[Caml-list] ocamlopt under win32
Philip A. Viton
Can anyone tell me what's going wrong here?
Computer: running win xp/sp2 on amd 64
ocamlopt: 3.09.0
ms files: from visual studio 6
I try the following (the smallest independent part of the Hevea distribution):
==== non verbose =====
C:\ProgramFiles\OCaml\hevea\hevea-1.09\native>
c:\ProgramFiles\ocaml\bin\ocamlopt -c bibhva.ml

Error during linking
This link failure (with the same unresolved externals message)
appears for all other parts of the hevea distribution too, so it
seems that something is going wrong with any attempt to link.
There's an earlier message on the list to the effect that VC6 isn't
usable with the most recent ocaml distribution: is this really true?
There's also a remark in the most recent ocaml bugfix release to the
effect that something is being fixed specifically for the AMD chip :
could that be the problem?
Any help very gratefully received!

The MSVC binary distribution for OCaml 3.09 was built with Visual C++ 2003,
which is binary-incompatible with Visual Studio 6. There is also
Visual C++ 2005 and the Platform SDK compilers, all from Microsoft,
all subtly incompatible with each other. Complain with Microsoft if
you feel like it.
If you just want to generate .exe files for Windows, may I suggest you
use the MinGW version of OCaml and avoid the MSVC one? MinGW, besides
being free, is also more stable than Microsoft's dev. tools.
