Question

我是yocto的新手。我创建了一个简单的图层，它包含一个用于wpa_supplicant的简单补丁文件。我想从我自己的图层修改wpa_supplicant.conf-sane文件。原始的wpa_supplicant驻留在不同的层上

wpa-supplicant-bbappend
        ├── wpa-supplicant
        │   └── wiress_info.patch
        └── wpa-supplicant_2.6.bbappend

我已经生成了一个差异文件

 diff -u ../../../poky/meta/recipes-connectivity/wpa-supplicant/wpa-supplicant/wpa_supplicant.conf-sane wpa-supplicant/wpa_supplicant.conf-sane > wpa-supplicant/wiress_info.patch

这是我的补丁文件：

 }

这是我的wpa-supplicant_2.6.bbappend文件

FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"
SRC_URI_append = " file://wiress_info.patch "

在yocto修补过程中仍然出现一些错误

Applying patch wiress_info.patch

Perhaps you used the wrong -p or --strip option?
The text leading up to this was:

我无法弄清楚我在做什么错？请帮助

您的补丁程序有错误的源文件要指定的补丁程序。因此，显示消息“没有要修补的文件。”。

修补程序通过选项-p1（请参阅Patching Code in doc）应用于变量S中的目录（即解压缩的源文件，请参阅Patching in doc）。

尽管您可以通过在striplevel中添加SRC_URI选项来应用该补丁，但是正确的方法是修复补丁本身。请参阅Nayfe关于devshell的评论，这是一种简便的方法（或在diff命令中修复路径）。
