Hi Beata,
Before linking your application, you need to tell your dynamic linker, ld.so,
where to look for the shared libraries to use. One way to do this is by
setting the LD_LIBRARY_PATH environment variable, as in:
$ export LD_LIBRARY_PATH=${NCPATH}/lib:${LD_LIBRARY_PATH}
See the man page for ld.so for other ways to do the same thing, including
use of LD_RUN_PATH during linking, or use of the `-Wl,-rpath -Wl,LIBDIR'
linker flags.
