[Buildroot] [PATCH] Add support for custom post-build script

[Buildroot] [PATCH] Add support for custom post-build script

[nfrench at xtale.biz]

I am currently building my app using the tools in staging_dir to
build my app then I mount the built ext2 from binaries cp my program on
and build a new ext2

Is there a standard why to do this .ie
this custom post-build

would it be possible to document how to
add a simple Hello World app.? So that it gets built? with
buildroot or have I missed somthing in the docs.

Thanks

Nick

This is exactly what I want to avoid. I know it is possible, but using
the post-build script method is faster, more logic and more straight
forward.

Well, it's up to you what you do with that script. You'll be fed with
the target rootfs as $1 and could then do something like

	cp /path/to/your/hello $1/usr/bin/

Or remove unwanted files etc. Up to you.

No, don't confuse that. Your application will not be built by buildroot
by the post-build script.

If you want to do that, you need to add your own package. See the
package/ folder how others do that. And if that package is building a
publically available project, please consider sending a patch back to
this list so everybody can benefit from it.

Thanks Daniel

It would be nice to have a proto type package aka
hello world for us first timers. As for me being able to build for two
different platforms 32bit / 64bit is great feature of buildroot. At the
moment we have been using lfs for 32 bit and 64 bit. Does a package have
to have a network location for download as my prototype code / initial
program ideas go through many revisions before they even get to that stage
:-).

I second the prototype example of a simple helloworld package.

The config help text says it all:

  Specify a script to be run after the build has finished and before
  the BR2 starts packing the files into selected packages.

  This gives users the oportunity to do board-specific cleanups,
  add-ons and the like, so the generated files can be used directly
  without further processing.

  The script is called with the target directory name as first and
  only argument. Make sure the exit code of that script is 0,
  otherwise make will stop after calling it.

Code seems fine by me. It will be useful for some people.

I have normally done this by simply running make twice - E.G. build
the rootfs, fixup anything you need under project_build_*/*/root and
run make again to regenerate the rootfs.

But ok, I can see the desire for such a script. I'll apply it now,
thanks.

It would be good to have a note about it in the documentation - Could
I get you to add a short note about it in docs/buildroot.html?

I think '.. than working around it with a cleanup script.' sounds a
bit better - OK with you?
