Build OE with meta-swupdate layer

[peter.j...@gmail.com]

Hi,
I try to compile OpenEmbedded image with meta-swupdate layer for Toradex iMX7s board. I got some errors in compilation and don't know how to fix it. Maybe someone can help me.

I am using Angstrom 2.7b5 distribution provided by Toradex. This version is based on YOCTO "morty". So, I downloaded "morty" branch of meta-swupdate from GIT. But there is a conflict between two provided versions of u-boot-fw-utils in project:

ERROR: Multiple .bb files are due to be built which each provide u-boot-fw-utils:
/home/cominfo/oe-core/build/../layers/meta-toradex-nxp/recipes-bsp/u-boot/u-boot-toradex-fsl-fw-utils_git.bb
/home/cominfo/oe-core/build/../layers/openembedded-core/meta/recipes-bsp/u-boot/u-boot-fw-utils_2016.03.bb

Toradex u-boot version is newer - 2016.11, so I added following line into local.conf:

PREFERRED_PROVIDER_u-boot-fw-utils = "u-boot-toradex-fsl-fw-utils"

But now I got this error:

ERROR: swupdate-2017.01-r0 do_compile: oe_runmake failed
ERROR: swupdate-2017.01-r0 do_compile: Function failed: do_compile (log file is located at /home/cominfo/oe-core/build/tmp-glibc/work/armv7at2hf-neon-angstrom-linux-gnueabi/swupdate/2017.01-r0/temp/log.do_compile.6246)

In the log file is this:

/home/cominfo/oe-core/build/tmp-glibc/sysroots/x86_64-linux/usr/libexec/arm-angstrom-linux-gnueabi/gcc/arm-angstrom-linux-gnueabi/6.2.1/ld: error: cannot find -lubootenv

collect2: error: ld returned 1 exit status
Makefile:372: recipe for target 'swupdate_unstripped' failed

If I add this into local.conf to use 2016.03 version:

PREFERRED_PROVIDER_u-boot-fw-utils = "u-boot-fw-utils"

Then I got this error again:

ERROR: Multiple .bb files are due to be built which each provide u-boot-fw-utils:
/home/cominfo/oe-core/build/../layers/meta-toradex-nxp/recipes-bsp/u-boot/u-boot-toradex-fsl-fw-utils_git.bb
/home/cominfo/oe-core/build/../layers/openembedded-core/meta/recipes-bsp/u-boot/u-boot-fw-utils_2016.03.bb

If I use "master" branch of meta-swupdate instead of "morty", then I got this error:

Hi Peter,

Sorry, the issue with libubootenv was already treated. You have to fix
in verndor's BSP the building of libubootenv.a. This is the reason why
linking for SWUpdate fails. As reported in documentation, you should not
use any version less that 2016.05. 2016.03 does not work even if you
link (you should then fix yourself).

If you replace package's names with something else you find funny,
things go from bad to worse. u-boot-toradex-fsl-fw-utils is not the
official package name in Yocto (u-boot-fw-utils is) and
u-boot-fw-utils%.bbappend in meta-swupdate cannot be applied: the
installation of libubootenv.a is skipped.

Best regards,
Stefano Babic
