From 46bab7e4b921b79924643bacd08dcd3d1404ceb6 Mon Sep 17 00:00:00 2001 From: Denis Krjuchkov Date: Wed, 27 Nov 2013 17:04:38 +0600 Subject: Add infrastructure for using multiple event loops This change adds two configuration options: --with-eventloop=[glib|internal|auto] --with-pollmethod=[epoll|auto] First allows switching between GLib event loop and internal one. Second chooses backend to use for internal event loop. Conditional compilation symbols are changed accordingly. Additional helper macro MPD_OPTIONAL_FUNC_NODEF is added as well. --- m4/mpd_func.m4 | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'm4/mpd_func.m4') diff --git a/m4/mpd_func.m4 b/m4/mpd_func.m4 index d12d27062..5f2bf8f3d 100644 --- a/m4/mpd_func.m4 +++ b/m4/mpd_func.m4 @@ -10,3 +10,16 @@ AC_DEFUN([MPD_OPTIONAL_FUNC], [ [AC_CHECK_FUNC([$2], [AC_DEFINE([$3], 1, [Define to use $1])],)]) ]) + +dnl MPD_OPTIONAL_FUNC_NODEF(name, func) +dnl +dnl Allow the user to enable or disable the use of a function. +dnl Works similar to MPD_OPTIONAL_FUNC, however MPD_OPTIONAL_FUNC_NODEF +dnl does not invoke AC_DEFINE when function is enabled.
