Cannot activate plugin

[Walter Ebert]

If I try to activate the plugin I get the following PHP error:

Fatal error: Cannot redeclare class SphinxClient in /home/wordpress/wp-content/plugins/wordpress-sphinx-plugin/php/sphinxapi.php on line 379 Call Stack: 0.0000 634392 1. {main}() /home/wordpress/wp-admin/plugins.php:0 1.5119 11225144 2. plugin_sandbox_scrape() /home/wordpress/wp-admin/plugins.php:151 1.5121 11236992 3. include('/home/wordpress/wp-content/plugins/wordpress-sphinx-plugin/sphinxsearch.php') /home/wordpress/wp-admin/plugins.php:149 1.5161 11320128 4. include_once('/home/wordpress/wp-content/plugins/wordpress-sphinx-plugin/php/sphinxapi.php') /home/wordpress/wp-content/plugins/wordpress-sphinx-plugin/sphinxsearch.php:60

I am using Wordpress 3.1.1 and PHP5.3.6

Hello,
Have you installed other version of WP Sphinx plugin or other plugin which use Sphinx Search?
If so, try to deactivate them, because they used the same library as WP Sphinx Plugin.

Turns out that I had the PHP Sphinx extension installed (http://pecl.php.net/package/sphinx)

In sphinxsearch.php you should probably add an extra check, e.g.:

if( !extension_loaded('sphinx') ) {
   if (file_exists(SPHINXSEARCH_SPHINX_INSTALL_DIR.'/api/sphinxapi.php'))
      include_once(SPHINXSEARCH_SPHINX_INSTALL_DIR.'/api/sphinxapi.php');
   else
    include_once(SPHINXSEARCH_PLUGIN_DIR.'/php/sphinxapi.php');
}

Thanks Walter, we will definitely add this to the next release.
