ocamlopt
OCaml native-code compiler
TLDR
Compile to native code
$ ocamlopt -o [program] [source.ml]
Compile multiple files$ ocamlopt -o [program] [file1.ml] [file2.ml]
Compile with optimization$ ocamlopt -O3 -o [program] [source.ml]
Compile to object file$ ocamlopt -c [source.ml]
Create native library$ ocamlopt -a -o [library.cmxa] [file1.ml] [file2.ml]
SYNOPSIS
ocamlopt [options] files...
DESCRIPTION
ocamlopt is the OCaml native-code compiler. It produces fast executables by compiling OCaml to native machine code instead of bytecode.
Native code runs significantly faster than bytecode but isn't portable across architectures.
PARAMETERS
-o file
Output filename.-c
Compile only.-O level
Optimization level (0-3).-I dir
Include directory.-g
Debug info.-a
Create library.-inline n
Inline threshold.

CAVEATS
Compilation slower than bytecode. Platform-specific output. Debugging harder than bytecode.
HISTORY
The OCaml native compiler was developed at INRIA to provide high-performance compilation while maintaining OCaml's type safety.
