NAME¶

jbuilder-external-lib-deps - Print out external libraries needed to build the given targets.

SYNOPSIS¶

jbuilder external-lib-deps [OPTION]... TARGET...

DESCRIPTION¶

Print out the external libraries needed to build the given targets.

The output of jbuild external-lib-deps @install should be included in what is written in your <package>.opam file.

OPTIONS¶

--help[=FMT] (default=auto)

Show this help in format FMT. The value FMT must be one of `auto', `pager', `groff' or `plain'. With `auto', the format is `pager` or `plain' whenever the TERM env var is `dumb' or undefined.

--missing

Only print out missing dependencies

--version

Show version information.

COMMON OPTIONS¶

These options are common to all commands.

--debug-backtraces

Always print exception backtraces.

--debug-dependency-path

In case of error, print the dependency path from the targets on the command line to the rule that failed.

--debug-findlib

Debug the findlib sub-system.

--dev

Use stricter compilation flags by default.

-j JOBS (absent=4)

Run no more than JOBS commands simultaneously.

--no-buffer

Do not buffer the output of commands executed by jbuilder. By default jbuilder buffers the output of subcommands, in order to prevent interleaving when multiple commands are executed in parallel. However, this can be an issue when debugging long running tests. With --no-buffer, commands have direct access to the terminal. Note that as a result their output won't be captured in the log file. You should use this option in conjunction with -j 1, to avoid interleaving. Additionally you should use --verbose as well, to make sure that commands are printed before they are being executed.

--only-packages=PACKAGES

Ignore stanzas referring to a package that is not in PACKAGES. PACKAGES is a comma-separated list of package names. Note that this has the same effect as deleting the relevant stanzas from jbuild files. It is mostly meant for releases. During development, it is likely that what you want instead is to build a particular <package>.install target.

-p PACKAGES, --for-release-of-packages=PACKAGES

Shorthand for --root . --only-packages PACKAGE. You must use this option in your <package>.opam files, in order to build only what's necessary when your project contains multiple packages as well as getting reproducible builds.

--root=DIR

Use this directory as workspace root instead of guessing it. Note that this option doesn't change the interpretation of targets given on the command line. It is only intended for scripts.

--verbose

Print detailed information about commands being run

--workspace=FILE

Use this specific workspace file instead of looking it up.

MORE HELP¶

Use `jbuilder COMMAND --help' for help on a single command.
