I want to be able to change the contents of 'interfaces' in a way that means I
don't have to change the meta/ tree. It looks like layers should do this for me
(section 3.4.1 of the
Poky Reference Manual), but I can't seem to get my files to take precedence.
For example, a default build for laverne-4.0.1 uses
core-recipes/netbase/netbase/qemux86/interfaces.
I've created an empty copy of the meta-emenlow layer, changed its layer.conf as
required and added it in to bblayers.conf. I can tell this is getting picked up
as I get a warning
that it contains no .bb files (it will eventually).
However, my meta-new/packages/netbase/netbase/qemux86/interfaces file isn't
overriding the one above.
What else do I need to do? Do I need to have something other that .bb and
.bbappend added to BBPATH (or something else)?
You'll need a meta-new/packages/netbase/netbase_4.44.bbappend file which
tells bitbake where to find your override files. I do this all the time,
for example, I have a board with two targets:
$ tree meta-ppc/packages/netbase/
meta-ppc/packages/netbase/
├── netbase-4.44
│ ├── cobra
│ │ ├── interfaces
│ └── ppc8379
│ ├── interfaces
└── netbase_4.44.bbappend
$ cat meta-ppc/packages/netbase/netbase_4.44.bbappend
THISDIR := "${@os.path.dirname(bb.data.getVar('FILE', d, True))}"
FILESPATH =. "${@base_set_filespath(["${THISDIR}/${PN}-${PV}"], d)}:"
