编译 OpenJDK 源码

05 August 2019

1. 配置
2. 编译
3. 验证
4. 问题
- 1. unzip
- 2. zip
- 3. boot jdk
- 4. systemtap-sdt
- 5. X11
- 6. cups
- 7. font
- 8. alsa

测试环境:

Ubuntu 16.04
gcc 5.4.0
jdk11-1ddf9a99e4ad

下载 jdk11 的源代码:

mkdir jdk11 && cd jdk11
# http://hg.openjdk.java.net/jdk/jdk11/
wget http://hg.openjdk.java.net/jdk/jdk11/archive/tip.tar.gz
tar -xzf tip.tar.gz
cd jdk11-1ddf9a99e4ad/

通过 README 文档可得构建文档为:

doc/building.html (html version)

doc/building.md (markdown version)

阅读 doc/building.md, 可总结为一下四步:

Run configure: bash configure
Run make: make images
Verify your newly built JDK: ./build/*/images/jdk/bin/java -version
Run basic tests: make run-test-tier1(需要 JTReg)

安装编译基础工具:

sudo apt-get install build-essential

参考文档, 配置运行模式为server模式, 启用debug和dtrace:

bash configure --enable-debug --with-jvm-variants=server --enable-dtrace

1. 配置

运行命令:

bash configure --enable-debug --with-jvm-variants=server --enable-dtrace --with-boot-jdk=$HOME/jdk11/jdk-11.0.2

结果:

====================================================
A new configuration has been successfully created in
/home/cofcool/jdk11/jdk11-1ddf9a99e4ad/build/linux-x86_64-normal-server-fastdebug
using configure arguments '--enable-debug --with-jvm-variants=server --enable-dtrace --with-boot-jdk=/home/cofcool/jdk11/jdk-11.0.2'.

Configuration summary:
* Debug level:    fastdebug
* HS debug level: fastdebug
* JVM variants:   server
* JVM features:   server: 'aot cds cmsgc compiler1 compiler2 dtrace epsilongc g1gc graal jfr jni-check jvmci jvmti management nmt parallelgc serialgc services vm-structs'
* OpenJDK target: OS: linux, CPU architecture: x86, address length: 64
* Version string: 11-internal+0-adhoc.cofcool.jdk11-1ddf9a99e4ad (11-internal)

Tools summary:
* Boot JDK:       openjdk version "11.0.2" 2019-01-15 OpenJDK Runtime Environment 18.9 (build 11.0.2+9) OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)  (at /home/cofcool/jdk11/jdk-11.0.2)
* Toolchain:      gcc (GNU Compiler Collection)
* C Compiler:     Version 5.4.0 (at /usr/bin/gcc)
* C++ Compiler:   Version 5.4.0 (at /usr/bin/g++)

Build performance summary:
* Cores to use:   2
* Memory limit:   7965 MB

2. 编译

运行命令:

make images

结果:

Building target 'images' in configuration 'linux-x86_64-normal-server-fastdebug'
Compiling 8 files for BUILD_TOOLS_LANGTOOLS
Creating hotspot/variant-server/tools/adlc/adlc from 13 file(s)

...

Creating support/demos/image/jfc/SampleTree/SampleTree.jar
Creating support/demos/image/jfc/TableExample/TableExample.jar
Creating support/demos/image/jfc/TransparentRuler/TransparentRuler.jar
Creating jdk image
Stopping sjavac server
Finished building target 'images' in configuration 'linux-x86_64-normal-server-fastdebug'

3. 验证

运行命令:

build/linux-x86_64-normal-server-fastdebug/images/jdk/bin/java -version

结果:

openjdk version "11-internal" 2018-09-25
OpenJDK Runtime Environment (fastdebug build 11-internal+0-adhoc.cofcool.jdk11-1ddf9a99e4ad)
OpenJDK 64-Bit Server VM (fastdebug build 11-internal+0-adhoc.cofcool.jdk11-1ddf9a99e4ad, mixed mode)

如需测试，需在编译配置期间配置JTReg，添加 --with-jtreg=<path>, 运行 make run-test-tier1 进行测试。

4. 问题

1. unzip

错误:

configure: error: Could not find required tool for UNZIP

解决:

sudo apt install unzip

2. zip

错误:

checking for zip… no

解决:

sudo apt install zip

3. boot jdk

错误:

configure: Could not find a valid Boot JDK. You might be able to fix this by running ‘sudo apt-get install openjdk-8-jdk’.

根据提示安装”jdk 8”

sudo apt-get install openjdk-8-jdk

但是仍旧报错，提示”Boot JDK”版本需为 10 或 11

configure: Potential Boot JDK found at /usr/lib/jvm/java-1.8.0-openjdk-amd64 is incorrect JDK version (openjdk version “1.8.0_222”); ignoring configure: (Your Boot JDK version must be one of: 10 11) configure: Could not find a valid Boot JDK. You might be able to fix this by running ‘sudo apt-get install openjdk-8-jdk’. configure: This might be fixed by explicitly setting –with-boot-jdk

下载配置”openjdk-11.0.2”即可

wget https://download.java.net/java/GA/jdk11/9/GPL/openjdk-11.0.2_linux-x64_bin.tar.gz
tar -xzf openjdk-11.0.2_linux-x64_bin.tar.gz

配置添加--with-boot-jdk即可

bash configure --enable-debug --with-jvm-variants=server --enable-dtrace --with-boot-jdk=$HOME/jdk11/jdk-11.0.2

4. systemtap-sdt

错误:

configure: error: Cannot enable dtrace with missing dependencies. See above. You might be able to fix this by running ‘sudo apt-get install systemtap-sdt-dev’.

解决:

sudo apt-get install systemtap-sdt-dev

5. X11

错误:

configure: error: Could not find all X11 headers (shape.h Xrender.h XTest.h Intrinsic.h). You might be able to fix this by running ‘sudo apt-get install libx11-dev libxext-dev libxrender-dev libxtst-dev libxt-dev’.

解决:

sudo apt-get install libx11-dev libxext-dev libxrender-dev libxtst-dev libxt-dev

6. cups

错误:

checking cups/ppd.h presence… configure: error: Could not find cups! You might be able to fix this by running ‘sudo apt-get install libcups2-dev’.

解决:

sudo apt-get install libcups2-dev

7. font

错误:

configure: error: Could not find fontconfig! You might be able to fix this by running ‘sudo apt-get install libfontconfig1-dev’

解决:

sudo apt-get install libfontconfig1-dev

8. alsa

错误:

configure: error: Could not find alsa! You might be able to fix this by running ‘sudo apt-get install libasound2-dev’.

解决:

sudo apt-get install libasound2-dev
