Here it is:

1. Name and path to your mypackage recipe:

    meta-dave/recipes-devtools/testpkg/testpkg_0.1.bb

2. The variables from your mypackage recipe: PN, PROVIDES.

4. The full line IMAGE_INSTALL you've added.
    IMAGE_INSTALL += "testpkg"

P.S. Also, am I right, that you are able to run 'bitbake mypackage' without errors?

As you can see the package and the image can be built fine if the variable IMAGE_INSTALL is left empty. As soon as I add testpkg to the IMAGE_INSTALL variable I get this error:

My understanding is this: The testpkg.deb is generated and placed correctly inside the build/tmp/work/lynx-armhf/testpkg-0.1-r0 but then it seems that it can't be found while the image is being built. How does bitbake know how to install the package? For other pre-compiled packages I used a dedicated recipe which inherits from dpkg class. These packages however, were not being produced at runtime. The situation now is a bit different. I'm trying to build the package and install it on the rootfs at runtime.
Perhaps I'm misunderstanding something, given that my experience with both yocto and isar is quite limited.
Thanks

I tried to add the package name to the IMAGE_INSTALL variable inside my image recipe. This returned an error: Unable to locate package mypackage. I thought that I was doing something wrong, but I guess that if this is the correct way, the problem is somewhere else.

Possibly I could also take a look on this, if you provide:

1. Name and path to your mypackage recipe, like:

meta-isar/recipes-app/libhello/libhello.bb

2. The variables from your mypackage recipe: PN, PROVIDES.

3. The content of your conf/bblayers.conf file.

4. The full line IMAGE_INSTALL you've added.

P.S. Also, am I right, that you are able to run 'bitbake mypackage' without errors?

Hello guys,

I still have a question regarding the management of customised packages.

I managed to create my .deb package using dpkg-raw but I would like also to install it on the rootfs of my image. How can this be done?

Adding the package to IMAGE_INSTALL variable, does not seem to work. Perhaps another recipe is required?

it depends where you've added IMAGE_INSTALL. It should be visible for image recipe, so you have to add it to one of the following places:
1. Into you image recipe. If you use isar-image-base, then update file 'meta-isar/recipes-core/isar-image-base.bb'
2. Edit 'conf/local.conf' file in your build directory and add this line to the end.
