if you encounter this error on a rhel 5.5 box with your own built php > 5.2.2
make sure you upgrade pcre 6.6 to at least 7.6 (current ist 8.0.2).

• compile/build pcre with utf and unicode
• compile/build php with pcre-regex

default rhel pcre does not support unicode either. but this is not related to the warning below.

[Tue May 25 19:01:12 2010] [error] [client ....] PHP Warning:  preg_match() [function.preg-match]: Compilation failed: unrecognized character after (? at offset 2 in /usr/share/icinga-web/lib/agavi/src/util/AgaviDecimalFormatter.class.php on line 715, referer: https://hostname/icinga-web/

this error relates to agavi 1.0.3 and directly straight forward into preg_match (which is provided by pcre).

testscript for the extracted pattern (by writing a debugfile to disk and hacking agavi code currently)

just leaving that as feedback over here. just for php builds on rhel/centos.

ok a bit more testing on that. on a rhel 5.5 with built php 5.2.12 but pcre 6.6 it simply fails again with the warning, and login isn't possible.

so i would recommend to adapt the requirements for agavi/icinga-web then to:

= php 5.2.3
= pcre 7.6

• pcre in newer version
• compiled php 5.2.x based on this version (it's mandatory that php will be compiled ith the header files of newer pcre!)
