I've built Apache, PHP and XCache by hand but am having problems getting XCache 3.0 to load. XCache 2.0.1 loads with no problem. This happened with PHP 5.4.7 so I upgraded to PHP 5.4.8 but have the same issue.

When I have the following line in my php.ini file:
  extension = /usr/local/lib/php/extensions/no-debug-non-zts-20100525/xcache.so

I get the error message "/usr/local/lib/php/extensions/no-debug-non-zts-20100525/xcache.so doesn't appear to be a valid Zend extension" and Apache will not start.

If I change this to:
   zend_extension = /usr/local/lib/php/extensions/no-debug-non-zts-20100525/xcache.so

Apache starts, but the extension is not loaded. Here is the output of "php-cgi -v":

/usr/local/lib/php/extensions/no-debug-non-zts-20100525/xcache.so doesn't appear to be a valid Zend extension
PHP 5.4.8 (cgi-fcgi) (built: Nov  2 2012 18:41:20)
Copyright (c) 1997-2012 The PHP Group
Zend Engine v2.4.0, Copyright (c) 1998-2012 Zend Technologies
    with the ionCube PHP Loader v4.2.2, Copyright (c) 2002-2012, by ionCube Ltd

If I compile version 2.0.1 it installs to the same location and works perfectly.

Any thoughts on what might be going wrong? I have tried this on two servers that have this issue. The other server is running PHP 5.4.8 and nginx.

Thanks.

search xcache.so in your php ini files, you might have old settings left there
"extension = xcache.so" would be the right since 3.0

I only have one line:
   zend_extension = "/usr/local/lib/php/extensions/no-debug-non-zts-20100525/xcache.so"

I deleted all the old lines and copied the xcache.ini just to make sure and did not have any luck.

As I mentioned, it works perfectly with 2.0.1 without any changes. If this helps, I compiled 3.0.0 with:

$ phpize --clean && phpize
$ ./configure --enable-xcache --enable-xcache-optimizer
$ make
$ make install

read release note
with 3.0, xcache.so is no longer a Zend Extension but a PHP extension
remove zend_extension = */xcache.so. load it using extension = ..

Thanks, that does appear to work but only if I comment out the ioncube loader line in php.ini:

  ;zend_extension = /usr/local/ioncube/ioncube_loader_lin_5.4.so

If i try and load both ioncube and xcache, I get the error:

  PHP Fatal error:  [ionCube Loader] The Loader must appear as the first entry in the php.ini file in Unknown on line 0

If I comment out xcache, this works fine. It also works with xcache 2.

Are ioncibe and xcache 3 not compatible?

Thanks.

please edit xcache.c
find lines
typedef struct {
const char *name;
startup_func_t old_startup;
} xc_incompatible_zend_extension_info_t;
static xc_incompatible_zend_extension_info_t
xc_incompatible_zend_extensions[] = {
{ "Zend Optimizer", NULL }
};


change
{ "Zend Optimizer", NULL }
to
{ "Zend Optimizer", NULL },
{ "ionCube Loader", NULL }

recompile, reinstall. see if works for you without any problem at runtime

Sorry, same error when the ioncube loader line is not commented out:

# php-cgi -v
PHP Fatal error:  [ionCube Loader] The Loader must appear as the first entry in the php.ini file in Unknown on line 0      

When I comment it out:

I had the same problem: "...xcache.so doesn't appear to be a valid Zend extension" and Apache will not start.". I solved changing the line zend_extension to extension (removing the "zend"), just like you said. I would like to ask if there is more thing that I would change in my old .ini file from Xcache 2 when upgrading to version 3.0.0 or if the ini can still be the same?

Sorry, that does not seem to work either:

# php-cgi -v
PHP Fatal error:  [ionCube Loader] The Loader must appear as the first entry in the php.ini file in Unknown on line 0                          

xcache.c:

Unfortunately, no luck with that either. Thanks again for the help.

Hi moo,

Yep, with the latest trunk version 1178, XCache 3.0.1-dev and ionCube 4.2.2 are loading -- well they are on my nginx + php-fpm server.

it's ok. latest trunk is 1190
lighttpd sort directory list in string instead of numeric way so 1*
come before 9*

you didn't read Release note, not even this discussion thread
use extension=xcache.so to load instead of zend_extension=/path/to/xcache.so
