+Subject: [PATCH] kconfig/lxdialog: fix check() with GCC14
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+GCC14 now treats implicit int types as error so when check() from
+check-lxdialog.sh is called to check whether we can link against ncurses
+it will fail silently and the help text indicating to install ncurses is
+printed.
+
+However, this is not due to missing ncurses but once the stderr redirect
+to /dev/null is removed we can see the root cause:
+<stdin>:2:1: error: return type defaults to ‘int’ [-Wimplicit-int]
+
+So, in order for menuconfig to work with GCC14 lets just specify the
+return type of main() as int.
