MacOS 編譯OpenJDK13

官方說明 :

1. Get the complete source code:
   hg clone http://hg.openjdk.java.net/jdk/jdk

2. Run configure:
   bash configure

   If configure fails due to missing dependencies (to either the toolchain, build tools, external libraries or the boot JDK), most of the time it prints a suggestion on how to resolve the situation on your platform. Follow the instructions, and try running bash configure again.

3. Run make:
   make images

4. Verify your newly built JDK:
   ./build/*/images/jdk/bin/java -version

5. Run basic tests:
   make run-test-tier1

6.  

如何構建,可以查看裏面的文檔說明: doc/building.html

 

 

============  以下爲操作實例 ==============================================

 

1. 準備安裝環境:

 

1.首先需要準備一個Xcode

我用的是Xcode9.4.1 版本 .  [如果用其他高版本尚未測試.我編譯OpenJDK10的時候是報錯的.]

官方下載地址:   https://developer.apple.com/download/more/

網盤下載地址:    https://pan.baidu.com/s/1yp0eqLJtHV0X-ppcxeUewg  密碼:nnlt

 

2.JDK版本要求 12 或者13

 

3. brew 這個命令我就不說了, 去查一下,怎麼安裝.

brew install freetype ccache

brew install mercurial

 

在命令行輸入 hg 命令有如下輸出:

 

2.拉取源碼包:

 

git clone  [email protected]:openjdk/jdk13u.git

注: 這個超級難下載,易炸毛.   不過比 hg 下載容易多了...

下載完的目錄:

 

3.配置參數

 

接下來配置編譯參數，以下是相關選項說明

• --with-debug-level=slowdebug 啓用slowdebug級別調試
• --enable-dtrace 啓用dtrace
• --with-jvm-variants=server 編譯server類型JVM
• --with-target-bits=64 指定JVM爲64位
• --enable-ccache 啓用ccache，加快編譯
• --with-num-cores=8 編譯使用CPU核心數
• --with-memory-size=8000 編譯使用內存
• --disable-warnings-as-errors 忽略警告  , mac 使用 xcode 編譯, 官方要求加上這個參數.
• --with-freetype  設置freetype的路徑, 這個路徑必須爲你機器上的路徑,記得修改 !!!! 

 

$ bash configure --with-debug-level=slowdebug --enable-dtrace --with-jvm-variants=server --with-target-bits=64 --enable-ccache --with-num-cores=4 --with-memory-size=8000 --disable-warnings-as-errors

編譯完輸出:
