Hi Gustavo,

Sorry to disturb you again, but back to our discussion sometime ago on #buildroot IRC channel:

Now I'm trying to implement your idea to use <pkg>_config files to copy some custom configuration target once the main package is built. The idea works great, however it has certain drawbacks - It is executed only the first time you build the main package, and then gets added to the rootfs.jffs image. As soon as I have the image built, any make runs after that do not rut through it, as if it is not detected as a dependency. This is bit of a problem because when rebuilding the image (for this I clean the target folder before that), the make does not copy the <pkg> relevant files to the output/target folder, and thus not propagating them to the image :( Is there anything I can do about it?

I have tried adding a Config.in file, and source it in the main Config.in file in my BR2_EXTERNAL folder, but then the make tries to "compile" it, and fails with "No scheme" message. I assume that do not need to run $(eval $(whatever-package)) at the end because it is not a real package, so commenting it solves the compilation error, but still is not run

Attached I'm sending an example for configuring dropbear package. In my main Config.in file I source this one, and the path to the makefile is included in my external.mk

Could you advise something in this case?

Thank you very much in advance

Alex

Hi Gustavo,

The idea works great, however it has certain drawbacks - It is executed only the first time you build the main package, and then gets added to the rootfs.jffs image. As soon as I have the image built, any make runs after that do not rut through it, as if it is not detected as a dependency.

Indeed, buildroot doesn't really support rebuilding. You can explicitly
rebuild a single package with 'make foo-rebuild', but that doesn't force other packages that depend on it to be rebuilt.

This is intentional, because the result of rebuilding individual packages is
anyway somewhat unpredictable.

This is bit of a problem

make clean; make

I have tried adding a Config.in file, and source it in the main Config.in file in my BR2_EXTERNAL folder, but then the make tries to "compile" it, and fails with "No scheme" message.

Sound like you specified a _SITE with a URL that doesn't start with http://

I assume that do not need to run $(eval
$(whatever-package)) at the end because it is not a real package, so commenting it solves the compilation error, but still is not run

  If you don't have a $(whatever-package) in your .mk file, nothing is done with it.

I think you attached the wrong files, the dropbear_config.mk is missing.

Arnout
