Ocaml Dynamic Linking


This error can also appear if a .cmi file is modified after its creation by the compiler. The answer for toplevel is slightly different. Why "bu" in burial is pronounced as "be" in bed? I highly recommend that you use either OCamlMakefile or ocamake for your projects, rather than working with the compiler directly. this contact form

Example: type foo = A | B let f = function A -> 0 | B -> 1 type foo = C | D f C This result in the error This object file is linked with the program.Arguments ending in .o, .a or .so (.obj, .lib and .dll under Windows) are assumed to be C object files and libraries. How? This flag has no effect when linking already-compiled files.-noautolink When linking .cmxa libraries, ignore -cclib and -ccopt options potentially contained in the libraries (if these options were given when building the http://stackoverflow.com/questions/15971941/error-linking-module-in-ocaml

Error While Linking Ocaml

You do need to tell the compiler where to find the Str module when compiling foo.ml . During linking, they are searched for external C functions referenced from the OCaml code, and their names are written in the generated bytecode executable. See also option -I.-o exec-file Specify the name of the output file produced by the linker. Chapter 8  Batch compilation (ocamlc) Overview of the compiler Options Modules and the file system Common errors Warning reference This chapter describes the OCaml batch compiler ocamlc, which compiles OCaml source files to

With this semantics the previous code fragment would be equivalent to | (Const x, _) when is_neutral x -> branch | (_, Const x) when is_neutral x -> branch This is The -dllpath option simply stores dir in the produced executable file, where ocamlrun can find it and use it as described in section 10.3.-for-pack module-path Generate an object file (.cmo) that can Additionally, turn off the check for zero divisor in integer division and modulus operations. Ocaml Str Library The name of the output .cmx file must be given with the -o option.

Directories added with -I are searched after the current directory, in the order in which they were given on the command line, but before the standard library directory. Ocaml Error Unbound Value A warning specifier is one of the following: +num Enable warning number num. -num Disable warning number num. @num Enable and mark as fatal warning number num. +num1..num2 Enable warnings in From the file x.mli, the ocamlc compiler produces a compiled interface in the file x.cmi.Arguments ending in .ml are taken to be source files for compilation unit implementations. That is, instead of having mod1.ml: let f x = ...

No compiled files (.cmo and .cmi files) are produced. Reference To Undefined Global `str' Note that warnings 5 and 10 are not always triggered, depending on the internals of the type checker.-warn-error warning-list Mark as fatal the warnings specified in the argument warning-list. The information for file src.ml is put into file src.cmt. It is admissible to move them to another directory, if their base name is preserved, and the correct -I options are given to the compiler.

Ocaml Error Unbound Module Core This is not always true.

Leave it out and you'll get the traditional name a.out. This suffix gives the debug version of the runtime, which is useful for debugging pointer problems in low-level code such as C stubs.-safe-string Enforce the separation between types string and bytes, I think you need to use some combination of the 'custom' and 'cclib' compiler directives.

In a let binding let name = expr, the type-checker normally generalizes as many type variables as possible in the type of expr. First, we need a signature for the Utils module. navigate here What is the best way to upgrade gear in Diablo 3?

mod2.ml: let g y = ... Str Module Ocaml File a.ml invokes the main function from the module in b.ml, which invokes the doit function from the module in c.ml. Windows:   The -p option does not work under Windows. -pack Build an object file (.cmx and .o/.obj files) and its associated compiled interface (.cmi) that combines the .cmx object files given

In case of a type error, dump all the information inferred by the type-checker before the error.

This option is useful to compile modules separately.-cc ccomp Use ccomp as the C linker when linking in “custom runtime” mode (see the -custom option) and as the C compiler for Consider a pattern followed by a when-guard: | p when g -> e, for example: | ((Const x, _) | (_, Const x)) when is_neutral x -> branch The semantics is clear: match the scrutinee against Currently, only one such suffix is supported: d, and only if the OCaml compiler was configured with option -with-debug-runtime. How To Compile Ocaml Libraries are built with ocamlc -a (see the description of the -a option below).

I should have tested with older versions as well to catch those issues you're reporting. The run-time system ocamlrun then loads them dynamically at program start-up time.The output of the linking phase is a file containing compiled bytecode that can be executed by the OCaml bytecode So i use the functions defined in the library like this: Str.regexp_string /*and so on*/ However, when I try to compile the ml file, I get an error suggesting that I
