[OE-core] Issue of Yocto multilib sdk

[Kumita Bruce]

Hi experts,

I use Yocto to generate multilib sdk, I append following content in my
local.conf.
    require conf/multilib.conf
    MULTILIBS = "multilib:lib64"
    DEFAULTTUNE_virtclass-multilib-lib64 = "x86-64"

    IMAGE_INSTALL_append = " \
        ${@multilib_pkg_extend(d, "binutils")} \
        ${@multilib_pkg_extend(d, "eglibc")} \
        ${@multilib_pkg_extend(d, "eglibc-dev")} \
        ${@multilib_pkg_extend(d, "eglibc-staticdev")} \
        ${@multilib_pkg_extend(d, "gcc")} \
        ${@multilib_pkg_extend(d, "glib-2.0")} \
        ${@multilib_pkg_extend(d, "glib-2.0-dev")} \
        ${@multilib_pkg_extend(d, "libgcc-dev")} \
        ${@multilib_pkg_extend(d, "libstdc++")} \
        ${@multilib_pkg_extend(d, "libstdc++-dev")} \
        ${@multilib_pkg_extend(d, "libstdc++-staticdev")} \
    "

The sdk is generated successfully, I
installed poky-eglibc-x86_64-i586-toolchain-gmae-1.4+snapshot-20130619.sh
in the default path(/opt/poky/1.4+snapshot/).
1. 32bit build for my test C program, it passed,
    $ source /opt/poky/1.4+snapshot/environment-setup-i586-poky-linux
    $ $CC mytest.c -o mytest.c
2. 64bit build for the same test C program, it failed.
    $

collect2: error: ld returned 1 exit status

Am I missing something?


Cheers,
