使用BitBake SRC_URI file://获取器去除解压源码树的基础路径

Let me break down what's going wrong here and how to fix it:

The Problem with Your Current Configuration #

When you use file:///src/someproject in SRC_URI, Yocto creates a temporary tarball of the entire someproject directory (not just its contents). The paths inside this tarball look like someproject/file1, someproject/subdir/, etc.

Your original basepath=/src/someproject is trying to match an absolute filesystem path, but basepath works against the paths inside the source archive—not your local system's absolute paths. Since the archive doesn't have a /src/someproject prefix, the basepath rule does nothing, and Yocto extracts the full someproject directory into your source subdir, resulting in the nested structure you're seeing.

Solution 1: Correct the basepath Value #

Use the directory name (not the full absolute path) as your basepath. This tells Yocto to strip that prefix from the archive paths:

SRC_URI="file:///src/someproject;subdir=source;basepath=someproject"

Now when Yocto extracts the archive, it will remove the someproject prefix and drop all files/subdirs directly into build/tmp/work/target/someproject/1.0-r1/source/.

Solution 2: Target Directory Contents Directly #

Alternatively, you can skip basepath entirely by pointing SRC_URI to all contents inside your local directory using a wildcard:

SRC_URI="file:///src/someproject/*;subdir=source"

This tells Yocto to grab every file and subdirectory under /src/someproject and copy them directly into your source subdir, no extra nested directories included.

Either approach will give you the flat source structure you're expecting.
