Hi,
Thanks. One more naive difficulty :
I could do #use "topfind"
but #require "lacaml" wasnt successful. It says no such packgae found
though I have lacaml installed in the same /usr/lib64/ocaml directory.
I have also added required variables to PATH and LD_LIBRARY_PATH.
It does not show lacaml after "#list" too. I reinstalled lacaml but
same thing again. What can be the reason?
Regardsm
Onkar
