OpenJDKをビルドしてみた
環境はMac。
基本ソースをMercurialでクローンしてREADME読めばできる。
READMEにもあるけど、詳しいビルド方法はここを参照すればいい。
http://hg.openjdk.java.net/jdk8/jdk8/raw-file/tip/README-builds.html
以下、作業手順。
デバッグ版が欲しい場合は Configure時に--enable-debug するとよい。
% hg clone http://hg.openjdk.java.net/jdk8/jdk8 jdk8_src
requesting all changes
adding changesets
adding manifests
adding file changes
added 942 changesets with 1309 changes to 136 files
updating to branch default
82 files updated, 0 files merged, 0 files removed, 0 files unresolved
% cd jdk8_src
% ./get_source.sh

====================================================
A new configuration has been successfully created in
/Users/plugram/Desktop/jvm/jdk8_src/build/macosx-x86_64-normal-server-fastdebug
using configure arguments '--enable-debug --with-target-bits=64'.
Configuration summary:
* Debug level: fastdebug
* JDK variant: normal
* JVM variants: server
* OpenJDK target: OS: macosx, CPU architecture: x86, address length: 64
Tools summary:
* Boot JDK: java version "1.8.0_20" Java(TM) SE Runtime Environment (build 1.8.0_20-b26) Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode) (at /Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/Contents/Home)
* C Compiler: i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build) version 2335.15.00) (at /usr/llvm-gcc-4.2/bin/llvm-gcc-4.2)
* C++ Compiler: i686-apple-darwin11-llvm-g++-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build) version 2335.15.00) (at /usr/llvm-gcc-4.2/bin/llvm-g++-4.2)
Build performance summary:
* Cores to use: 2
* Memory limit: 4096 MB
* ccache status: not installed (consider installing)
Build performance tip: ccache gives a tremendous speedup for C++ recompilations.
You do not have ccache installed. Try installing it.

インストールしたら /usr/local/bin に入った。
さっそく実験。
以下のようなソースを書いて実行。
