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...
