with the patch

to pass the configure

[fpoirotte]

Commit 86b43c3 introduced the notion of API restrictions.
These restrictions are based on the new preload RFC that has recently been added to PHP's master branch (see https://wiki.php.net/rfc/preload & php/php-src@f6d227e).
Unfortunately, this means that PHP must have been compiled from a nightly snapshot / fresh clone;

Keep in mind that this extension is still pretty new: the API may still change (see recent commits related to FFI:cdef, FFI::typeof, FFI::arrayType and so on).

@yanggs07 @fpoirotte this extension is going to be part of PHP 7.4 (7.3 is not supported, however it might be possible to make it compatible)
