Thank you; it seems to compile now, but it's crashing (runtime);
there's a library installed on my system that it's not picking up.
The error message is:
jonathan@inner-sanctum:~/csi/ml$ ocamlrun ocaml ./demo.ml
Cannot load required shared library dllpcre_stubs.
Reason: dllpcre_stubs.so: cannot open shared object file: No such file or directory.
Reference to undefined global `Pcre'
jonathan@inner-sanctum:~/csi/ml$
Slocate finds the library in /usr/lib/ocaml/3.08.3/stublibs/dllpcre_stubs.so ; do I need to tell the script to search there?
The script (missing " in" appended to the appropriate line) is:
#!/usr/bin/ocamlrun ocaml
