Please check a build of your ext using the supported ways, phpize or to build with php to double check the actual problem.

This extension is located out of the php source tree and it is built using a Visual Studio 2008 project which should set all the preprocessor definitions and .lib needed. In order to build this extension i'm linking it to the php5ts.lib file included inside the php-devel-pack (which can be downloaded from here http://windows.php.net/downloads/releases/archives/) and, of course, including the *.h files provided with the php-devel-pack. My Visual Studio solution worked fine using php5.2 and php5.3 includes and libs but it fails the compilation using the php5.4 php-devel-pack. In particular I receive a link error: unresolved external symbol "__declspec(dllimport) char const * (__cdecl* zend_new_interned_string)(char const *,int,int,void * * *)" (__imp_?zend_new_interned_string@@3P6APBDPBDHHPAPAPAX@ZA) as if that symbol were not available from the php5ts.lib file. I've generated a simpler Visual Studio solution containing ALL the files needed to build which should present the issue. The solution can be downloaded here: http://www.neologica.it/test_ext_vc9.7z The source code contains a simple php extension and a zend class declaration (Test) having a method: "sayHello". Compiling it using the configuration *_5.3 should produce the dll correctly while using the *_5.4 configuration should trigger the link error. I'm not sure if this is some unfortunate case of undeclared macro in my code / solution, or if there is something that could be done in php source. Test script: --------------- 1 - Extract the archive 2 - Open the solution with Visual Studio (2008 or 2010 is the same) 3 - Select "Release_5.4" or "Debug_5.4" from the build Solution configurations dropdown 4 - Build the extension. Expected result: ---------------- php_test.dll correctly built Actual result: -------------- error LNK2001: unresolved external symbol "__declspec(dllimport) char const * (__cdecl* zend_new_interned_string)(char const *,int,int,void * * *)" (__imp_? zend_new_interned_string@@3P6APBDPBDHHPAPAPAX@ZA) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62651&edit=1
