前回 (GraalVMを試してみた) の続きです。
結論として、Rails5.2は動きませんでした。面倒くさいので途中でやめました。
Railsを試してみる
rubyは同梱されていないが、1コマンドでtrufflerubyがインストールできる。
[root@centos-local ~]# gu -c install org.graalvm.ruby
Downloading: Component catalog

Downloading: Component org.graalvm.ruby
Installing new component: Truffle.Ruby (org.graalvm.ruby, version 1.0.0-rc1)
[root@centos-local ~]# ruby -v
truffleruby 1.0.0-rc1, like ruby 2.3.7 <native build with Graal> [x86_64-linux]
bundlerインストール。
[root@centos-local ~]# gem install bundler
ERROR: Loading command: install (RuntimeError)
you may need to install the system OpenSSL library libssl - see doc/user/installing-libssl.md (libssl.so: 共有オブジェクトファイルを開けません: そのようなファイルやディレクトリはありません)
ERROR: While executing gem ... (NoMethodError)
undefined method `invoke_with_build_args' for nil:NilClass
opensslがないと怒られたので入れる。
yum install -y openssl-devel
再チャレンジしたら成功した。1gemインストールするだけなのに10分くらい時間がかかった。

unsupported clang version: 3.4.2とある。しまった、バージョン確認し忘れた。
GithubのIssueによるとCurrently, the script accepts LLVM 3.8, 3.9, 4.0 and 5.0.とある。
StackOverFlowの投稿を参考にclang3.9をインストールする。
