Tested with phpize too and I obtained the same result. By the way the "phpize"
way is simply
not feasible for me/us and, if phpize makes it, Visual Studio should be able to
make it too,
right ?.
Please find my "phpize" project here :
http://www.neologica.it/test_ext_phpize.7z
I must admint I never used phpize before on windows and I didn't think it was
fully Windows
compatible, however here is what I did (everything is provided with the 7z
archive):
1] Created the "test" folder under "php_5.4/include/ext"
2] Moved my source files in this folder
3] Created the config.w32 file
4] Opened the Visual Studio 2008 command prompt and moved to this folder
5] ..\..\..\phpize.bat
6] configure.bat --enable-test (here I had to add "bison.exe" location to my
"PATH" and in
the configure.js file I needed to add PHP_PGI and PHP_PGO definition)
7] nmake
and the result was the same as before.

This callback is part of the build (while interned string are only implemented
in
NTS).
Please check a build of your ext using the supported ways, phpize or to build
with
php to double check the actual problem.

Description:
------------
I have a PHP extension which adds some "native" functions and zend classes to
the PHP framework.
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)
