After installing wordpress, I got a lot of these errors in my apache wordpress error log.
PHP Warning: preg_match_all() [<a href='function.preg-match-all'>function.preg-match-all</a>]: Compilation failed: this version of PCRE is not compiled with PCRE_UTF8 support at offset 0 in ...
I am running apache 2.2.8 and it uses the built-in version 5 of pcre.
http://httpd.apache.org/docs/2.2/new_features_2_2.html
The problem is that version 5 of pcre does not contain UTF-8 support. So I had to recompile apache with a newer version of pcre. Luckily I have pcre 6.6 already installed on my linux box.
>> rpm -qa |grep -i pcre pcre-devel-6.6-2.el5_0.1 pcre-6.6-2.el5_0.1 pcre-6.6-2.el5_0.1
So all I had to do is re-compile apache with the “–with-pcre” flag.
./configure --with-pcre
If you don’t know what version of pcre your php is using, create a phpinfo script and hit it with your broswer. You should see…
Happy compiling…
