Thanks for pointing this out.

This indicates that the ldm-mcidas decoders have been linked against the
shared LDM library, not the static one.  Setting of the LD_LIBRARY_PATH
environment variable to include the directory in which the LDM shared
library is installed is one way to take care of the load problem.  The
other approach that I favor is to link the decoders against the static
LDM library.  This way one does not have to muck with LD_LIBRARY_PATH.

re:

I will need to update the ldm-mcidas build procedure to "burn" the
location of the LDM shared library into the ldm-mcidas executables.

I will take a closer look at the ldm-mcidas build examples/instructions
and get back to with the settings for linking statically and for
"burning" the location of the LDM shared library into the executables.

Cheers,

Tom
