在哪里可以找到一组简单的指令来编译Ubuntu 11.10(Oneiric)上的
OpenJDK 7调试版本?调试版本将使更多JVM选项可用于故障排除;例如,WizardMode.
developers’ guide和
build README有很多噪音,很难遵循.
>安装相关包:
原文链接:https://www.f2er.com/ubuntu/349201.htmlsudo apt-get install ant build-essential openjdk-6-jdk sudo apt-get build-dep openjdk-6-jdk
>找到您想要开始的主OpenJDK Mercurial repository.这些说明将使用jdk7u2.
>命令示例包含允许通过代理服务器访问Internet的设置;如果它们对您不必要,请将它们删除.
>克隆Mercurial顶级林存储库:
$mkdir jdk7u2 $cd jdk7u2 $hg --config http_proxy.host=proxy:1234 clone http://hg.openjdk.java.net/jdk7u/jdk7u2 forest $cd forest $sh ./get_source.sh
>编译声音库时,构建将失败.根据建议here,使用以下内容修补相应的Makefile:
$echo -e "--- old/jdk/make/javax/sound/jsoundalsa/Makefile 2012-01-28 12:00:00.000000000 -0500\n+++ new/jdk/make/javax/sound/jsoundalsa/Makefile 2012-01-28 12:00:00.000000000 -0500\n@@ -65,7 +65,7 @@\n \t\$(MIDIFILES_export) \\\\\n \t\$(PORTFILES_export)\n\n-LDFLAGS += -lasound\n+EXTRA_LIBS += -lasound\n \n CPPFLAGS += \\\\\n \t-DUSE_DAUdio=TRUE \\\\" | patch -p1
>编译:
$export LANG=C ALT_BOOTDIR=/usr/lib/jvm/java-6-openjdk ANT_OPTS="-Dhttp.proxyHost=proxy -Dhttp.proxyPort=1234 -Dhttps.proxyHost=proxy -Dhttps.proxyPort=1234" $. jdk/make/jdk_generic_profile.sh $make ALLOW_DOWNLOADS=true fastdebug_build
>编译需要一段时间.
