bitbake recipe for copying folder, subfolders for yocto

问题

I want copy folders and it's content to yocto during image build process. For this process I am using following recipe

SUMMARY = "Installation Recipe"
DESCRIPTION = "It installs folder"
HOMEPAGE = ""
LICENSE = "CLOSED"

MY_FILES1 = "/home/jane/d1fold"
MY_FILES2 = "/home/jane/d2fold"

inherit allarch

do_install() {
    install -d ${D}/home/root
    cp -R ${MY_FILES1}/* ${D}/home/root
    cp -R ${MY_FILES2} ${D}/home/root
}
FILES_${PN} += " /home/root"

But I receive following error ERROR: QA Issue: weaved: Recipe inherits the allarch class, but has packaged architecture-specific binaries [arch]. How can I resolve this error?

回答1:

This error means that you are trying to install architecture-specific binaries (compiled for x86, arm64 etc), while inheriting allarch class. From yocto reference manual:

The allarch class is inherited by recipes that do not produce architecture-specific output.

This is an obvious contradiction.

What are you trying to do? Creating of recipe that only installs some files seems like wrong architecture decision. And why do you want to inherit allarch?

回答2:

You are just coping files to rootfs. So you no need use inherit allarch. remove that and compile.
