Hi Alex
I’d like to explain it.
->Why not simply ${D}/etc/rpm?
As you see, ${SDKTARGETSYSROOT} for x86_64 is
/opt/poky/2.7+snapshot/sysroots/core2-64-pokysdk-linux.
I make it because config file in host-sysroot as
/opt/poky/2.7+snapshot/sysroots/x86_64-pokysdk-linux will be covered by
another ARCH.
For example, first install SDK for x86_64, and next install SDK for x86, as
host-sysroot is same, the same config file will be covered. In that case config
settings for x86_64 will be inefficacy.
To resolve that problem, I put config file in target-sysroot like
/opt/poky/2.7+snapshot/sysroots/core2-64-poky-linux. As each ARCH has its own
target-sysroot, config file will not be covered.
That was also why I put config file in meta-environment in last patch.
->What do these two sed commands do? If we create /etc/rpmrc just above, can it
have the right content from the beginning?
Well, in the environment in Yocto Build system, the value of ${PACKAGE_ARCHS}
include “–nativesdk” as not needed in SDK environment.
And the ARCH name of core2-64 rpm is core2_64 like rpm-4.14.2.1-r0.core2_64.rpm.
So I modify the ARCH name in etc/rpmrc.

What do these two sed commands do? If we create /etc/rpmrc just above, can it

"
+FILES_${PN}_append_class-nativesdk += "${SDKTARGETSYSROOT}"
Same question: why is ${SDKTARGETSYSROOT} needed? The configuration files
should be in /etc, and rpm should be instructed to pick them up from there,
same way as it is done for -native variant when building an image.
