Additional layers with class and conf

Additional layers with class and conf

[Woronicz, Bartosz ( NSN - PL/Wroclaw)]

I got two layers, meta-x and meta-y , meta-x got meta-y in 
bblayers.conf.   in meta-y contains conf/layer.conf with BBPATH .= 
":${LAYERDIR}", plus classes/my.bbclass plus local.conf containing 
INHERIT += "my"
when I ran bitbake -e my-image, the INHERIT doesn't seem to contain "my"

When I put it directly in layer.conf it works, but what to add to 
layer.conf to make bitbake to look for other *.conf files in meta-y/conf/ ??

My bblayers.conf.sample is modified in meta-x (the project meta), which 
is copied over to $BUILDDIR when i run oe-init-build-env ,
here is meta-y/conf/layer.conf  :  http://pastebin.com/mhxe9K5C

when I ran
bitbake -e my-image
i see
BBPATH="/var/fpwork/mastier/myproject/poky/meta-yocto:/var/fpwork/mastier/myproject/mymachine:/var/fpwork/mastier/myproject/poky/meta:/var/fpwork/mastier/myproject/poky/meta-yocto-bsp:/var/fpwork/mastier/myproject/meta-x:/var/fpwork/mastier/myproject/meta-y"

where "mymachine" is my BUILDDIR

HI,

Have you checked full output of -e bitbake run ? Were INHERIT variable is
resolved ? To check if *.conf file was checked ? Maybe some confs change
INHERIT variables during parsing.

Do you mean you put local.conf in a conf subdirectory of a layer? If so,
that's not really expected to work.

You don't, at least not in that way. The correct way to do things like this is
to create a custom distro and then set DISTRO to point to it. Your distro conf 
file can then set these kinds of things.

That's a good point, I took a look at it. But for now I rather rely on poky distro. Later, possibly I will put my classes in INHERIT to mydistro.conf.

Thanks!

Hi,

I thought local.conf is automatically read, but I was wrong. For time being I put ‘ INHERIT += “my” ’ in layer.conf. Later on I will think of my own distro meta.

Maybe I am wrong, but yocto is missing ability to have kind of utility meta layer. But maybe it is just unnecessary bloat.
