I'm however quite confused, this same #include worked well for php5.3 without the "extern" thing. I took a look at, for example, "zend.h" header and I saw that all the declaration marked as ZEND_API are also wrapped by the "BEGIN_EXTERN_C()" and "END_EXTERN_C()" macros, but, inside the header "zend_string.h" which is the one causing me this link problem, all the ZEND_API declaration are not wrapped by those 2 macros. Is there some particular reason for this ? I also found that, now that you've enlightened me, another solution to my problem is to wrap those function in the zend_string.h like this: BEGIN_EXTERN_C() // was missing previosly ZEND_API extern const char *(*zend_new_interned_string)(const char *str, int len, int free_src TSRMLS_DC); ZEND_API extern void (*zend_interned_strings_snapshot)(TSRMLS_D); ZEND_API extern void (*zend_interned_strings_restore)(TSRMLS_D); END_EXTERN_C() // was missing previosly But in this case I really don't know if it works by chance or if it was really meant to be like it was before. Thank you for you help!

Make sure you're including the PHP headers inside an extern "C" {} block. ------------------------------------------------------------------------ [2012-07-24 12:15:42] pajoye@php.net No idea about sln, it may differ as phpize generates some data. About another test, can you try to build it with php? php-sdk\vc9\x86 |_ php-src |_ pecl |_ yourext run buildconf from php-src, then: configure <options needed> etc. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
