It's not just the file name - for reliable operation you want the same
minor version, since the header files you compiled against may define
things differently from what is appropriate for the libs on the board.
Indeed, there may be subtly different things in the library itself
from version to version, so I suggest you use the exact version of the
shared library on your target board.
  I dunno how you would find out the exact minor version from the
lib*.so.X file, but that path is fraught with woe - there are other
issues to do with the ABI: which floating point method is used, which
CPU model it is compiled for, whether functions have thumb
interworking enabled and so on.
  The *.so.5 - *.so.6 filename changes happen at majorly incompatible
system-wide ABI changes, such as happened between gcc-3.3 and gcc-3.4

It's trying to load kernel modules, probably to drive some device.
There needs to be /lib/modules/2.4.26-vrs1-cirrus-1-2-1-ts8 directory
into the same place on your target board - you should be able to find
this on whatever system your kernel came from.

Looks like some terminal driver. An alternative is to comment out the
"1:" line in /etc/inittab and "kill -1 1"

It needs to match the version of the kernel that is running,
obtainable from "uname -r"

You're welcome. Good luck!
