戯れにOCaml 3.12.0 beta1を入れてみた

はじめに

とりあえず出ているのでビルドしてみただけです。

configure

まずmakeの準備。一応ビルドしておく。GNU makeじゃないとだめ。

$ sudo port install gmake
$ make -v

つぎにconfigureする。

$ mkdir /opt/ocaml/ocaml3.12.0b1
$ curl http://caml.inria.fr/pub/distrib/ocaml-3.12/ocaml-3.12.0+beta1.tar.bz2 > ocaml-3.12.0+beta1.tbz
$ tar xjf ocaml-3.12.0+beta1.tbz
$ cd ocaml-3.12.0+beta1
$ ./configure -prefix /opt/ocaml/3.12.0b1 -cc "gcc -m64"
...

** Objective Caml configuration completed successfully **

make

これもINSTALLに書いてある通りにビルドするだけ。

$ make world
$ make bootstrap
$ make opt
$ make opt.opt
$ sudo umask 022
$ sudo make install
$ make clean

あまりに順調に行ってしまって非常につまらない。

テストしてみる

$ rlwrap ocaml
        Objective Caml version 3.12.0+beta1
