在Suse Enterprise Linux Server上为Itanium64构建openjdk7

Question

我在运行Suse Linux Enterprise Server 11 SP2的Itanium服务器上构建openjdk7时遇到了一个棘手的问题。

我已经成功安装了Sun JDK 1.6更新33来作为安装的引导程序。 而且，我已经下载了源代码，并将openJDK7安装源解压缩到一个目录中。 我的构建通过了所有make sanity检查，看起来可以使用了。

我未设置JAVA_HOME，声明为LANG = C，并将构建指向引导JDK。

然后我调用make ALLOW_DOWNLOADS=false ALT_BOOTDIR=/usr/java/jdk1.6.0_33 ALT_DROPS_DIR=~/openjdk_src/sourcedrop

构建可以正常运行约5-10分钟，然后出现一连串关于找不到SSL库的错误。

这发生在jaxws源代码树的构建的以下部分中，并且似乎与SSL有关：

要解决此问题，我将jsse.pack解压缩到jdk/jre/bin中的jsse.jar中。

然后，如果我记得使用make ALLOW_DOWNLOADS=false ALT_BOOTDIR=/usr/java/jdk1.6.0_33 ALT_DROPS_DIR=~/openjdk_src/sourcedrop DISABLE_HOTSPOT_OS_VERSION_CHECK=ok可以make ALLOW_DOWNLOADS=false ALT_BOOTDIR=/usr/java/jdk1.6.0_33 ALT_DROPS_DIR=~/openjdk_src/sourcedrop DISABLE_HOTSPOT_OS_VERSION_CHECK=ok地忽略体系结构。

当在VM中建立adlc时，构建便会失败：

Making adlc

怎么办？ 什么是adlc，为什么不建立？

Answer 1

我最近才偶然发现这个问题（仍然悬而未决），最近几个月我曾尝试过类似的尝试。 并且也遇到（并解决了）相同的问题。

ADLC. “ adlc”是HotSpot的体系结构描述语言编译器， ADLC。 它用于生成HotSpot构建的Java执行引擎（解释器和JIT编译器）的源代码。 基于处理“ .ad ”文件。 如果并且当您构建ADLC工具时，其“用法”如下所示：

$> ./adlc
Architecture Description Language Compiler

Usage: adlc [-doqwTs] [-#]* [-D<FLAG>[=<DEF>]] [-U<FLAG>] [-c<CPP_FILE_NAME>] [-h<HPP_FILE_NAME>] [-a<DFA_FILE_NAME>] [-v<GLOBALS_FILE_NAME>] <ADL_FILE_NAME>
 d  produce DFA debugging info
 o  no output produced, syntax and semantic checking only
 q  quiet mode, supresses all non-essential messages
 w  suppress warning messages
 T  make DFA as many subroutine calls
 s  output which instructions are cisc-spillable
 D  define preprocessor symbol
 U  undefine preprocessor symbol
 c  specify CPP file name (default: (null))
 h  specify HPP file name (default: (null))
 a  specify DFA output file name
 v  specify adGlobals output file name
 #  increment ADL debug level

您的构建问题是您无法避免“架构”检测！ （实际上，甚至可能怀疑您使用“ DISABLE_HOTSPOT_OS_VERSION_CHECK = ok”。）但是，它比（仅仅是）更糟糕：IA64（与Windows分开，直到Windows Server 2008 R2结束（扩展）支持）...直到2020年？）已从Java 7 OpenJDK源树中删除，并且位已删除/正在主动删除（和/或未维护？）。 具体地说，这就是Makefile支持系统的某些HotSpot / OpenJDK构建配置组件所要解决的问题，该组件必须指定所有体系结构资格来定位/处理Linux Itanium / IA64体系结构上所需的“ .ad ”文件。 具体来说，您缺少正确的文件名扩展所需的某些关键定义： [...]/cpu/ia64/vm/.ad和../generated/adfiles/linux_.ad是不正确的，在结构上完全符合标准文件/目标（因此未找到）。

上面涉及的文件/目标的实际名称实际上是../generated/adfiles/linux_ia64.ad ，它是通过目标名称中的环境变量替换来实现的，但是缺少${arch_model}定义（类似的情况）呈现另一个envvar， ${os_arch_model} ）。 [JDK_distribution]/hotspot/make的“ linux ”目录下的“ platform_ia64 ”中没有这些（是（忽略）？）。 ia64 , and similarly, ' os_arch_model ' takes the same value as ' os_arch ', linux_ia64 . 其他平台的文件在linux下的简要回顾，你应该看到，“ arch_model ”应采取“价值arch ”， ia64 ，同样，“ os_arch_model ”采用相同的值是“ os_arch ”， linux_ia64 。

[Java7 JDK distribution]/hotspot/make $ cat platform_ia64
os_family = linux
arch = ia64
arch_model = ia64                      # Added
os_arch = linux_ia64
os_arch_model = linux_ia64             # Added
lib_arch = ia64
compiler = gcc
gnu_dis_arch = ia64
sysdefs = -DLINUX -D_GNU_SOURCE -DIA64 -DCC_INTERP
mark_style = alignment

仅通过该修改/修正，您就可以成功完成OpenJDK构建的这些初始步骤。 （我可以通过ADLC构建，但是稍后在另一个源区域中从后来的IA64源中删除的构建过程失败了。）祝您好运！
