How do I write a yocto/bitbake recipe to copy a directory to the target root file system

I have a directory of 'binary' (i.e. not to be compiled) files and just want them to be installed onto my target root file system.

I have looked at several articles, none of which seem to work for me.

The desired functionality of this recipe is:

myRecipe/myFiles/ --> myRootFs/dir/to/install

My current attempt is:

SRC_URI += "file://myDir"

do_install() {
         install -d ${D}/path/to/dir/on/fs
         install -m ${WORKDIR}/myDir ${D}/path/to/dir/on/fs
}

I can't complain about the Yocto documentation overall, it's really good! Just can't find an example of something like this!

You just have to copy these files into your target rootfs. Do not forget to pakage them if they are not installed in standard locations.

SRC_URI += "file://myDir"

do_install() {
    install -d ${D}/path/to/dir/on/fs
    cp -r ${WORKDIR}/myDir ${D}/path/to/dir/on/fs
}
FILES_${PN} += "/path/to/dir/on/fs"

How do I write a yocto/bitbake recipe to copy a directory to the targe , I have a directory of 'binary' (i.e. not to be compiled) files and just want them to be installed onto my target root file system. I have looked at several articles, none  Append files, which are files that have the .bbappend file extension, extend or override information in an existing recipe file. BitBake expects every append file to have a corresponding recipe file. Furthermore, the append file and corresponding recipe file must use the same root filename.

Take care that with a simple recursive copy, you will end up having host contamination warnings so you would need to copy with the following parameters:

do_install() {
     [...]
     cp --preserve=mode,timestamps -R ${S}${anydir}/Data/* ${D}${anyotherdir}/Data
     [...]
}

As other recipes in poky do, or just follow the official recommendations to avoid problems with ownership and permissions.

Building your own recipes from first principles, Obtain the required packages for your host system to support Yocto way to cross-compile projects for different targets within Yocto is to make use of autotools you will have a number of new files in the root of the build folder. The recipe will then be picked up by bitbake and you can build the recipe with A BitBake append file uses the .bbappend file type suffix, while the corresponding recipe to which Metadata is being appended uses the .bb file type suffix. You can use a .bbappend file in your layer to make additions or changes to the content of another layer’s recipe without having to copy the other layer’s recipe into your layer.

For a recipe folder like this:

.
├── files
│   ├── a.txt
│   ├── b.c
│   └── Makefile
└── myrecipe.bb

You can use the following recipe to install it on a specific folder into your rootfs:

SRC_URI = " file://*"
do_install() {
    install -d ${WORKDIR}/my/dir/on/rootfs
    install -m 0755 ${S}/* ${WORKDIR}/my/dir/on/rootfs/*
}
FILES_${PN} = "/my/dir/on/rootfs/* "

I think it did not work for you becuase you forgot to add mode value, after "install -m",

see man page of install command: https://linux.die.net/man/1/install

You can copy files from your working directory to any directory in the target filesystem. See the hello-world example for instance (note that the example is taken from the 1.1 reference manual, but I haven't found it yet in the newer

Much simpler to use, top of which custom and specific layers are added, depending on your target. All local files found in SRC_URI are copied into the recipe's working directory, in. Other SDKs often use a custom script for setting up the build environment for yocto (mostly refers on oe-init-build-env from yocto anyway).. I took an excerpt of the setup script from the Freescale SDK 1.9 (fsl-setup-env) and created a script to display the images.

Before doing that I tried creating a separate reciepe and compile c code

  • For a good example of this see psplash_git.bb -> do_install_append
  • Modify this line "install -m ${WORKDIR}/myDir ${D}/path/to/dir/on/fs" to "install -m ${WORKDIR}/myDir/* ${D}/path/to/dir/on/fs"
  • Possible duplicate of How to install recursively my directories and files in BitBake recipe
  • This seems to copy the directory, but none of the files or other directories within it. I'm assuming I have to state all of these explicitly then. Is there a sensible, quick way to do this?
  • Of course it does. It's why I used cp -r for recursive copy.
  • I used cp -r, it copies the 'myDir' directory to the FS but none of its contents...
  • Ok. Try cp -r ${WORKDIR}/myDir/* ${D}/path/to/dir/on/fs. It is strange. I'll have a look. Are you sure myDir is not empty ?
  • What are the differences between using cp and install -m as other users suggested?
  • I just added a direct link to documentation. My advice is to use always install, except when you need some recursive copying.
  • This is pretty much the only correct answer, the thread itself being a dupe of this
