Linux 下編譯openjdk

操做系統ubuntu14.04

openjdk版本 7u4

openjdk7u4能夠在https://jdk7.java.net/source.html下載

 

一.構建編譯環境

sudo apt-get install build-essential gawk m4 openjdk-6-jdk
libasound2-dev libcups2-dev libxrender-dev xorg-dev xutils-dev
x11proto-print-dev binutils libmotif3 libmotif-dev ant

 

二.設置環境變量

export LANG=C

#編譯openjdk7所須要的jdk目錄,注意jdk的版本
#試過jdk1.8和1.7的其餘版本,在運行時就出現bug
export ALT_BOOTDIR=/home/foreverenjoy/Program/jdk1.7.0_04

export ALLOW_DOWNLOADS=true
export USE_PRECOMPILED_HEADER=true
export SKIP_DEBUG_BUILD=false
export SKIP_FASTDEBUG_BUILD=true
export DEBUG_NAME=debug

unset CLASSPATH
unset JAVA_HOME

 

三.檢查設置是否正確

在終端輸入make sanity

  1 ( cd  ./jdk/make && \
  2       make sanity HOTSPOT_IMPORT_CHECK=false JDK_TOPDIR=/home/foreverenjoy/Program/openjdk/jdk JDK_MAKE_SHARED_DIR=/home/foreverenjoy/Program/openjdk/jdk/make/common/shared EXTERNALSANITYCONTROL=true SOURCE_LANGUAGE_VERSION=7 TARGET_CLASS_VERSION=7 MILESTONE=internal BUILD_NUMBER=b00 JDK_BUILD_NUMBER=b00 FULL_VERSION=1.7.0-internal-debug-foreverenjoy_2016_07_03_19_04-b00 PREVIOUS_JDK_VERSION=1.6.0 JDK_VERSION=1.7.0 JDK_MKTG_VERSION=7 JDK_MAJOR_VERSION=1 JDK_MINOR_VERSION=7 JDK_MICRO_VERSION=0 PREVIOUS_MAJOR_VERSION=1 PREVIOUS_MINOR_VERSION=6 PREVIOUS_MICRO_VERSION=0 ARCH_DATA_MODEL=64 VARIANT=DBG DEBUG_CLASSFILES=true COOKED_BUILD_NUMBER=0 ALT_OUTPUTDIR=/home/foreverenjoy/Program/openjdk/build/linux-amd64 ALT_LANGTOOLS_DIST=/home/foreverenjoy/Program/openjdk/build/linux-amd64/langtools/dist ALT_CORBA_DIST=/home/foreverenjoy/Program/openjdk/build/linux-amd64/corba/dist ALT_JAXP_DIST=/home/foreverenjoy/Program/openjdk/build/linux-amd64/jaxp/dist ALT_JAXWS_DIST=/home/foreverenjoy/Program/openjdk/build/linux-amd64/jaxws/dist ALT_HOTSPOT_IMPORT_PATH=/home/foreverenjoy/Program/openjdk/build/linux-amd64/hotspot/import BUILD_HOTSPOT=true ; )

四.開始編譯

在終端輸入make

等一段時間

#-- Build times ----------
Target debug_build
Start 2016-07-03 19:25:12
End   2016-07-03 19:41:06

編譯完成

 

在OpenJDK目錄下有個build文件夾是編譯的output文件夾 

foreverenjoy@foreverenjoy:~/Program/openjdk$ cd build/
foreverenjoy@foreverenjoy:~/Program/openjdk/build$ ls -l
total 8
drwxrwxr-x 29 foreverenjoy foreverenjoy 4096  7月  3 19:41 linux-amd64

編譯結果

 

五.遇到的問題

1.

symbol JVM_FindClassFromCaller, version SUNWprivate_1.1 not defined in file libjvm.so with link time reference

刪除hotspot/make/linux/Makefile中全部的test_gamma ( 即刪掉全部的&& ./test_gamma)

將CurrencyData.properties內的時間改成10年內

 

六.在NetBeans編譯運行HotSpot

NetBeans下載地址：http://netbeans.org/   下載時選擇支持C/C++開發的版本。

 

首先新建項目，選擇 基於現有源代碼的C/C++選項

 

在 源碼文件夾中填入OpenJDK目錄下hotspot目錄的路徑,在下面的單選按鈕中選擇「定製」，點擊下一步

 

 

預構建模塊中的設置以下：

 

進入下一步，在Build Comman中輸入

#當前目錄爲hotspot，make後加參數-C make/ -f Makefile,make會在讀取Makefile以前改變到目錄hotspot/make/
${MAKE} -C make/ -f Makefile clean jvmg  ALT_BOOTDIR=/home/foreverenjoy/Program/jdk1.7.0_04 ARCH_DATA_MODEL=64 LANG=C

而後一直點擊下一步，結束後右擊項目，點擊Build。

 

Build成功以後，右擊項目，選擇項目屬性。

修改Run Cammand，Run Directory和添加Environment(環境變量)

 

Run Cammand:
#運行ClaA類
/home/foreverenjoy/Program/openjdk/hotspot/build/linux/linux_amd64_compiler2/jvmg/gamma ClaA

Run Directory:
/home/foreverenjoy/Program/openjdk/hotspot/build/linux/linux_amd64_compiler2/jvmg

ClASSPATH:
#/home/foreverenjoy/Program/javaProject是ClaA的目錄
.:${JAVA_HOME}/jre/lib/rt.jar:${JAVA_HOME}/jre/lib/i18n.jar:/home/foreverenjoy/Program/javaProject

JAVA_HOME:
/home/foreverenjoy/Program/jdk1.7.0_04

LD_LIBRARY_PATH:
.:${JAVA_HOME}/jre/lib/amd64/native_threads:${JAVA_HOME}/jre/lib/amd64:

最後點擊Run就能夠了
