If Z3 was installed into the ocamlfind package repository (see src/api/ml/README),
|
|
||||||
then we can compile this example as follows:
|
|
||||||
|
|
||||||
ocamlfind ocamlc -o ml_example.byte -package Z3 -linkpkg ml_example.ml
|
|
||||||
ocamlfind ocamlopt -o ml_example -package Z3 -linkpkg ml_example.ml
|
|
||||||
|
|
||||||
Note that the resulting binaries depend on the shared z3 library, which needs to be
|
|
||||||
in the PATH (Windows), LD_LIBRARY_PATH (Linux) or DYLD_LIBRARY_PATH (OSX). If Z3 was
|
|
||||||
installed into ocamlfind, the path that should be added is
|
|
||||||
`ocamlfind printconf destdir`/Z3
