You will need a working objective caml installation and the FaCiLe library properly configured and installed to compile eqchem. In practice, one would only run make in this directory (src/solver) "make" "make clean", etc To assemble with a c++ or a kde program, the object files solver.o and modwrap.o must be added and linked with : -L/usr/lib/ocaml -L/usr/lib/ocaml/facile -lasmrun -lstr -lnums -lm -ldl solver.o modwrap.o The program built can then be run without the objective caml tools. Console examples can also be generated (try "make test") Thomas Nagy
