Crazy versioning

Crazy versioning

[Gary Thomas]

I'm trying to use the recipe meta/recipes-bsp/u-boot/u-boot_2011.06.bb
Since there are a number of u-boot recipes, I want to make sure I get
the right one, plus I'm writing a .bbappend file to add patches for
my own boards.

So I added this to my MACHINE.conf:
   PREFERRED_VERSION_u-boot = "2011.06"

When I try to build, I get this error:
   NOTE: preferred version 2011.06 of u-boot not available (for item u-boot)
   NOTE: versions of u-boot available: git v2011.06+git16+b1af6f532e0d348b153d5c148369229d24af361a
I guess this is because the recipe has this for PV
   SRCREV = "b1af6f532e0d348b153d5c148369229d24af361a"
   PV = "v2011.06+git${SRCPV}"
The truly bizarre thing is that if my cache is rebuilt, the version printed changes, e.g.
   % touch conf/local.conf
   % bitbake u-boot
   NOTE: versions of u-boot available: git v2011.06+git18+b1af6f532e0d348b153d5c148369229d24af361a

So, how do I specify the right value in PREFERRED_VERSION?

Should just be:

 PREFERRED_VERSION_u-boot = "v2011.06%"

or

   PREFERRED_VERSION_u-boot = "v2011.06+git%"

if you like that format more. I went through the same thing with the kernel
recipes, and the solution is to specify a wildcard via %

Cheers,

Bruce

with % as wildchar

PREFERRED_VERSION_u-boot = "v2011.06%"

You look at the PV value in the recipe and then write something like:

PREFERRED_VERSION_u-boot = "2011.06+git%"

where % is a wildcard that matches the revision.

The reason the version incremented is down to bitbake thinking multiple
versions were being built and trying to keep versions atomically
increasing.

Cheers,

Richard

Thanks, that does work.

I gave a cursory look in the documentation (both Yocto & bitbake) and
I didn't see an explanation of this.  There's a single reference
   ../documentation/bsp-guide/bsp.xml:     PREFERRED_VERSION_linux-yocto = "3.0%"
but nothing that explains it.

FYI I have sent Scott R some additions to the variable reference in the manual 
that will mention the % wildcard and give an example.

Cheers,
