Dear all freinds,
When I compile a .ml file with ocamlopt compiler, an error message is shown
with this message:"Der Befehl "as" ist entweder falsch geschrieben oder
konnte nicht gefunden werden, Assembler error, input left in file
C:\DOKUME~1\karinu\LOKALE~1\Temp\camlasm9312 7a.s". Part of this message is
in german and translation of it in english is : "The instruction "as" is
either wrongly written or could not not be found". But when I compile a .mli
file, this message is not shown and file is compiled successfully. Also when
I compile a .ml file with ocamlc compiler, there is no error and compilation
is done successfully. So there is not error in my program and this error
maybe is related to ocamlopt compiler.
Is there any body who can help me? It is very emergent.
Thanks,
Karimi.

There is no reason that a particular error occurs with ocamlopt and
not ocamlc, especially as the syntax and typing phases are common to
both compilers (moreover, bugs in ocaml compilers are quite rare. Rule
of thumb: never suspect a bug in the compiler, always in your code).
So I would suspect an issue with your particular file or your
compiling environment. We cannot say much more without (1) having your
particular .ml and .mli file and (2) knowing in which environment your
are compiling.

Yours,
d.

Looks like as (the GNU portable assembler) is not installed, or at least not
in your $PATH...

The message is to be understood literally: in order to compile
assembly code to machine code, ocamlopt relies on an external
assembler. I suppose you use either the mingw or cygwin version, so
the name of the assembler is "as". You must make sure you installed it
with cygwin.
With a .mli, there is no object created, so no external command is
required. Similarly ocamlc generates bytecode all by itself, so there
is no such problem (as long as you don't use the -custom option.)

Hello Karimi,

I can see from the backslashes that Windows is
involved.

I have had some problems with Windows, but it works
now. I do not remember the error messages. Let me just
summarize all that you need:
- Install MS C++ and MS Assembler (free from the Web)
- make sure that all paths to bin directories are set
properly
- always work with the Console which is attached to
your C++ compiler (the icon is set up when you install
it), never the Windows Console

I use Windows 2000. I have never tried the other two
options for compiling under Windows (Cygwin etc.)

I also have Debian/Knoppix-Linux. There you install
everything easily as a Debian package with apt-get and
everything just works. OCaml is better supported under
Linux (debugger, more tools, GUIs etc.)

Regards,

Martin

ocamlopt problem

[David Allsopp]

I'm trying to build the ocamlodbc package under Windows using Cygwin/MinGW.
It's all built and working except that I'm having one problem with the
native library. My question, I think, relates to a misunderstanding with
ocamlopt so I'm hoping someone can point out my error! 

I've adapted the INSTALL_mingw.sh script to issue the following commands:

$ gcc -mno-cygwin -c -DODBC2 -DWIN32 -I $OCAMLLIB/caml -I
/usr/include/w32api ocaml_odbc_c.c
$ gcc -mno-cygwin -shared -L $OCAMLLIB -L $OCAMLLIB/../bin -o
dllocamlodbc.dll ocaml_odbc_c.o -lodbc32 -locamlrun 

$ ocamlopt -a -o ocamlodbc.cmxa ocaml_odbc_c.o ocaml_odbc.ml ocamlodbc.mli
ocamlodbc.ml -cclib -lodbc32
$ cp ocamlodbc.cmxa ocamlodbc.a ocamlodbc.cmi $OCAMLLIB

$ ocamlc -a -o ocamlodbc.cma ocaml_odbc.ml ocamlodbc.mli ocamlodbc.ml -dllib
-locamlodbc
$ cp ocamlodbc.cmi ocamlodbc.cma $OCAMLLIB
$ cp dllocamlodbc.dll $OCAMLLIB/stublibs

The top-level library ocamlodbc.cma is working exactly as I'd expect. I then
attempt to compile a program that uses the native library (in this case
Exemples/monitor.ml) with the command

ocamlopt -o monitor.exe ocamlodbc.cmxa monitor.ml

but get the response

gcc: ocaml_odbc_c.o: No such file or directory
Error during linking

Despite trying various -ccopt flags, the only way I can make it compile is
to copy ocaml_odbc_c.o to the current directory. My understanding is that
the ocamlopt statement that built ocamlodbc.cmxa should have included
ocaml_odbc_c.o so why is gcc getting a linker problem when referencing the
library?

Sorry if it's a blindingly obvious mistake...
