[Buildroot] Adding custom config files to a package

[Buildroot] Adding custom config files to a package

[Aleksandar Simeonov]

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

  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.

  make clean; make

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

  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.
