[jira] [Commented] (MESOS-8457) Build failure on macOS 10.13 due to the syscall deprecation.

["Till Toenshoff (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MESOS-8457?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16347757#comment-16347757 ] 

Till Toenshoff commented on MESOS-8457:
---------------------------------------

While there is not real solution available right now - one workaround is making sure that warnings to not get elevated to errors: {{--disable-werror}}.

We should however find a proper solution here. The options clearly are:
 * prevent the syscall on macOS by implementing Apple's new alternative
 ** have not been able to find something for these purposes
 * add warning suppressions to our build system depending on the platform
 * surround the specific code with local warning suppressions via {{#pragma}}
