Building V8JS on Debian Bullseye with support for PHP 8.2 and V8 11.1

[magdutra]

I had compiled both V8 and V8JS before, but moved to PHP 8.2 now due to the end of support of PHP 7.4.

I have successfully compiled V8 11.1 on my Debian Bullseye. However, when running "configure" in preparation to build V8JS, it reported that the libv8 version could not be detected. After reading issue #490, I manually changed the version of c++14 to c++17 in the "configure" script, and could proceed further.

Then, I got a compilation error complaining about the "ShutdownPlatform" function. I replaced it by "DisposePlatform" and tried again. Now I'm getting the following error, for which I have no clue how to recover from:

/usr/local/src/v8js/v8js_v8object_class.cc: In function ‘zend_result zm_startup_v8js_v8object_class(int, int)’: /usr/local/src/v8js/v8js_v8object_class.cc:924:39: error: invalid conversion from ‘int ()(zend_object, zend_class_entry, zend_function, zend_object, bool)’ {aka ‘int ()(_zend_object, _zend_class_entry, _zend_function, _zend_object, bool)’} to ‘zend_object_get_closure_t’ {aka ‘ZEND_RESULT_CODE ()(_zend_object, _zend_class_entry, _zend_function, _zend_object**, bool)’} [-fpermissive] 924	v8js_v8object_handlers.get_closure = v8js_v8object_get_closure;	^~~~~~~~~

make: *** [Makefile:257: v8js_v8object_class.lo] Error 1

Is it possible to build V8JS in the PHP8 branch for V8 version 11?
