[yocto] dnf fail in do_rootfs cannot find shared library

[Måns Zigher]

Hi guys,

I found the issue and dnf is doing exactly what it should. The problem is
the shared library

readelf -d libx_media_1.0.so


Dynamic section at offset 0xf31c8 contains 40 entries:
  Tag        Type                         Name/Value
....
...
 0x000000000000000e (SONAME)             Library soname: [
libx_media_1.0_wtf.so]

So the SONAME of the file is actually set to libx_media_1.0_wtf.so but the
file is named libx_media_1.0.so and the executable that is part of the
package is linked against libx_media_1.0.so also.
I manage to figure this out when I was going
through /tmp/work/path/to/xmedia/1.0-r43/pkgdata/shlibs2 and I noticed that
in xmedia.lst file actually did not include the libx_media_1.0.so but
libx_media_1.0_wtf.so.
Thanks for your efforts.
