用于追加文件目录的Yocto / Bitbake路径变量

Question

So I am using a .bbappend file in a layer I have created and in that layer I also have some additional local files that I want to install.

The problem is I am not sure what the Yocto variable is that correctly represents the directory where my bbappend file is located. Variables like "THISDIR" end up pointing to the original recipe directory - not the append one in my layer. How can I best do this without putting some type of absolute path?

Answer 1

Copy your files to present dir where the .bb or .bbappend file is present. and add follow line hello.bbappend

FILESEXTRAPATHS_prepend := "${THISDIR}:"    
SRC_URI += "file://yourfile"
do_install_append(){
      install -d ${D}/some-dest-dir
      install -m 0644 ${S}/yourfile ${D}/some-dest-dir/
}

here THIS dir means you are telling to bitbake the files are present in the dir where the .bb or .bbappend file is present.

eg: meta-hellolayer example/
|_ hello.c
|_ hello.bbappend

Now the example dir is THIS dir in .bbappend file.

Note : Make sure you need to add your layer path(meta-helolayer) to build/conf/bblayer.conf
