I‘m trying to configure and install xcache under CentOS / Redhat enterprise Linux v5.4 and getting the following error:

/usr/include/php/ext/date/lib/timelib_structs.h:24:28: error: timelib_config.h: No such file or directory

How do I fix this problem and install xcache?

This is well known problem and it can be easily fixed by editing the /usr/include/php/ext/date/lib/timelib_structs.h file itself. Type the following command to edit the file, run:

# vi /usr/include/php/ext/date/lib/timelib_structs.h
Find line:

#include <timelib_config.h>

Replace / update as follows:

#include "timelib_config.h"

Save and close the file. Now, you can compile the xcache:
# make install
