Erlangのインストール
まずはインストールできるversionを確認する
$ kerl list releases vagrant@vagrant
R10B-0 R10B-10 R10B-1a R10B-2 R10B-3 R10B-4 R10B-5 R10B-6 R10B-7 R10B-8 R10B-9 R11B-0 R11B-1 R11B-2 R11B-3 R11B-4 R11B-5 R12B-0 R12B-1 R12B-2 R12B-3 R12B-4 R12B-5 R13A R13B01 R13B02-1 R13B02 R13B03 R13B04 R13B R14A R14B01 R14B02 R14B03 R14B04 R14B_erts-5.8.1.1 R14B R15B01 R15B02 R15B02_with_MSVCR100_installer_fix R15B03-1 R15B03 R15B R16A_RELEASE_CANDIDATE R16B01 R16B02 R16B03-1 R16B03 R16B 17.0-rc1 17.0-rc2 17.0 17.1 17.3 17.4 17.5 18.0 18.1 18.2.1 18.2 18.3 19.0 19.1 19.2 19.3
Run '/usr/local/bin/kerl update releases' to update this list from erlang.org
今回は最新版の19.3をビルドする
$ kerl build 19.3 19.3 vagrant@vagrant
Verifying archive checksum...

* The documentation can not be built.
Erlang/OTP 19.3 (19.3) has been successfully built
なんか怪しげなログが流れているが、buildはできてるっぽい。
次はビルドされた言語本体をインストールする
$ kerl install 19.3 ~/kerl/19.3 vagrant@vagran
Installing Erlang/OTP 19.3 (19.3) in /home/vagrant/kerl/19.3...
You can activate this installation running the following command:
. /home/vagrant/kerl/19.3/activate
Later on, you can leave the installation typing:
kerl_deactivate
インストールされたものをディレクトリの中のみ有効にする。
例えば~/project/erlang内のみ有効にするには。
$ cd ~/project/erlang
$ . ~/kerl/19.3/activate
確認する
$ erl vagrant@vagrant
