libm.so.4» not found, required by «ZendOptimizer.so»

13. Used some Google with search request:

14. And got a good help URL about this problem ->
Code:

http://sasuke.tistory.com/80

15. Just executed these commands:
Code:

cd /lib
ln -s /lib/libm.so.5 /lib/libm.so.4
ln -s /lib/libutil.so.7 /lib/libutil.so.5
ln -s /lib/libcrypt.so.4 /lib/libcrypt.so.3
ln -s /lib/libc.so.7 /lib/libc.so.6

16. Stopped Apache Server
17. Started Apache Server
18. And Working!
