去年就嘗試過自己編譯 JDK，但是失敗了，最近在分析 Java 虛擬機是如何處理 Linux 信號的時候，雖然大體流程清晰了，但是還是有很多方面無法理解，所以編譯調試 JDK 勢在必行。
我的操作系統版本：macOS Catalina 10.15.5。
安裝 XCode 和 Commnad Line Tools for XCode
這個應該是可以不安裝的，但是爲了避免出現依賴問題，我還是安裝了。
安裝版本：11.5 (11E608c)。
獲取 OpenJDK 源碼
OpenJDK 是使用 Mercurial 進行代碼管理的，Mercurial 很小衆，那還要再安裝 Mercurial，感覺沒必要，而且聽說拉源碼的時候網絡很容易斷。這裏直接下載下來：http://jdk.java.net/
我一開始選擇了 8，源碼下載下來後，查看一下說明：
坑爹的是看到了這個：
想想也是，8 其實已經算是一個老版本了，印象中編輯 JDK 之前需要準備一個 N-1 版本的可用的 Bootstrap JDK，我本機已經裝了 JDK 11:
➜ ~ java11
➜ ~ java -version
java version "11.0.2" 2019-01-15 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.2+9-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.2+9-LTS, mixed mode)
那我換一個下載 12:
macOS
Apple is using a quite aggressive scheme of pushing OS updates, and coupling these updates with required updates of Xcode. Unfortunately, this makes it difficult for a project such as the JDK to keep pace with a continuously updated machine running macOS. See the section on Apple Xcode on some strategies to deal with this.
It is recommended that you use at least Mac OS X 10.13 (High Sierra). At the time of writing, the JDK has been successfully compiled on macOS 10.12 (Sierra).
The standard macOS environment contains the basic tooling needed to build, but for external libraries a package manager is recommended. The JDK uses homebrew in the examples, but feel free to use whatever manager you want (or none).
Apple Xcode
The oldest supported version of Xcode is 8.
看着版本勉強應該可以契合，先試試。
準備環境
根據網上資料顯示，需要安裝這麼幾個：
brew install ccache //加速編譯
brew install freetype //字體引擎，編譯過程中會被依賴到
安裝過程中更新 Homebrew 花了很長時間。
Configure 檢查
首先需要配置編譯參數，building.html 也有參數說明：
Configure Arguments for Tailoring the Build
--enable-debug- Set the debug level tofastdebug(this is a shorthand for--with-debug-level=fastdebug)--with-debug-level=- Set the debug level, which can berelease,fastdebug,slowdebugoroptimized. Default isrelease.optimizedis variant ofreleasewith additional Hotspot debug code.--with-native-debug-symbols=- Specify if and how native debug symbols should be built. Available methods arenone,internal,external,zipped. Default behavior depends on platform. See Native Debug Symbols for more details.--with-version-string=- Specify the version string this build will be identified with.--with-version-=- A group of options, where `` can be any ofpre,opt,build,major,minor,securityorpatch. Use these options to modify just the corresponding part of the version string from the default, or the value provided by--with-version-string.--with-jvm-variants=[,...]- Build the specified variant (or variants) of Hotspot. Valid variants are:server,client,minimal,core,zero,custom. Note that not all variants are possible to combine in a single build.--with-jvm-features=[,...]- Use the specified JVM features when building Hotspot. The list of features will be enabled on top of the default list. For thecustomJVM variant, this default list is empty. A complete list of available JVM features can be found usingbash configure --help.--with-target-bits=- Create a target binary suitable for running on a `` platform. Use this to create 32-bit output on a 64-bit build platform, instead of doing a full cross-compile. (This is known as a reduced build.)On Linux, BSD and AIX, it is possible to override where Java by default searches for runtime/JNI libraries. This can be useful in situations where there is a special shared directory for system JNI libraries. This setting can in turn be overriden at runtime by setting the
java.library.pathproperty.
--with-jni-libpath=- Use the specified path as a default when searching for runtime libraries.
爲了便於以後再回過頭看，我這裏完成記錄命令執行過程：

Runnable configure script is not present
Generating runnable configure script at /Users/dongguabai/Desktop/temp/openjdk12/openjdk/build/.configure-support/generated-configure.sh
Autoconf is not found on the PATH, and AUTOCONF is not set.
You need autoconf to be able to generate a runnable configure script.
You might be able to fix this by running 'brew install autoconf'.
Error: Cannot find autoconf
發現報錯了，缺少 autoconf，還是那句話，要認真讀文檔啊：
Build Tools Requirements
Autoconf
The JDK requires Autoconf on all platforms. At least version 2.69 is required.
- To install on an apt-based Linux, try running
sudo apt-get install autoconf.- To install on an rpm-based Linux, try running
sudo yum install autoconf.- To install on macOS, try running
brew install autoconf.- To install on Windows, try running
/setup-x86_64 -q -P autoconf.If
configurehas problems locating your installation of autoconf, you can specify it using theAUTOCONFenvironment variable, like this:AUTOCONF=<path to autoconf> configure ...
安裝 autoconf 後再走一遍：
➜ openjdk brew install autoconf

顯示與 with-freetype 有關，根據 building.html 的說明：
FreeType
FreeType2 from The FreeType Project is not required on any platform. The exception is on Unix-based platforms when configuring such that the build artifacts will reference a system installed library, rather than bundling the JDK’s own copy.
- To install on an apt-based Linux, try running
sudo apt-get install libfreetype6-dev.- To install on an rpm-based Linux, try running
sudo yum install freetype-devel.- To install on Solaris, try running
pkg install system/library/freetype-2.Use
--with-freetype-include=and--with-freetype-lib=ifconfiguredoes not automatically locate the platform FreeType files.
既然是這樣的話，那我乾脆就不指定 freetype，如果找不到我再指定，修改參數後再操作一次：
