From 604f7ce55ad74694ef8743ad2e99933dc0265e46 Mon Sep 17 00:00:00 2001 From: Sanjeev Premi Date: Mon, 9 Nov 2009 22:43:00 +0530 Subject: [PATCH] Fix build failure in examples/standalone Some versions of 'make' do not handle trailing white-spaces properly. Trailing spaces in ELF causes a 'fake' source to be added to the variable COBJS; leading to build failure (listed below). The problem was found with GNU Make 3.80. Using text-function 'strip' as a workaround for the problem. make[1]: Entering directory `/home/sanjeev/u-boot/examples/standalone' arm-none-linux-gnueabi-gcc -g -Os -fno-common -ffixed-r8 -msoft-float -D__KERNEL__ -DTEXT_BASE=0x80e80000 -I/home/sanjeev/u-boot/include -fno-builtin -ffreestanding -nostdinc -isystem /opt/codesourcery/2009q1- 203/bin/../lib/gcc/arm-none-linux-gnueabi/4.3.3/include -pipe -DCONFIG_ ARM -D__ARM__ -marm -mabi=aapcs-linux -mno-thumb-interwork -march=armv5 -Wall -Wstrict-prototypes -fno-stack-protector -g -Os -fno-common -ff ixed-r8 -msoft-float -D__KERNEL__ -DTEXT_BASE=0x80e80000 -I/home/sanje ev/u-boot/include -fno-builtin -ffreestanding -nostdinc -isystem /opt/co desourcery/2009q1-203/bin/../lib/gcc/arm-none-linux-gnueabi/4.3.3/includ e -pipe -DCONFIG_ARM -D__ARM__ -marm -mabi=aapcs-linux -mno-thumb-inte rwork -march=armv5 -I.. -Bstatic -T u-boot.lds -Ttext 0x80e80000 -o .c arm-none-linux-gnueabi-gcc: no input files make[1]: *** [.c] Error 1 make[1]: Leaving directory `/home/sanjeev/u-boot/examples/standalone' make: *** [examples/standalone] Error 2 premi # Signed-off-by: Sanjeev Premi Fixed typo (s/ElF/ELF/).
