Hello,
in the project I'm working, I have todo Perl-Programming.
But in a free minute I compiled OCaml on the workstation.
The compilation was without problems, it seems.
But the ocaml-distri (3.09.2) compiled as 32-Bit.
I asked the admin, and he said, it's a 64-Bit workstation.
The first lines that I got from "prtdiag" are:
===================================================================
System Configuration: Sun Microsystems sun4u Sun Fire E4900
System clock frequency: 150 MHz
Memory size: 32768 Megabytes
===================================================================
Should I write a Bugmessage to the OCaml-Bugtracker?
Ciao,
Oliver

This doesn't mean the compiler is set to generate 64bit objects
by default, iirc the solaris 8 boxes I worked on ran 64 bit on
64 bit and nevertheless compiled stuff as 32bit. (yay).
See if you can pass a CPPFLAGS=-m64 to your compiler (gcc option,
if you're using sunpro pass the appropriate flag to the compiler
to enable/force 64bit compiling)...
I.e. no ocaml bug.
Maybe have a look at (gcc: gcc -dumpspecs which should among many
other things also tell you the default build/compile options...
E.g. on my sparc64, gcc tells me ...
*cpp_arch:
%{m32:%(cpp_arch32)} %{m64:%(cpp_arch64)} %{!m32:%{!m64:%(cpp_arch_default)}}
(read as: passed m32? select cpp_arch32. passed m64? select cpp_arch64.
passed neither m32 nor m64 ? select cpp_arch_default.)
..and..
*cpp_arch32:
*cpp_arch64:
-D__arch64__
*cpp_arch_default:
-D__arch64__
)
Regards,

I doubt setting gcc-Flags make sense, if this is not a flag,
that the ./configure-script inthe sources-directory accepts.
I hope there is such an 64-Bit-option in the configure-script,
if not, I think such flags could yield problems.

At least theconfigure-script did not find out that the machine
is a 64-Bit's machine. So at least the config-script could be
changed. (Or there is an 64-Bit-option, which I didn't checked,
because I thought, it will find it out by itself.

Hoi & ugh.

My fault. I'm used to autoconf scripts, and setting the environment
variable 'CPPFLAGS' (C pre processor flags) will pass additional
flags to the C compiler. This doesn't seem to be an autoconf build
though, sorry.
What I said about code generation and the default setting of your
machine's host compiler remains true :)

It did not find an 64bit env because your compiler by default
doesn't offer a 64bit env :)
Good luck ...

INRIA does not support 64 bit native code on SPARC
because they do not have any such systems. I have
a patch for version 3.09.1:
http://www.mit.edu/~jfc/ocaml-3.09.1-sparc64.tar.gz
Tk will not compile with this patch (this is a longstanding
problem that I intend to fix, but I want to fix it right
rather than accomodating the awful code generated for large
inner module initializers).
You may find 32 bit code to be adequate for your needs.
My program that uses Int32 and Int64 runs significantly
faster in 64 bit mode. You can also expect floating point
to be faster. Ordinary integer code is likely to be slower
because all the objects are bigger.

I picked up an old Ultra 5 the other day. Ocaml seems to work on it out
of the box in the limited amount of use I've put it to so far, except
for ocamlopt, which didn't build, dying trying to compile sparc.S with
register-related errors. I'll try that patch tomorrow when I have time,
see how it works outside of Solaris - I'm running NetBSD/sparc64 3.0.1.
