[yocto] Adding a shared object file to rootfs

[Sathish Kumar Balasubramaniam -ERS, HCL Tech]

Thanks, Robert Yang.

Method using abc.bb:
~~~~~~~~~~~~~~~~

Before I tried using abc.bb, but I faced an error that says unknown package abc and something like opkg_install_cmd: cannot install .....
Hence I thought of trying linux-kernel_3.4.bbappend.

But now I added like the following to the abc.bb file (before I didn't give the -dbg line)

FILES_${PN} += "${base_libdir}"
FILES_${PN}-dbg += "${base_libdir}/.debug"
FILES_SOLIBSDEV = ""

Now it's working :)   --------> This is fine for me and as you said, this is the recommended way too.

Method using linux-kernel_3.4.bb just for analysis :
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I tried to add FILES_kernel-vmlinux like the following

do_install_append () {
        install -d ${D}${base_libdir}
        install -m 0644 ${WORKDIR}/abc.so ${D}${base_libdir}
}

FILES_kernel-vmlinux += "${base_libdir}"
FILES_kernel-vmlinux-dbg += "${base_libdir}/.debug"

I am getting the following error

ERROR: QA Issue: non debug package contains .debug directory: kernel-vmlinux path /work/<machine>-poky-linux-gnueabi/linux-yocto/3.4+<version>/packages-split/kernel-vmlinux/lib/.debug/abc.so

Hello,

I think that there are two problems:

1) You can use a abc.bb to add the abc.so rather than .bbappend, then you can
    add something like:
    IMAGE_INSTALL_append = "abc"

    to conf/local.conf.

2) Please see my comments inline.

The linux-yocto_3.4.bb doesn't generate a linux-yocto.rpm since linux-yocto
(the ${PN}) doesn't in PACKAGES, you can use bitbake -e linux-yocto to
see this, and if you really want to use linux-yocto_3.4.bbappend,
you can use (WARN: this is highly suggested NOT)

FILES_kernel-vmlinux += "${base_libdir}/abc.so"

Then maybe you would get the warning about unshipped  /lib/.debug
and /lib/.debug/abc.so, you need add them to kernel-vmlinux-dgb. Again,
this is highly suggested not, The suggested way is abc.bb.
