[Caml-list] OCamlMake and cmo files

[Caml-list] OCamlMake and cmo files

[Flavio]

Hello all,
Sorry if this is obvious, but I tried on the beginners list with no 
luck, so...

I'm trying to use OCamlMake from Markus Mottl but don't know what to do 
with .cmo files.
My Makefile is: (file editor2.ml is the example from lablgtk2 package)

OCAMLMAKEFILE = /usr/share/ocaml-tools/OCamlMakefile

SOURCES = editor2.ml
RESULT  = editor2
INCDIRS = +lablgtk2
LIBS = lablgtk gtkInit

include $(OCAMLMAKEFILE)

and the error is 
ocamlc  -I +lablgtk2 lablgtk.cma gtkInit.cma -o editor editor.cmo
Cannot find file gtkInit.cma

Right, the file is gtkInit.cmo but if i add the extension to the 
filename it tells: Cannot find file gtkInit.cmo.cma

Am I missing something obvious?

There is a good reason why this is handled this way: the extension
differs for byte- and native code libraries.

If you want to link anything that is only available in byte code (or
pass special flags to the byte code linker), just use the variable
OCAMLBLDFLAGS (see README in the distribution for details). Everything
you put in there will be passed verbatim in the linking stage.

Now my Makefile is:

OCAMLMAKEFILE = /usr/share/ocaml-tools/OCamlMakefile

SOURCES = editor2.ml
RESULT  = editor2
INCDIRS = +lablgtk2
LIBS = lablgtk

OCAMLBLDFLAGS = gtkInit.cmo

but this executes
ocamlc -I +lablgtk2 gtkInit.cmo lablgtk.cma -o editor2 editor2.cmo

that gives an error because the right order is (lablgtk.cma first):
ocamlc -I +lablgtk2 lablgtk.cma gtkInit.cmo -o editor2 editor2.cmo

And now?

Many thanks for your help (and patience)

Well, that's easy ;-)

How about

  OCAMLBLDFLAGS = lablgtk.cma gktInit.cmo

and dropping "LIBS = lablgtk"?
