OCaml on Windows help

[Raj Bandyopadhyay]

Hi

I installed OCaml on Windows XP (the MSVC version, since I assume  
that's faster than
the Cygwin version?). I'm having trouble compiling OCaml programs  
from the command line and I wonder if it's a bug or just my lack of  
Windows knowledge.

I created a sample program test.ml and here's what happens

 > ocamlopt -o test.exe test.ml
-----------
'ml' is not recognized as an internal or external command,
operable program or batch file

Assembler error, input left in file....
-------------

Using ocamlc instead of ocamlopt seems to work fine, at least there are
no compilation errors.

Any suggestions on what I should do?

Thanks
Raj

The "'ml' is not recognized..." message is a windows message telling
that it is trying to run the test.ml file.
You could try again after renaming ocamlopt into ocamlopt.exe (if it's
not already), windows has _some_ problems with file extensions (and I
recall seeing a few ocaml executable without .exe extension).
You can also try with quotes around "test.ml".

Good luck

MinGW/Cygwin is faster than MSVC port for bytecode. README.win32 contains a
full comparison of the three Windows ports. I don't know whether anyone's
benchmarked MASM vs Gas for performance of programs compiled with ocamlopt,
however...

I ran into the same problem this week.

ml.exe is the executable name of the Microsoft assembler.  The error is 
confusing due to the coincidence that the assember's name is the same as 
the OCaml file extension.    It has nothing to do with trying to execute 
the test.ml file.

ocamlc was working because it doesn't need any of the Microsoft tools to 
build executable programs.

The INSTALL.win32 file is  a big help.   Once I installed the components 
it indicated, I'm able to use ocamlopt.   It was challenging though to 
get the windows executable and lib paths set correctly so that ocamlopt 
would use the tools it was designed for.  (I had several versions of 
many programs that were for other unrelated purposes.)  As best as I can 
tell, I also had to rebuild OCaml because I was using MSVC 6 and getting 
link errors.   I think this was due to ocamlopt trying to combine the 
released version of 3.10.0 with the run time libraries that I have which 
mixed versions of the MSVC libraries.
