ocaml_binary()
This is liable to change in the future.
A ocaml_binary() rule builds both native and bytecode executables from the supplied set of OCaml and C source files and dependencies.
Note: Buck is currently tested with 4.X OCaml series.
Arguments
name
(required) #The short name for this build target.
srcs
(required) #The set of source files to be compiled by this rule. It supports *.ml, *.mli, *.mly, *.mll, and *.c files. (see this test as C interop example and this test as parser and lexer example).
deps
(defaults to[]
) #The set of dependencies of this rule. It could include references to ocaml_library and cxx_library rules.
platform_deps
(defaults to[]
) #Platform specific dependencies. These should be specified as a list of pairs where the first element is an un-anchored regex (in java.util.regex.Pattern syntax) against which the platform name is matched, and the second element is a list of dependencies (same format as
deps
) that are exported if the platform matches the regex. Seedeps
for more information.compiler_flags
(defaults to[]
) #The set of additional compiler flags to pass to ocaml compiler. It supports specifying ppx (see for example).
visibility
(defaults to[]
) #List of build target patterns that identify the build rules that can include this rule as a dependency, for example, by listing it in their
deps
orexported_deps
attributes. For more information, see visibility.licenses
(defaults to[]
) #Set of license files for this library. To get the list of license files for a given build rule and all of its dependencies, you can use
buck query
.labels
(defaults to[]
) #Set of arbitrary strings which allow you to annotate a build rule with tags that can be searched for over an entire dependency tree using
buck query attrfilter()
.
