From dd7595a3475407a7fa96a97393bae8c5220e8762 Mon Sep 17 00:00:00 2001 From: David Walter Seikel Date: Wed, 4 Jan 2012 18:41:13 +1000 Subject: Add the base Enlightenment Foundation Libraries - eina, eet, evas, ecore, embryo, and edje. Note that embryo wont be used, but I'm not sure yet if you can build edje without it. --- libraries/ecore/m4/efl_threads.m4 | 206 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 206 insertions(+) create mode 100644 libraries/ecore/m4/efl_threads.m4 (limited to 'libraries/ecore/m4/efl_threads.m4') diff --git a/libraries/ecore/m4/efl_threads.m4 b/libraries/ecore/m4/efl_threads.m4 new file mode 100644 index 0000000..33d15a3 --- /dev/null +++ b/libraries/ecore/m4/efl_threads.m4 @@ -0,0 +1,206 @@ +dnl Copyright (C) 2010 Vincent Torri +dnl rwlock code added by Mike Blumenkrantz +dnl This code is public domain and can be freely used or copied. + +dnl Macro that check if POSIX or Win32 threads library is available or not. + +dnl Usage: EFL_CHECK_THREADS(ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]) +dnl Call AC_SUBST(EFL_PTHREAD_CFLAGS) +dnl Call AC_SUBST(EFL_PTHREAD_LIBS) +dnl Defines EFL_HAVE_POSIX_THREADS or EFL_HAVE_WIN32_THREADS, and EFL_HAVE_THREADS + +AC_DEFUN([EFL_CHECK_THREADS], +[ + +dnl configure option + +AC_ARG_ENABLE([posix-threads], + [AC_HELP_STRING([--disable-posix-threads], [enable POSIX threads code @<:@default=auto@:>@])], + [ + if test "x${enableval}" = "xyes" ;
