PHP 4.0 Bug #7308 Updated: Error of link of apache 1.3.14 with an UNSATISFIED SYMBOLS.

ID: 7308 Updated by: jimjag Reported By: Michel.Gaudet@ehess.fr Status: Closed Bug Type: Compile Failure Assigned To: Comments: This is due to an error in the zend_extensions.c file in the Zend directory. The call to DL_UNLOAD should be protected by a macro that ensures it exists. This is fixed in CVS, but to fix your copy, the change is very easy. Just edit zend_extensions.c and look for static void zend_extension_startup (line 142) and change it to look like: <pre> static void zend_extension_startup(zend_extension *extension) { #if ZEND_EXTENSIONS_SUPPORT if (extension->startup) { if (extension->startup(extension)!=SUCCESS) { DL_UNLOAD(extension->handle); } } #endif } </pre> Note the addition of the #preprocessor line.

Is it a problem with the HP config or a bug ? --------------------------------------------------------------------------- Full Bug description available at: http://bugs.php.net/?id=7308
