ocamldebug — the OCaml source-level replay debugger.
ocamldebug [ options ] program [ arguments ]
ocamldebug is the OCaml source-level replay debugger.
Before the debugger can be used, the program must be compiled and linked with the -g option: all .cmo and .cma files that are part of the program should have been created with ocamlc -g, and they must be linked together with ocamlc -g.
Compiling with -g entails no penalty on the running time of programs: object files and bytecode executable files are bigger and take longer to produce, but the executable files run at exactly the same speed as if they had been compiled without -g.
A summary of options are included below. For a complete description, see the html documentation in the ocaml-doc package.
- -c count
Set the maximum number of simultaneously live checkpoints to count.
- -cd dir
Run the debugger program from the working directory dir, instead of the current working directory. (See also the cd command.)
Tell the debugger it is executed under Emacs. (See The OCaml user's manual for information on how to run the debugger under Emacs.) Implies -machine-readable.
- -I directory
Add directory to the list of directories searched for source files and compiled files. (See also the directory command.)
Print information in a format more suitable for machines instead of human operators where applicable. For example, when describing a location in a program, such as when printing a backtrace, print the program counter and character offset in a file instead of the filename, line number, and character offset in that line.
- -s socket
Use socket for communicating with the debugged program. See the description of the command set socket in The OCaml user's manual for the format of socket.
Print version string and exit.
Print short version number and exit.
- -help or --help
Display a short usage summary and exit.
When ocamldebug(1) is invoked, it will read commands from an initialization file before giving control to the user. The default file is .ocamldebug in the current directory if it exists, otherwise .ocamldebug in the user's home directory.
Note that you can also use the source file command to read commands from a file.
