由于我是 yocto 的新手，我一直在尝试使用简单的 C 程序制作一个配方，该程序使用 makefile 生成二进制文件。创建食谱后，我收到以下错误

我犯了什么错误？
发生错误是因为 makefile 中有
CC = gcchostCROSS_COMPILERhello_shellaarch64-poky-linux-objcopy尝试从 makefile 中删除
CC = gcc您可能需要在 .bbappend 中执行以下操作：
inherit externalsrc
inherit autotools
EXTRA_OEMAKE = 'CROSS_COMPILE=${TARGET_PREFIX} CC="${TARGET_PREFIX}gcc ${TOOLCHAIN_OPTIONS}" V=1'
EXTRA_OEMAKE += ' HOSTCC="${BUILD_CC}'
