Yocto: Adding glibc libraries to the rootfs

Question

I am building binaries for our custom board(iMX7) using Yocto-morty. I need some libraries such as UTF-32.so, UTF-16.so, UTF-7.so from glibc package for bluetooth file tranfer. But these libraries are not available in the rootfs, only files available under /usr/lib/gconv are gconv-modules and ISO8859-1.so. So I am trying to add these libraries by adding new bbappend file glibc_2.24.bbappend with the following content

FILES_${PN} += "${libdir}/gconv/*"

do_install_locale_append() {
cp -r ${dest}${libdir}/gconv ${D}${libdir}/
}

But it results in the following error:

ERROR: glibc-2.24-r0 do_populate_sysroot: The recipe glibc is trying to install files into a shared area when those files already exist. Those files and their manifest location are:

build_dir/tmp/sysroots/esomimx7d/usr/lib/gconv/ISO-2022-CN.so  Matched in b'manifest-esomimx7d-glibc-locale.populate_sysroot'

build_dir/tmp/sysroots/esomimx7d/usr/lib/gconv/ARMSCII-8.so Matched in b'manifest-esomimx7d-glibc-locale.populate_sysroot'

......

Then I tried to remove the glibc-locale from the image but due to some dependency issues I could not do that.

Could anyone help me to add the above mentioned libraries to the rootfs?

The error is telling you the answer to your problem. Those files are part of the glibc-locale recipe, so you just need to install the right packages into the rootfs.

$ oe-pkgdata-util find-path \*/UTF-7.so
glibc-gconv-utf-7: /usr/lib/gconv/UTF-7.so

So you need to add glibc-gconv-utf-7 (or -utf-32, etc) to your image.
