Module Unix.LargeFile

Instructions: Use this module in your project

In the IDE (CLion, Visual Studio Code, Xcode, etc.) you use for your DkSDK project:

Add the following to your project's dependencies/CMakeLists.txt:

Copy

DkSDKProject_DeclareAvailable(ocaml
    CONSTRAINT "= 4.14.0"
    FINDLIBS str unix runtime_events threads dynlink)
DkSDKProject_MakeAvailable(ocaml)

Add the Findlib::ocaml library to any desired targets in src/*/CMakeLists.txt:

Copy

target_link_libraries(YourPackage_YourLibraryName
     # ... existing libraries, if any ...
     Findlib::ocaml)

Click your IDE's Build button

Not using DkSDK?

FIRST, do one or all of the following:

Run:
Copy
```
opam install ocaml.4.14.0
```

Edit your dune-project and add:

Copy

(package
  (name YourExistingPackage)
  (depends
  ; ... existing dependenices ...
  (ocaml (>= 4.14.0))))

Then run:

Copy

dune build *.opam # if this fails, run: dune build

Edit your <package>.opam file and add:

Copy

depends: [
  # ... existing dependencies ...
  "ocaml" {>= "4.14.0"}
]

Then run:

Copy

opam install . --deps-only

FINALLY, add the unix library to any desired (library)and/or (executable) targets in your **/dune files:

Copy

(library
  (name YourLibrary)
  ; ... existing library options ...
  (libraries
    ; ... existing libraries ...
    unix))

(executable
  (name YourExecutable)
  ; ... existing executable options ...
  (libraries
    ; ... existing libraries ...
    unix))
