From 73652fa06c449f55b844890778c4cb592e0df62e Mon Sep 17 00:00:00 2001 From: Mark Wielaard Date: Fri, 27 Jan 2023 15:23:15 +0100 Subject: [PATCH 2/4] configure.ac: Use AC_LINK_IFELSE for -gz=none check Because of a bug in gcc 13.0 (pre-release) -gz=none does not work correctly when linking the final binary in some situations (when -gz=zstd isn't supported). Work around this by explicitly checking for support with AC_LINK_IFELSE. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108572 Signed-off-by: Mark Wielaard --- configure.ac | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/configure.ac b/configure.ac index f2d1571..1d77e99 100644 --- a/configure.ac +++ b/configure.ac @@ -125,7 +125,7 @@ AC_SUBST([DWARF_5_DEBUGLINE]) AC_CACHE_CHECK([whether gcc supports -gz=none], ac_cv_gz_none, [dnl save_CFLAGS="$CFLAGS" CFLAGS="-gz=none" -AC_COMPILE_IFELSE([AC_LANG_SOURCE()], ac_cv_gz_none=yes, ac_cv_gz_none=no) +AC_LINK_IFELSE([AC_LANG_SOURCE()], ac_cv_gz_none=yes, ac_cv_gz_none=no) CFLAGS="$save_CFLAGS" ]) if test "$ac_cv_gz_none" = "yes"; then -- 2.39.1
