I'm trying to use cmake for a project using OCaml, so I'm trying to
add
support for a new language.
Among the many problems I encounter, the most pressing is the
following: the rule to build object files
(CMAKE_OCaml_COMPILE_OBJECT)
seems to want a command that takes <SOURCE> and generates <OBJECT>,
both
of which absolute file names.
Problems is, `ocamlc' seems to insist on sending the result to a file
name of its own choosing (basically <SOURCE> with the extension
modified). Worse yet: it generates 2 files (a .cmo object file and
a .cmi that is similar to a header file).
The rule below "works":
set (CMAKE_OCaml_COMPILE_OBJECT
"<CMAKE_OCaml_COMPILER> -c <SOURCE> \; mv \"$$(dirname
<SOURCE>)/$$(basename <OBJECT>)\" <OBJECT>")
but it's clearly not what we want.
- How do I tell Cmake that `ocamlc' generates 2 files?
- How do I tell Cmake that `ocamlc' does not let us choose where to
put
the result?
According to http://caml.inria.fr/pub/docs/manual-ocaml/manual022.html,
it does:
-o exec-file
Specify the name of the output file produced by the compiler. The
default output name is a.out under Unix and camlprog.exe under Windows.
If the -a option is given, specify the name of the library produced. If
the -pack option is given, specify the name of the packed object file
produced. If the -output-obj option is given, specify the name of the
output file produced. If the -c option is given, specify the name of the
object file produced for the next source file that appears on the
command line.
So using
set (CMAKE_OCaml_COMPILE_OBJECT "<CMAKE_OCaml_COMPILER> -c -o <OBJEJCT>
<SOURCE>")
does not work?
