I'm building an embedded linux system using Buildroot. Our hardware is identical to Beagle Bone Green development board. When I added ssh, it didn't start printing:

/usr/bin/ssh-keygen: can't load library 'libatomic.so.1'
Starting sshd: /usr/sbin/sshd: can't load library 'libatomic.so.1'

The library itself exists in the directory /usr/lib/. It seems like the system are not able to load any shared library. ldconfig -p prints:

Library cache disabled

What can be the problem?

    It sounds like either libatomic.so or ssh was built with an incompatible toolchain. Did you build everything within buildroot? Did you change the configuration of the toolchain without doing a 'make clean' inbetween? The ldconfig -p output is expected: buildroot doesn't use the library cache, it always searches libraries in /lib and /usr/lib. – Arnout Feb 19 '19 at 08:37
  • Hi) Thanks for the reply!) I've build everything with buildroot using buildroot toolchain option. I didn't do 'make clean' when i rebuilt my rootfs though, I'll try this just now... Should my rootfs contains /etc/ld.so.cache file after rebuild? – Andy Feb 19 '19 at 09:26
  • I've rebuild zImage after 'make clean' and now libraries seem to be loaded (sshd seems to be able to start during boot). But now login prompt dissapeared, but I think it is a different problem connected with something else in the configuration – Andy Feb 19 '19 at 09:43
  • It just was ssh-keygen which was generating new host keys too long (I'm using initramfs)... – Andy Feb 19 '19 at 09:58
