MLPOST(1) General Commands Manual MLPOST(1)NAME
mlpost - wrapper around OCaml and Metapost for the Mlpost library
SYNOPSIS
mlpost [options] files...
DESCRIPTION
mlpost is a program that compiles OCaml files to PostScript or PDF files using the Mlpost library.
OPTIONS -pdf Generate .mps files (default)
-mp Generate .mp files
-png Generate .png files
-ps Generate .1 files
-latex <main.tex>
Scan the LaTeX prelude
-eps Generate encapsulated postscript files
-xpdf WYSIWYG mode using xpdf remote server (the name of the remote server is "mlpost")
-v Be a bit more verbose. Otherwise nothing is printed except in case of error.
-ocamlbuild
Use ocamlbuild to compile
-native
Compile to native code
-ccopt <options>
Pass <options> to the Ocaml compiler
-execopt <options>
Pass <options> to the compiled program
-version
Print Mlpost version and exit
-no-magic
Do not parse mlpost options, do not call Metapost.dump
-depend
output dependency lines in a format suitable for the make(1) utility
-contrib <contrib-name>
compile with the specified contrib
-dumpable
output one name of dumpable file by line. So it print all the figures which will be created by the .ml file.
-get-include-compile {cmxa|cma|dir|file}
output the libraries which are needed by the library Mlpost if you want not to use the mlpost tool :
- cmxa print the needed cmxa file (opt version)
- cma print the needed cma file (byte version)
- dir print the directories needed to be include
- file print the file name inside this directory without extension
-compile-name <compile-name>
Keep the compiled version of the .ml file and name it <compile-name>.
-dont-execute
Don't execute the mlfile. So mlpost generates no figures. With this option you can check that a file compile without wasting time to
generate the figures. The options -dont-execute and -compile-name can be used in conjunction to create a program which generates
some figures according to some command line options.
-dont-clean
Don't remove intermediates files. The metapost backend use some intermediates files which are removed without this option.
-cairo Use the cairo backend instead of metapost
-t1disasm
Set the program used to decrypt PostScript Type 1 font, only with cairo (default built-in one). This option will disappear soon.
-help, --help
Display the list of options

jocamlc - The JoCaml bytecode compiler
SYNOPSIS
jocamlc [ -aciv ] [ -cclib libname ] [ -ccopt option ] [ -custom ] [ -unsafe ] [ -o exec-file ] [ -I lib-dir ] filename ...
jocamlc.opt (same options)
DESCRIPTION
The JoCaml bytecode compiler jocamlc(1) compiles Caml source files to bytecode object files and link these object files to produce stand-
alone bytecode executable files. These executable files are then run by the bytecode interpreter jocamlrun(1).
The jocamlc(1) command has a command-line interface similar to the one of most C compilers. It accepts several types of arguments and pro-
cesses them sequentially:
Arguments ending in .mli are taken to be source files for compilation unit interfaces. Interfaces specify the names exported by compilation
units: they declare value names with their types, define public data types, declare abstract data types, and so on. From the file x.mli,
the jocamlc(1) compiler produces a compiled interface in the file x.cmi.
Arguments ending in .ml are taken to be source files for compilation unit implementations. Implementations provide definitions for the
names exported by the unit, and also contain expressions to be evaluated for their side-effects. From the file x.ml, the jocamlc(1) com-
piler produces compiled object bytecode in the file x.cmo.
If the interface file x.mli exists, the implementation x.ml is checked against the corresponding compiled interface x.cmi, which is assumed
to exist. If no interface x.mli is provided, the compilation of x.ml produces a compiled interface file x.cmi in addition to the compiled
object code file x.cmo. The file x.cmi produced corresponds to an interface that exports everything that is defined in the implementation
x.ml.
Arguments ending in .cmo are taken to be compiled object bytecode. These files are linked together, along with the object files obtained
by compiling .ml arguments (if any), and the Caml Light standard library, to produce a standalone executable program. The order in which
.cmo and.ml arguments are presented on the command line is relevant: compilation units are initialized in that order at run-time, and it is
a link-time error to use a component of a unit before having initialized it. Hence, a given x.cmo file must come before all .cmo files that
refer to the unit x.
Arguments ending in .cma are taken to be libraries of object bytecode. A library of object bytecode packs in a single file a set of object
bytecode files (.cmo files). Libraries are built with ocamlc -a (see the description of the -a option below). The object files contained in
the library are linked as regular .cmo files (see above), in the order specified when the .cma file was built. The only difference is that
if an object file contained in a library is not referenced anywhere in the program, then it is not linked in.
Arguments ending in .c are passed to the C compiler, which generates a .o object file. This object file is linked with the program if the
-custom flag is set (see the description of -custom below).
Arguments ending in .o or .a are assumed to be C object files and libraries. They are passed to the C linker when linking in -custom mode
(see the description of -custom below).
jocamlc.opt is the same compiler as jocamlc, but compiled with the native-code compiler jocamlopt(1). Thus, it behaves exactly like
jocamlc, but compiles faster. jocamlc.opt is not available in all installations of JoCaml.
OPTIONS
The following command-line options are recognized by jocamlc(1).
-a Build a library (.cma file) with the object files (.cmo files) given on the command line, instead of linking them into an executable
file. The name of the library can be set with the -o option. The default name is library.cma.
-c Compile only. Suppress the linking phase of the compilation. Source code files are turned into compiled files, but no executable
file is produced. This option is useful to compile modules separately.
-cclib -llibname
Pass the -llibname option to the C linker when linking in ``custom runtime'' mode (see the -custom option). This causes the given C
library to be linked with the program.
-ccopt Pass the given option to the C compiler and linker, when linking in ``custom runtime'' mode (see the -custom option). For instance,
-ccopt -L dir causes the C linker to search for C libraries in directory dir.
-custom
Link in ``custom runtime'' mode. In the default linking mode, the linker produces bytecode that is intended to be executed with the
shared runtime system, jocamlrun(1). In the custom runtime mode, the linker produces an output file that contains both the runtime
system and the bytecode for the program. The resulting file is larger, but it can be executed directly, even if the jocamlrun(1)
command is not installed. Moreover, the ``custom runtime'' mode enables linking Caml code with user-defined C functions.
-i Cause the compiler to print all defined names (with their inferred types or their definitions) when compiling an implementation (.ml
file). This can be useful to check the types inferred by the compiler. Also, since the output follows the syntax of interfaces, it
can help in writing an explicit interface (.mli file) for a file: just redirect the standard output of the compiler to a .mli file,
and edit that file to remove all declarations of unexported names.
-I directory
Add the given directory to the list of directories searched for compiled interface files (.cmi) and compiled object code files
(.cmo). By default, the current directory is searched first, then the standard library directory. 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.
-o exec-file
Specify the name of the output file produced by the linker. The default output name is a.out, in keeping with the Unix tradition. If
the -a option is given, specify the name of the library produced.
-v Print the version number of the compiler.
-unsafe
Turn bound checking off on array and string accesses (the v.(i) and s.[i] constructs). Programs compiled with -unsafe are therefore
slightly faster, but unsafe: anything can happen if the program accesses an array or string outside of its bounds.
