Re: [Ltib] imx53 QSB on Ubuntu 12.04

[Bair, Richard]

1) In the downloaded BSP tree the command grep -R CONFIG_TOOLCHAIN= * | less 
yields the following....I don't see a defconfig file but surmise the imx51.cf 
and similar are representative of the BSP setup:

config/profile/swang-poc.config:CONFIG_TOOLCHAIN="freescale-powerpc-linux-gnu-4.1-69.i686.rpm"
config/profile/swang.config:CONFIG_TOOLCHAIN="freescale-powerpc-linux-gnu-4.1-69.i686.rpm"
config/platform/imx/imx25_3stack.cf:CONFIG_TOOLCHAIN="gcc-4.4.4-glibc-2.11.1-multilib-1.0-1.i386.rpm"
config/platform/imx/imx31ads.cf:CONFIG_TOOLCHAIN="gcc-4.4.4-glibc-2.11.1-multilib-1.0-1.i386.rpm"
config/platform/imx/imx35_updater.cf:CONFIG_TOOLCHAIN="gcc-4.4.4-glibc-2.11.1-multilib-1.0-1.i386.rpm"
config/platform/imx/imx31_3stack.cf:CONFIG_TOOLCHAIN="gcc-4.4.4-glibc-2.11.1-multilib-1.0-1.i386.rpm"
config/platform/imx/imx28_updater.cf:CONFIG_TOOLCHAIN="gcc-4.4.4-glibc-2.11.1-multilib-1.0-1.i386.rpm"
config/platform/imx/imx51.cf:CONFIG_TOOLCHAIN="gcc-4.4.4-glibc-2.11.1-multilib-1.0-1.i386.rpm"
config/platform/imx/imx27ads.cf:CONFIG_TOOLCHAIN="gcc-4.4.4-glibc-2.11.1-multilib-1.0-1.i386.rpm"
config/platform/imx/imx51_3stack.cf:CONFIG_TOOLCHAIN="gcc-4.4.4-glibc-2.11.1-multilib-1.0-1.i386.rpm"
config/platform/imx/imx35_3stack.cf:CONFIG_TOOLCHAIN="gcc-4.4.4-glibc-2.11.1-multilib-1.0-1.i386.rpm"
config/platform/imx/imx6q.cf:CONFIG_TOOLCHAIN="gcc-4.4.4-glibc-2.11.1-multilib-1.0-1.i386.rpm"
config/platform/imx/imx233.cf:CONFIG_TOOLCHAIN="gcc-4.4.4-glibc-2.11.1-multilib-1.0-1.i386.rpm"
config/platform/imx/imx51_updater.cf:CONFIG_TOOLCHAIN="gcc-4.4.4-glibc-2.11.1-multilib-1.0-1.i386.rpm"
config/platform/imx/imx37_3stack.cf:CONFIG_TOOLCHAIN="gcc-4.4.4-glibc-2.11.1-multilib-1.0-1.i386.rpm"
config/platform/imx/imx28.cf:CONFIG_TOOLCHAIN="gcc-4.4.4-glibc-2.11.1-multilib-1.0-1.i386.rpm"
config/platform/imx/imx25_updater.cf:CONFIG_TOOLCHAIN="gcc-4.4.4-glibc-2.11.1-multilib-1.0-1.i386.rpm"
config/platform/imx/imx233_updater.cf:CONFIG_TOOLCHAIN="gcc-4.4.4-glibc-2.11.1-multilib-1.0-1.i386.rpm"

2) In the CVS tree the ../config/platform/imx/.config file I see:
#
# Toolchain selection.
#
CONFIG_TOOLCHAIN_ARMEABI_GLIBC1=y
# CONFIG_TOOLCHAIN_ARMEABI_CUSTOM is not set
CONFIG_TOOLCHAIN="tc-fsl-x86lnx-armeabi-nptl-4.1.2-3.i386.rpm"
CONFIG_TOOLCHAIN_PATH="/opt/freescale/usr/local/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi"
CONFIG_TOOLCHAIN_PREFIX="arm-none-linux-gnueabi-"
CONFIG_TOOLCHAIN_CFLAGS="-O2 -fsigned-char -mfloat-abi=softfp -mfpu=vfp"

So there is definitely a difference.  To reconcile, should I change the BSP 
tree *.cf files to reflect the path 
/opt/freescale/usr/local/gcc-4.1.2-glibc-2.5-nptl-3?  This is what is actually 
in the /opt tree.  Or, do I need to change the versions of gcc I have installed?

Thanks,
Rich



======================
Hi Richard,

My guess is that the cross compiler you're using is not the one needed
to build this compiler.  Can you compare the CONFIG_TOOLCHAIN entries in
the Freescale supplied BSP in the platform preconfig file:
config/platform/_target_/defconfig against the
config/platform/_target_/.config file that your BSP project will have
generated.

Regards, Stuart
