问题描述

在哪里可以找到一组简单的说明来编译Ubuntu 11.10上的 OpenJDK 7调试版本（Oneiric ）？调试版本将使更多JVM选项可用于故障排除;例如， WizardMode 。 开发人员指南和构建README 有很多噪音，很难遵循。

Where can I find a simple set of instructions to compile an OpenJDK 7 debug build on Ubuntu 11.10 (Oneiric)? A debug build would make more JVM options available for troubleshooting purposes; for example, WizardMode. The developers' guide and build README have a lot of noise and are hard to follow.

推荐答案

• 安装相关软件包：



sudo apt-get install ant build-essential openjdk-6-jdk
sudo apt-get build-dep openjdk-6-jdk







• 找到您要开始的主人 OpenJDK Mercurial资源库。这些说明将使用 jdk7u2 。


• 命令示例包含允许通过代理服务器进行Internet访问的设置;


• 克隆Mercurial顶级林存储库：


• Find the master OpenJDK Mercurial repository you want to start from. These instructions will use jdk7u2.
• Command examples contain settings to allow Internet access through a proxy server; remove them if they are unnecessary for you.
• Clone the Mercurial top-level forest repository:

$ 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。根据建议此处，使用以下方法修补相应的 Makefile ：


• The build will fail while compiling the sound libraries. As suggested here, use the following to patch the appropriate 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/ li>
  
• 验证构建：



$ build/linux-amd64-fastdebug/j2sdk-image/bin/java -version
openjdk version "1.7.0-internal-fastdebug"
OpenJDK Runtime Environment (build 1.7.0-internal-fastdebug-user_2012_01_28_13_25-b00)
OpenJDK 64-Bit Server VM (build 22.0-b10-fastdebug, mixed mode)
$ build/linux-amd64-fastdebug/j2sdk-image/bin/java -XX:+AggressiveOpts -XX:+UnlockDiagnosticVMOptions -XX:+PrintFlagsFinal -XX:+PrintFlagsWithComments -version







• 如果您有问题，请先阅读 OpenJDK开发人员指南和 OpenJDK Build README 。


• If you have problems along the way, begin by reading The OpenJDK Developers' Guide and the OpenJDK Build README.
