Yocto 填充sdk命令can'；我不满足我知道存在的nativesdk软件包

我有一个生成-native和nativesdk-packages的配方，但当我尝试填充SDK时，会收到以下错误消息：

~/myproj/build$ bitbake -c populate_sdk core-image-minimal
... lots of error messages ...
Collected errors:
 * opkg_prepare_url_for_install: Couldn't find anything to satisfy 'nativesdk-myapp'.

但是，我在构建该包时没有遇到任何问题：

~/myproj/build$ bitbake myapp myapp-native nativesdk-myapp

该配方使用

BBCLASSEXTEND

添加额外的包。这非常简单：只是一个标准的cmake配方，它更改了两个配置参数，从而从本机和nativesdk构建中省略了单元测试：

inherit cmake

SUMMARY = "My Application"
SRC_URI = "git://git@bitbucket.mydomain.com/project/myapp"
S = "${WORKDIR}/git/"

DEPENDS += "gnutls protobuf protobuf-native dlt-daemon"
DEPENDS_append_class-target = " gtest"

EXTRA_OECMAKE_append_class-native = " -DAPP_FEATURE_TEST=Off"
EXTRA_OECMAKE_append_class-nativesdk = " -DAPP_FEATURE_TEST=Off"

BBCLASSEXTEND = "native nativesdk"

最后，我的发行版文件中有以下几行：

TOOLCHAIN_TARGET_TASK_append += " myapp-dev nativesdk-myapp"

---

我可以很好地构建nativesdk myapp包，但由于某些原因，populate_sdk目标无法找到它。

问题出在发行版文件中。应该是这样的：

TOOLCHAIN_TARGET_TASK_append += " myapp-dev"

TOOLCHAIN_HOST_TASK_append += " nativesdk-myapp"

TOOLCHAIN\u TARGET\u TASK

是进入目标sysroot的SDK包，在本例中，目标sysroot是Jacinto SoC上的ARM

TOOLCHAIN\u HOST\u TASK

是进入主机系统根目录（即x86\u 64）的SDK包

Yocto非常明智地抱怨它没有针对ARM/Jacinto的nativesdk myapp包
