[asterisk-bugs] [JIRA] (DAHLIN-366) DAHDI 3.0.0 + CentOS 7 = "error: conflicting types for ‘timer_setup’"

[Keith Morgan (JIRA)]

    [ https://issues.asterisk.org/jira/browse/DAHLIN-366?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=246112#comment-246112 ] 

Keith Morgan commented on DAHLIN-366:
-------------------------------------

DAHDI 3.0 will only compile on kernels 4.15 or newer. 

"The setup_timer functions were removed in upstream kernel v4.15, and therefore
this change is needed in order to compile DAHDI for kernels >= 4.15."

Use DAHDI 2.11.1 for older kernels.
