Can you show exactly how this error appears? If it appears when you try
to run the application, then it usually means that the kernel can't
find your dynamic library loader.

I never use Buildroot to generate a filesystem in which I'm chroot-ing.
If the target architecture is the same as the host, it should work, but
there might be issues, it's not the common use case for Buildroot
(usually, you take the generated root filesystem image and put it on a
target device).

The shared versions of the C library and related libraries (libm, etc.)
are in /lib, not in /usr/lib.
