From 5ae6fcc4bb82bd05996cc685b8786c586637e56d Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 2 Mar 2018 16:05:12 +0900 Subject: kconfig: fix line number in recursive inclusion error message When recursive inclusion is detected, the line number of the last 'included from:' is wrong. [Test Case] Kconfig: -------->8-------- source "Kconfig2" -------->8-------- Kconfig2: -------->8-------- source "Kconfig3" -------->8-------- Kconfig3: -------->8-------- source "Kconfig" -------->8-------- [Result] $ make allyesconfig scripts/kconfig/conf --allyesconfig Kconfig Kconfig:1: recursive inclusion detected. Inclusion path: current file : 'Kconfig' included from: 'Kconfig3:1' included from: 'Kconfig2:1' included from: 'Kconfig:3' scripts/kconfig/Makefile:89: recipe for target 'allyesconfig' failed make[1]: *** [allyesconfig] Error 1 Makefile:512: recipe for target 'allyesconfig' failed make: *** [allyesconfig] Error 2 where we expect current file : 'Kconfig' included from: 'Kconfig3:1' included from: 'Kconfig2:1' included from: 'Kconfig:1' The 'iter->lineno+1' in the second fpinrtf() should be 'iter->lineno-1'. I refactored the code to merge the two fprintf() calls.
