[yocto] Build error while following Appendix A. Yocto Project Development manual

Tue Nov 1 17:45:38 PDT 2011

Hi James,

I'm still not sure what happened in your case to cause this problem, but
I just went through the Appendix A example pretty much as described, and
got a good build out of it.  There was one particular part of the
example that wasn't exactly clear and that could definitely cause some
build problems if you did it incorrectly (the section that makes changes
to linux-yocto_3.0.bbappend, which in the example has a custom branch in
the .bbappend file, but has the explanation using atom-pc).

I'll work with Scott to make sure that part gets cleaned up, along with
the other comments that should get pulled in, but in the meantime, I
captured the steps I used below, which should work in the same way for
you.

trz at elmorro:/usr/local/dev/yocto$ mkdir bsp-test; cd bsp-test
trz at elmorro:/usr/local/dev/yocto/bsp-test$ git clone git://git.yoctoproject.org/poky
trz at elmorro:/usr/local/dev/yocto/bsp-test$ cd poky
trz at elmorro:/usr/local/dev/yocto/bsp-test/poky$ git checkout -b edison origin/edison
trz at elmorro:/usr/local/dev/yocto/bsp-test/poky$ git clone git://git.yoctoproject.org/meta-intel.git
trz at elmorro:/usr/local/dev/yocto/bsp-test/poky$ cd meta-intel
trz at elmorro:/usr/local/dev/yocto/bsp-test/poky/meta-intel$ git checkout -b edison origin/edison
trz at elmorro:/usr/local/dev/yocto/bsp-test/poky/meta-intel$ cp -a meta-crownbay/ meta-mymachine
trz at elmorro:/usr/local/dev/yocto/bsp-test/poky/meta-intel$ rm meta-mymachine/conf/machine/crownbay.conf
trz at elmorro:/usr/local/dev/yocto/bsp-test/poky/meta-intel$ mv meta-mymachine/conf/machine/crownbay-noemgd.conf meta-mymachine/conf/machine/mymachine.conf
trz at elmorro:/usr/local/dev/yocto/bsp-test/poky/meta-intel$ rm -rf meta-mymachine/recipes-bsp/formfactor/formfactor/crownbay/
trz at elmorro:/usr/local/dev/yocto/bsp-test/poky/meta-intel$ mv meta-mymachine/recipes-bsp/formfactor/formfactor/crownbay-noemgd meta-mymachine/recipes-bsp/formfactor/formfactor/mymachine

----
The Developer's Manual seems to want to base the BSP on atom-pc for
this example, so we need to specify the atom-pc branch and get the
SRCREVs for atom-pc or the step that modifies the
linux-yocto_3.0.bbappend.  So in
meta-yocto/recipes-kernel/linux/linux-yocto_3.0.bbappend, we find both
the KMACHINE branch we need, and the SRCREV on that branch we need for
edison.  Since that doesn't specify the meta branch, but the base
recipe does, we can look at the SRCREV_meta there
(meta/recipes-kernel/linux/linux-yocto_3.0.bb) for the SRCREV of the
meta branch, which already matches what we're using, so no change
needed there.

Here's the resulting linux-yocto_3.0.bbappend:

trz at elmorro:/usr/local/dev/yocto/bsp-test/poky/meta-intel$ cat meta-mymachine/recipes-kernel/linux/linux-yocto_3.0.bbappend

FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"

COMPATIBLE_MACHINE_mymachine = "mymachine"
KMACHINE_mymachine  = "yocto/standard/common-pc/atom-pc"
KERNEL_FEATURES_append_mymachine += " cfg/smp.scc"

SRCREV_machine_pn-linux-yocto_mymachine ?= "1e18e44adbe79b846e382370eb29bc4b8cd5a1a0"
SRCREV_meta_pn-linux-yocto_mymachine ?= "d05450e4aef02c1b7137398ab3a9f8f96da74f52"
