Java 在Yocto build上安装libc6-i386

我正在尝试在我的Yocto构建中添加Java安装。我想在我的嵌入式系统上运行我开发的Java应用程序，但我无法正确安装Java。 当我尝试运行java时，我得到以下结果：

./java: No such file or directory

MACHINE ??= "intel-corei7-64"

require conf/multilib.conf
MULTILIBS = "multilib:lib32"
DEFAULTTUNE_virtclass-multilib-lib32 = "x86"

DISTRO ?= "poky"
PACKAGE_CLASSES ?= "package_rpm"
SDKMACHINE ?= "x86_64"
EXTRA_IMAGE_FEATURES ?= "debug-tweaks"
USER_CLASSES ?= "buildstats image-mklibs image-prelink"
PATCHRESOLVE = "noop"
BB_DISKMON_DIRS = "\
    STOPTASKS,${TMPDIR},1G,100K \
    STOPTASKS,${DL_DIR},1G,100K \
    STOPTASKS,${SSTATE_DIR},1G,100K \
    STOPTASKS,/tmp,100M,100K \
    ABORT,${TMPDIR},100M,1K \
    ABORT,${DL_DIR},100M,1K \
    ABORT,${SSTATE_DIR},100M,1K \
    ABORT,/tmp,10M,1K"

PACKAGECONFIG_append_pn-qemu-native = " sdl"
PACKAGECONFIG_append_pn-nativesdk-qemu = " sdl"

CONF_VERSION = "1"

CORE_IMAGE_EXTRA_INSTALL = " lib32-glibc"

CORE_IMAGE_EXTRA_INSTALL += "opencv opencv-samples libopencv-core-dev libopencv-highgui-dev libopencv-imgproc-dev libopencv-objdetect-dev libopencv-ml-dev"

我在谷歌上搜索了一个解决方案，发现我需要安装libc6 32位版本。 我继续修改我的local.conf文件，如下所示：

./java: No such file or directory

MACHINE ??= "intel-corei7-64"

require conf/multilib.conf
MULTILIBS = "multilib:lib32"
DEFAULTTUNE_virtclass-multilib-lib32 = "x86"

DISTRO ?= "poky"
PACKAGE_CLASSES ?= "package_rpm"
SDKMACHINE ?= "x86_64"
EXTRA_IMAGE_FEATURES ?= "debug-tweaks"
USER_CLASSES ?= "buildstats image-mklibs image-prelink"
PATCHRESOLVE = "noop"
BB_DISKMON_DIRS = "\
    STOPTASKS,${TMPDIR},1G,100K \
    STOPTASKS,${DL_DIR},1G,100K \
    STOPTASKS,${SSTATE_DIR},1G,100K \
    STOPTASKS,/tmp,100M,100K \
    ABORT,${TMPDIR},100M,1K \
    ABORT,${DL_DIR},100M,1K \
    ABORT,${SSTATE_DIR},100M,1K \
    ABORT,/tmp,10M,1K"

PACKAGECONFIG_append_pn-qemu-native = " sdl"
PACKAGECONFIG_append_pn-nativesdk-qemu = " sdl"

CONF_VERSION = "1"

CORE_IMAGE_EXTRA_INSTALL = " lib32-glibc"

CORE_IMAGE_EXTRA_INSTALL += "opencv opencv-samples libopencv-core-dev libopencv-highgui-dev libopencv-imgproc-dev libopencv-objdetect-dev libopencv-ml-dev"

但我得到了这个错误：

编辑：更新的问题。

关于您的信息，您需要做大量的工作来将Java放入您的图像中

您当前的映像没有安装任何与java相关的程序，因为我在编译过程中没有看到

MetaJava

CORE\u IMAGE\u EXTRA\u安装

仅限于：；因此，如果您有自己的图像配方，除非您继承

core image.bbclass

下面是一个将“openjdk-7-jre”放入映像的示例：

关键要素是：。 您需要将它们添加到

conf/bblayers.conf

BBLAYERS = " \
 ${BSPDIR}/sources/meta-java \
 ${BSPDIR}/sources/meta-oracle-java \
"

在

conf/local.conf

中，添加此行以安装openjdk-7-jre

IMAGE_INSTALL_append = " openjdk-7-jre "

，这样我就不需要安装32位版本的libc6？好的。我仍然无法让它工作，我打开了一个新问题，因为这个问题已经得到了回答。正如Charles C所回答的，我似乎不需要安装libc6 lib。但我仍然无法让我的构建正常工作。将在将来发布更多信息。
