我使用从freescale获得的外部预构建二进制工具链，并按照linaro wik中的说明列表进行操作。按照这个指示，我将meta-linaro（主分支）层添加到openembedded / meta层前面的conf / local.conf中，并添加EXTERNAL_TOOLCHAIN和TCMODE GCCVERSION变量如下：
GCCVERSION = "linaro-4.6"
SDKGCCVERSION = "linaro-4.6"
EXTERNAL_TOOLCHAIN = "/extdisk/yocto/88/arm-fsl-linux-gnueabi/4.6.2"
TCMODE = "external-linaro"
IMAGE_LINGUAS = ""
LIMIT_BUILT_LOCALES = "POSIX"
DEFAULTTUNE_qemuarmv7a = "armv7athf-neon"
我的工具版详细信息是：

当我使用bitbake -v core-image-minimal构建图像时，会发生错误：
$ bitbake -v core-image-minimal

我不知道出了什么问题，任何人都可以帮助我吗？
答案 0 :(得分：1)
我收到了类似的消息

事实证明这是导致我出现问题的最后一个错误......我需要安装ncurses libs
您的输出有一行可能是问题
