Subject: [U-Boot] u-boot fails to build for powerpc with gcc 4.5.1
Date: Thu, 31 Mar 2011 15:27:12 -0700	[thread overview]
Message-ID: <4D94FFC0.7010700@linux.intel.com> (raw)

The u-boot recipe in Poky (OE core) fails to build u-boot for powerpc.
I've tested the following versions:

v2010.09
v2010.12
v2011.03

All versions fail with:
$ make ARCH=powerpc
CROSS_COMPILE=/opt/poky/1.0/sysroots/x86_64-pokysdk-linux/usr/bin/ppc603e-poky-linux/powerpc-poky-linux-
MPC8315ERDB_config
awk '(NF && $1 !~ /^#/) { print $1 ": " $1 "_config; $(MAKE)" }' boards.cfg >

Generating include/autoconf.mk.dep
cc1: error: Do not use -Os option if --enable-target-optspace is not set.

I got past this with:

 ifeq ($(CONFIG_NAND_U_BOOT),y)



v2010.09 fails with:
crc32.c:85:1: error: initializer element is not constant crc32.c:85:1: error: (near initialization for 'crc_table[0]') 
This appears to be fixed in later versions.


v2010.12 and v2011.03 fail with:
ehci-hcd.c:59:3: error: initializer element is not constant

Full build logs are available in the bug report here:
