ERROR: Layer meta-gcp-iot is not compatible with the core layer which only supports these series: thud (layer is compatible with rocko master sumo)
So modified the conf file for meta-gcp-iot to include thud.
And then I got this error:
ERROR: /home/nima/wip/mender-atmel/sources/community/tutorials/cloud-iot-mender-ota/image/meta-gcp-iot/recipes-gcp/images/gcp-mender-demo-image.bb: MENDER_DATA_PART_DIR is deprecated. Please use recipes to add files directly to /data instead.
ERROR: Failed to parse recipe: /home/nima/wip/mender-atmel/sources/community/tutorials/cloud-iot-mender-ota/image/meta-gcp-iot/recipes-gcp/images/gcp-mender-demo-image.bb
Can you provide some guidance on steps to proceed to correct this error? I attempted the suggested options based on your documentation but the build did not contain the mender.conf files among others in /data partition.
Thank you
content of modified script used for mender-gcp-build.sh:
Can you please share the changes you did to get around this? There are a couple of locations which use the “old method” to install to /data and all of them need to be updated.
That said, this was only on rocko, and might require some additional updates to work on thud

do_deploy() {
install -d ${DEPLOYDIR}/persist
install -m 0644 persistent.txt ${DEPLOYDIR}/persist
}
addtask do_deploy after do_compile before do_build
Unfortunately the first time I did not document all of my steps as well as this time. So there maybe a few things that are missing from that run. However, I got to a good compile and after I burned an sd image, I saw that the ln file in etc/mender was correctly pointing to /data/mender but did not see an mender.conf in the corresponding /data/mender directory.
I have made the change above and it is now compiling again. I will confirm if I see the same problem. If you already see an issue with what I have done then please let me know as it will take a few hours to compile.
Thank you.
I understood that MENDER_DATA_PART_DIR was used to add files to the data partition of mender.
In examining source of what is building the mender conf file it seems like it is mender-gcp-iot.inc:

Are you suggesting to keep this file intact and just focus on the changing where this statement MENDER_DATA_PART_DIR = “${DEPLOY_DIR_IMAGE}/persist” was placed with your version?
Or should I also make similar changes to the mender-gcp-iot.inc file?
Normally I would experiment more on my own but it takes so many hours to just get a good compile that I rather ask a bit ahead of my next compile.
I have incorporated the changes as specified. That is very helpful. I am not very clear on the mixed-use of ${D} in old code but have not had a chance to find documentation or examine the source code.
It is still not compiling but the problem is with YOCTO at this point. I have been seeking suggestions on the Yocto IRC but thought I would post it here too in case you have a suggestion.
I am getting:

I tried adding -fPIC in a few places but did not get anywhere.
in bitbake.conf under …/poky/meta/conf/bitbake.conf:
TUNE_LDARGS += " -fPIC"
In …/poky/meta/recipes-devtools/perl/perl_5.4.4.bb:
# LDFLAGS for shared libraries
export LDDLFLAGS = "${LDFLAGS} -shared -fPIC"
CFLAGS += "-DDEBIAN -fPIC" # and tried this too!
in ./poky/meta/recipes-devtools/perl/perl-native_5.24.4.bb:
inherit native
##CC += " -fPIC" -- tried this too
export LD="${CCLD} -fPIC"
I can see the -fPIC in gcc statement but looks like I have to add it somewhere else. That is why I tried upstream but that did not work either.
