From 60f33b80443a3e7e79e2a3ddc625ab6246a61d3d Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Sun, 15 Jan 2006 15:28:35 +0100 Subject: kconfig: get rid of stray a.o, support ncursesw scripts/kconfig/lxdialog/check-lxdialog.sh uses gcc to check for what libraries are present. Redirect output to /dev/null so we do not generate an a.out. Also included support for ncursesw - so if present prefer that instead of ncurses. The order is now (first is preferred): 1) ncursesw 2) ncurses 3) curses The latter is to support SunOS.

Also introduce KERNELVERSION - only user is kconfig. KERNELVERSION was needed to display kernel version in menuconfig - KERNELRELEASE is not valid until configuration has completed. kconfig files modified to use KERNELVERSION.
