That's it! Everything builds, links and runs fine! Thank you!

Three problems:
1) -c turns linking off, while you really want to do a
(partial) link here.
2) The compilation of lexer.ml already
produces lexer.obj, so you give lexer.obj both as input and as output
to the partial linker, which can break things.
3) With the MSVC port, the output of the partial linker is a .lib file,
not a .obj file, so it would be prudent to name the output
appropriately.
Try this instead:
ocamlopt -output-obj -o lexer.lib lexer.ml
Hope this helps,

I've added stdlib.lib and I'm compiling the C file with ocamlopt now, but
things still aren't working. The link errors for the Lexing module are
gone, but they were replaced by many more from stdlib.lib.
Where are the functions _caml_curry2/3 or _caml_apply2/3/4 defined? They
aren't in libasmrun.lib, I verified that with dumpbin. I'm using Ocaml
3.06.

Hello everyone!
I'm trying to add some ocaml code (a simple lexer/parser) to an existing C
application and I'm having problems linking the whole thing on Windows.
Needless to say, everything works fine under Unix (Mac OS X). I'm using
the MSVC version of ocaml.
Here's are the commands that I use to build the whole thing:
cl /c /nologo /MT /I "C:\Program Files\Objective Caml\lib" main.c
ocamllex lexer.mll
ocamlopt -c -output-obj lexer.ml -o lexer.obj
cl -o test main.obj lexer.obj /link /nologo
/libpath:"c:\progra~1\object~1\lib" libasmrun.lib
And here are the link errors that result from the last command:
lexer.obj : error LNK2001: unresolved external symbol _Lexing__engine_117
lexer.obj : error LNK2001: unresolved external symbol
_Lexing__from_function_140
lexer.obj : error LNK2001: unresolved external symbol _Lexing__lexeme_155
lexer.obj : error LNK2001: unresolved external symbol
_Pervasives__close_out_232
lexer.obj : error LNK2001: unresolved external symbol
_Pervasives__open_out_202
lexer.obj : error LNK2001: unresolved external symbol
_Pervasives__output_string_214
lexer.obj : error LNK2001: unresolved external symbol _caml_curry2
libasmrun.lib(startup.obj) : error LNK2001: unresolved external symbol
_caml_code_segments

I'm sure I'm missing something obvious, but I can't figure it out. Thanks
in advance,
Peter
