我正在尝试在我的Yocto版本上添加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
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。我继续修改我的本地.conf文件，如下所示：
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 = "

ABORT,${DL_DIR},100M,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"
但是我收到此错误：

任何帮助，不胜感激。
编辑：在这里更新了问题。
供您参考，您需要做大量工作才能将 Java 放入映像中。
您当前的映像没有安装任何与 java 相关的程序，因为我在您的编译过程中看不到meta-java。
CORE_IMAGE_EXTRA_INSTALL仅限于 OE 核心映像;因此，如果您有自己的图像配方，除非您继承core-image.bbclass否则该变量将不起作用
下面是将"openjdk-7-jre"放入图像的示例：http://wiki.hioproject.org/index.php?title=OpenHAB:_WeMo_Switch
关键元素是：meta-java，meta-oracle-java。您需要将它们添加到您的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 "
