What kind of version EIO must be used for this library?

UPD.

https://pecl.php.net/package-changelog.php?package=eio&release=2.0.3

2.0.2 | Fixed build error due to undefined O_FSYNC in musl libc

@WyriHaximus What do you think about this issue?

[WyriHaximus]

@valVk I'd 1.0 and 2.0 but this has to be fixed. Either by removing the use of that constant or by adding a polyfill. Not sure yet, leaning torwards the former

[valVk]

Thanks for your clarification. I think, that information about EIO's version has to be added to the Readme.

[WyriHaximus]

@valVk dropping it in v0.1.2/v0.2 as f isn't supported by PHP either and EIO also dropped it. PR is up at #44

[kelunik]

@WyriHaximus It's conditionally defined, it didn't get dropped: https://github.com/rosmanov/pecl-eio/commit/65e8b5433992c77c5290d23d8ae33b58499c44a1#diff-0cc087e71ac0c866a224fb4846b3314dR932
