[Caml-list] compilation problem

[Caml-list] compilation problem

Hello,

These times i'm trying (for school purposes) to write a compiler for a mini functional language based on Caml.
To do so, i've written several files (parser, lexer, errors, location, and a main one) that are interdependent....
I've recently added a semantic analyser only dealing with type check....
And when i use the command "make" :
this message is displayed on the screen :

No implementation provided for the following modules :

Errors referenced from main.cmx
Location referenced from main.cmx
Anasem referenced from main.cmx

I sadly can't understand the nature of the error I made.
Indeed i get all the files errors.ml, location.ml and anasem.ml " with all the needed interfaces .mli.....
If I'm missing something important please let me know...
Thanks.

Have you compiled them all and told the compiler to link main with them?
OCamlMakefile might be what you are looking for.

[Caml-list] compilation problem

[altavillasalvatore]

Hi,
I would want to compile the pascal.ml file:

****
pascal.ml
 open Unix
      let my_name =Unix.gethostname();;
******
I type

 ocamlc -custom unix.cma pascal.ml -cclib -lunix  

and then

 ocamlc pascal.ml -o pascal

obtaining the following message:

 Reference to undefined global `Unix'  

I would want the exec -file.

Regards.

The first command you typed is also used to create an executable (by default
a.out), since you did not provide the -c (compile only) or -a (create a library)
flags.

Change the first command to :
ocamlc -o pascal -custom unix.cma pascal.ml -cclib -lunix 

to create the executable with the name 'pascal'.

You could also have compiled pascal.ml :
ocamlc -c pascal.ml  (creates pascal.cmo and pascal.cmi)

then you could have created an executable with the compiled file :
ocamlc -o pascal -custom unix.cma -cclib -lunix pascal.cmo
