From c459d509b7c7fe7d8200ea3791d1ef0b245126ab Mon Sep 17 00:00:00 2001 From: "Wladimir J. van der Laan" Date: Sun, 5 Mar 2017 09:29:37 +0000 Subject: build: Probe MSG_DONTWAIT in the same way as MSG_NOSIGNAL Instead of the WIN32-specific workaround, detect lack of `MSG_DONTWAIT` in the build system. This allows other platforms without `MSG_DONTWAIT` to work too. --- configure.ac | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'configure.ac') diff --git a/configure.ac b/configure.ac index d25bebeb1a..65f7fa0739 100644 --- a/configure.ac +++ b/configure.ac @@ -558,6 +558,15 @@ AC_COMPILE_IFELSE([AC_LANG_PROGRAM([[#include ]], [ AC_MSG_RESULT(no)] ) +dnl Check for MSG_DONTWAIT +AC_MSG_CHECKING(for MSG_DONTWAIT) +AC_COMPILE_IFELSE([AC_LANG_PROGRAM([[#include ]], + [[ int f = MSG_DONTWAIT; ]])], + [ AC_MSG_RESULT(yes); AC_DEFINE(HAVE_DONTWAIT, 1,[Define this symbol if you have MSG_DONTWAIT]) ], + [ AC_MSG_RESULT(no)] +) + + AC_MSG_CHECKING([for visibility attribute]) AC_LINK_IFELSE([AC_LANG_SOURCE([ int foo_def( void ) __attribute__((visibility("default"))); -- cgit v1.2.3
