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.

(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, -Martin ^ permalink raw reply [flat|nested] 6+ messages in thread

[...] 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. > > I.e. no ocaml bug. > 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.

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 :) > (...) > At least theconfigure-script did not find out that the machine > is a 64-Bit's machine.

It did not find an 64bit env because your compiler by default doesn't offer a 64bit env :) Good luck ... -Martin ^ permalink raw reply [flat|nested] 6+ messages in thread

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. ^ permalink raw reply [flat|nested] 6+ messages in thread

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. ^ permalink raw reply [flat|nested] 6+ messages in thread
