CentOS 6.9 Minimal 編譯OpenJDK 7
今天學習《深入理解Java虛擬機:JVM高級特性與最佳實踐》一書,並動手在Linux系統上編譯OpenJDK 7,初次搞不太順利,特記錄下編譯操作細節。
一、前期準備
約定:工具默認安裝目錄是/usr/local/,若有源碼,則源碼存放在/usr/local/src/目錄下。
1、OpenJDK
下載OpenJDK 7,地址:http://download.java.net/openjdk/jdk7/promoted/b147/openjdk-7-fcs-src-b147-27_jun_2011.zip,文件校驗碼:http://download.java.net/openjdk/jdk7/promoted/b147/openjdk-7-fcs-src-b147-27_jun_2011.md5
wget http://download.java.net/openjdk/jdk7/promoted/b147/openjdk-7-fcs-src-b147-27_jun_2011.zip # 下載
unzip openjdk-7-fcs-src-b147-27_jun_2011.zip # 解壓
mv openjdk openjdk7 # 更改目錄名
2、FreeType
筆者使用的是freetype-2.4.0.tar.gz,下載地址:https://sourceforge.net/projects/freetype/files/freetype2/2.4.0/
tar -zxvf freetype-2.4.0.tar.gz # 解壓
cd freetype-2.4.0
./configure && make && make install # 編譯安裝
3、Apache Ant
筆者使用的是apache-ant-1.9.7-bin.tar.gz,下載地址:https://archive.apache.org/dist/ant/binaries/
tar -zxvf apache-ant-1.9.7-bin.tar.gz # 解壓
mv apache-ant-1.9.7 /usr/local/
ln -s /usr/local/apache-ant-1.9.7/bin/ant /usr/bin/ant # 軟鏈接到bin
4、BootstrapJDK
筆者使用的是jdk-6u45-linux-x64,因為源碼更多是使用Java寫的,因此需要使用一個可用的JDK去編譯(詳見深入理解Java虛擬機第一章),OpenJDK解壓目錄下有個README-builds.html<OpenJDK Build README>,建議詳看一遍,文檔說使用JDK 6
下載jdk-6u45-linux-x64.bin,下載地址:http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase6-419409.html
./jdk-6u45-linux-x64.bin # 解壓
mv jdk1.6.0_45 /usr/local/ # 移動目錄
5、編譯需要的相關工具
yum -y install gcc gcc-c++ alsa-lib alsa-lib-devel libXrender libXrender-devel libXi-devel libXt-devel libXtst-devel cups cups-devel
二、配置環境變量
vim /etc/profile # 在末尾加入以下內容註意各個目錄Path
# openjdk 7 build
export ANT_HOME=/usr/local/apache-ant-1.9.7
export ALT_FREETYPE_HEADERS_PATH=/usr/local/include/freetype2
export ALT_FREETYPE_LIB_PATH=/usr/local/lib
export ALT_DROPS_DIR=/usr/local/src/openjdk7/drop
export ALT_BOOTDIR=/usr/local/jdk1.6.0_45
export ALT_JDK_IMPORT_PATH=/usr/local/jdk1.6.0_45
export ALT_OUTPUTDIR=/usr/local/openjdk7
export LANG=C
export HOTSPOT_BUILD_JOBS=8
export ALT_PARALLEL_COMPILE_JOBS=8
export SKIP_COMPARE_IMAGES=true
export USE_PRECOMPILED_HEADER=true
export ALLOW_DOWNLOADS=true
export SKIP_DEBUG_BUILD=false
export SKIP_FASTDEBUG_BUILD=true
export DEBUG_NAME=debug
unset JAVA_HOME
unset CLASSPATH
:wq # 寫入磁盤
source /etc/profile # 刷新環境變量配置使之生效,建議echo下幾個配置項確認生效,例:echo $LANG
cd openjdk7 # 進入OpenJDK解壓目錄
make sanity # 檢查之前的配置是否正確,若無錯誤(Sanity check passed.)則OK,下面是筆者的執行結果宮參考

三、編譯操作
make 2>&1 | tee $ALT_OUTPUTDIR/build.log # 編譯,標準錯誤輸出stderr重定向到標準輸出stdout,將編譯過程數據重定向到文件保存。
若編譯失敗,重新編譯前先執行:make clean
若編譯成功,提示信息如下:
-- Build times ----------
Target debug_build
Start 2018-04-30 23:30:30
End 2018-04-30 23:45:05
00:01:45 corba
00:03:32 hotspot
00:00:18 jaxp
00:00:24 jaxws
00:08:05 jdk
00:00:31 langtools
00:14:35 TOTAL
-------------------------
四、驗證
進入/usr/local/openjdk7/bin(即$ALT_OUTPUTDIR/bin)目錄,執行:./java -version
[root@dsp-centos-2-6_9 bin]# ./java -version
openjdk version "1.7.0-internal-debug"
OpenJDK Runtime Environment (build 1.7.0-internal-debug-root_2018_04_30_20_26-b00)
OpenJDK 64-Bit Server VM (build 21.0-b17-jvmg, mixed mode)
五、筆者碰到的問題
1、java.lang.RuntimeException: time is more than 10 years from present
修改jdk/src/share/classes/java/util/CurrencyData.properties,將日期改為十年以內,JDK的Bug。
108行改為: AZ=AZM;2009-12-31-20-00-00;AZN,接下來的377、439、529、555行類似修改保存,重新編譯。
2、/usr/local/openjdk7-debug/jaxws/build/xml_generated/build-drop-jaf_src.xml:96: Redirection detected from https to http. Protocol switch unsafe, not allowed.
原因是jdk7-jaf-2010_08_19.zip這個包下載不了導致的,解決方案:
將以下三個文件下載後置於OpenJDK解壓後根目錄下的drop目錄下,並在環境變量中加入配置:export ALT_DROPS_DIR=/usr/local/src/openjdk7/drop # 註意目錄Path
