which library must be linked to ?

Answer 1

I believe you need to compile it with the makefile. Type
make -f demo_makefile.mk cdemo81.cfrom the directory and it should work.
This worked for everyone else but in my computer I then get
libcltsh.so.8.0 not found (although the driver is there)
Anyone hope it works for you
