N/AN/ALayer should set LAYERSERIES_COMPAT in its conf/layer.conf file to list the core layer names it is compatible with.Newer version of bitbake throws warning if we don’t set LAYERSERIES_COMPAT in its conf/layer.conf in the respective layers.

Set LAYERSERIES_COMPAT_<layer name> = "dunfell" in all layers.

E.g LAYERSERIES_COMPAT_rdk = "dunfell" for meta-rdk layer.

N/Ameta-rdk-extbb.data_smart.ExpansionError: Failure expanding variable AVAILABLE_LICENSES[:=], expression was ${@' '.join(available_licenses(d))} which triggered exception FileNotFoundError: [Errno 2] No such file or directory.There is no directory called licenses in the corresponding meta layer.Need to create a licenses directory under the meta-layer and add RDK license file to it






Error due to the usage of base_contains in multiple recipes.base_contains is deprecated.use bb.utils.contains instead of deprecated base_contains in the respective recipes.
N/AN/AError due to the usage of some of the functions in pythonnative.bbclass in multiple recipes.pythonnative.bbclass is not available in newer version.Add meta-python2 layer to get support for legacy pyhton code(E.g pythonnative.bbclass)







Error due to the usage of base_conditional in multiple recipes.base_conditional is deprecated.use oe.utils.conditional instead of deprecated base_conditional in the respective recipes.
uclibc.incmeta-rdk-extError due to the usage of oe_filter_out in multiple recipes.oe_filter_out is deprecated.use oe.utils.str_filter_out instead of deprecated oe_filter_out in the respective recipes.

Glib-networking require gnutls >= 3.4.6 gnutls 3.3.x is the last branch which supports.nettle 2.7.1. So it is not possible to increase the version,Used glib-networking-2.54.1 instead of updating gnutls.
gstreamer1.0-plugins-bad.incmeta-rdk-extError while inheriting bluetooth.bbclassbluetooth.bbclass is not available in newer version of yocto

inherit bluetooth on a conditional basis as shown below:

openssl_1.1.0g.bbmeta-rdk-extError while fetching openssl_1.1.0g Recipe version 1.1.0 is moved to a different location. SRC_URI updated with the new changes.
systemd_216.bbmeta-rdk-extError while parsing systemd_216 legacy recipe  Circular dependency problem with systemd_216.

Skip this recipe by specifying the COMPATIBLE_HOST in bb file as shown below:

COMPATIBLE_HOST_dunfell = "null"


meta-cmf-videoError due to invalid version of netsrvmgr.SRCREV expects a valid revision on dunfell framework.SRCREV for netsrvmgr set to AUTOREV
iptables_%.bbappendmeta-rdk-extError while installing iptablessysint provides it's own iptables systemd service file which gives a conflict on do_rootfs()

Remove systemd service in the bbappend file to avoid conflict as shown below:

do_install_append_client() {
rm ${D}${systemd_system_unitdir}/${PN}.service

SYSTEMD_SERVICE_${PN}_remove_client = "${PN}.service"


meta-rdk-extPatch error while building dropbear-2019.78Older version of patches were giving build error.Rebase patches to build on dunfell.

qtbase-native_5.1.1.bbappendmeta-cmf-qt5qtbase-native: fix build error due to gcc 9.xqtbase native pkg throws build error due to gcc 9.2.

The following patch file is available in the repo to resolve the issue:


We need to conditionally enable this for dunfell builds. 

logrotate_%.bbappendmeta-rdk-extSysint trying to install logrotate.service, logrotate.timer but it is already installed by logrotate.as sysint provides logrotate's systemd service, actual recipe's service gives conflict

As sysint installs RDK specific logrotate's systemd service file, we can remove them as shown below:

SYSTEMD_SERVICE_${PN}_remove = " \
${BPN}.service \
${BPN}.timer \

do_install_append() {
rm ${D}${systemd_system_unitdir}/${BPN}.service
rm ${D}${systemd_system_unitdir}/${BPN}.timer

dnsmasq_%.bbappendmeta-rdk-ext Postinstall scriptlets of ['systemd'] failed.As systemd in dunfell provides resolv.conf, no need to install again from dnsmasq.Removed resolv.conf from do_install for dunfell


meta-cmf-qt5Declaration conflict for qopengl's GLdouble because of this qtbase throws build error.GLdouble is typedefed as GLFloat in qopengl.h this leads to a conflict with the earlier definition of GLdouble as double.We can typedef GLdouble to double.
msgpack-c_2.1.1.bbmeta-rdk-extError about 'copying an object of non-trivial type' in msgpack-c.Typecasting is missing while using memcpy().

Insteadof using 

std::memcpy(&o, &v, sizeof(v)), we can typecast the object as shown below

iarmmgrs_git.bbappendmeta-cmf-videopackage_qa error while building iarmmgrs_git.bbhybrid specific runtime deps overriding basic runtime deps which causes package_qa error.

Use append instead of simple assignment for the runtime dependency for iarmmgrs as shown below:

RDEPENDS_${PN}_append_hybrid = " virtual/mfrlib"

cairo_%.bbappendmeta-rdk-extConflict due to patches available in other layers while patching cairo.meta-wpe also maintains cairo patches that makes conflict while apply.
