[PATCH 1/4] openbsc: add missing AC_LANG_SOURCE for current autoconf

autoconf >=2.68 demands the body of an AC_COMPILE_IFELSE to be wrapped in an AC_LANG_SOURCE macro, otherwise outputs annoying warnings on the invocation of `autoreconf -i`. this patch follows that demand. --- openbsc/configure.in | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/openbsc/configure.in b/openbsc/configure.in index e9bc079..74b3044 100644 --- a/openbsc/configure.in +++ b/openbsc/configure.in @@ -59,7 +59,7 @@ dnl Checks for typedefs, structures and compiler characteristics saved_CFLAGS="$CFLAGS" CFLAGS="$CFLAGS -fvisibility=hidden " AC_MSG_CHECKING([if ${CC} supports -fvisibility=hidden]) -AC_COMPILE_IFELSE([char foo;], +AC_COMPILE_IFELSE([AC_LANG_SOURCE([char foo;])], [ AC_MSG_RESULT([yes]) SYMBOL_VISIBILITY="-fvisibility=hidden"], AC_MSG_RESULT([no])) -- 1.7.5.rc3
