CiviCRM Community Forums (archive)

Hi guys, bit of help required if possible. I am getting the errors pasted below at the top of each page in a pink box


    * warning: preg_replace() [function.preg-replace]: Compilation failed: PCRE does not support \L, \l, \N, \P, \p, \U, \u, or \X at offset 6 in /home/sites/mywebsite.org.uk/public_html/cms/sites/all/modules/civicrm/packages/IDS/Converter.php on line 571.

These appear on each CiviCRM page on the admin pages. There can be a list of 4 errors up to about 20, but they are the same 2 line numbers.
It doesn't seem to cause any noticeable interference with the admin side of things, although in the background there maybe something I have missed.

This is a completely clean Drupal installation. I reinstalled this for the second time as it had the same faults the first time round

CiviCRM:     2.1 Alpha 4
CMS:    Drupal 6.4
MySQL:    5.0.67
PHP:    5.2.5

Any suggestions would gratefully received Also, I am new to this with a little knowledge, and a little knowledge can be a dangerous thing!

Let me know if more detail is required.

Thanks

Like GSterr, I'm getting lots of errors, such as:

# warning: preg_replace() [function.preg-replace]: Compilation failed: PCRE does not support \L, \l, \N, \P, \p, \U, \u, or \X at offset 6 in /home/sites/ruralchina.org/public_html/rcef/sites/all/modules/civicrm/packages/IDS/Converter.php on line 553.

# warning: preg_replace() [function.preg-replace]: Compilation failed: PCRE does not support \L, \l, \N, \P, \p, \U, \u, or \X at offset 6 in /home/sites/ruralchina.org/public_html/rcef/sites/all/modules/civicrm/packages/IDS/Converter.php on line 571.
Which correspond to the following two lines in Converter.php:

Line 553:
$stripped_length = strlen(preg_replace('/[\w\s\p{L}.,\/><]*/ms', null, $tmp_value));
Line 571:
// Replace all non-special chars
$converted =  preg_replace('/[\w\s\p{L}]/', null, $value);
And it would seem the problem is that my version of the PCRE is very old: phpinfo tells me it's version 4.5 from 2003. As a consequence it doesn't support unicode characters, meaning \p{L} won't work. It would seem that I need PCRE version 5.1 at least to support this. I'll ask my hosting provider if they can upgrade, but I wouldn't bet on it...

My question is, is there another regular expression that I can use that would be "good enough" and let me run CiviCRM without these ugly error messages? I'm not familiar with regular expressions at all so don't have the know how to do it myself at the moment. And is it a good idea to fudge such a solution, as my site will undoubtedly be using unicode characters (Chinese).

I am now using the production version 5.2.8, and am still experiencing the issues mentioned above.  Has there been any progress on this issue?

Thanks

If you're getting these errors, then the issue is about your installed version of PCRE (the perl regular expression library) not supporting unicode.

I think lobo's pointing you to that site because CiviCRM uses a third party package from them, which is what generates the errors.

The short answer is:

1. you can hack the library to make this work.

2. it's better to upgrade your pcre, though it might not be easier.

Here's a summary of my experience:
