[Ruslan Osmanov]

Of course you can't. PHP7 is not backwards compatible, so the code has to be re-written to match the new API.

[Ruslan Osmanov]

Please check out php7 branch. The tests are passing.

I'm not merging to master because the code is different for pre-PHP7 versions. Currently, the PECL team has no idea how do we package PHP7 extensions.

[Aurimas Niekis]

Maybe release separate package for php7

[Ruslan Osmanov]

@aurimasniekis I'll build a universal package and upload it to PECL. Just a little busy these days.

[Ruslan Osmanov]

Uploaded universal package to PECL as ev 1.0.0RC1 (beta).

[Former user]

@osmanov : Is this something that should be working now with the universal package? Getting an error similar to (but different than) the original poster. PECL package 1.0.0RC9 (beta) for PHP 7.0.4:

[Ruslan Osmanov]

@frickenate you're trying to build version ev-0.2.15. I guess you're running sudo pecl install ev which pulls the stable version. But the latest version (1.0.0RC9) is beta. So the command should be sudo pecl install ev-beta

[Former user]

Ah thanks, that did the trick. And now I learn this is a separate implementation from the pecl package (which is not included in the pecl repo) that React supports. I see some effort has been put into trying to add support for your implementation into React ( most recently https://github.com/reactphp/event-loop/pull/25 ), though apparently without success as of yet. How unfortunate, considering the supported implementation is all but abandoned by the developer (no php 7 support anytime soon).

[Ruslan Osmanov]

@frickenate, I'm open to communication, anyway. There are no open issues in the tracker so far, except the one regarding Windows package.
