在 Suse Enterprise Linux 服务器上为 Itanium64 构建 openjdk7答案

【问题标题】：Building openjdk7 for Itanium64 on Suse Enterprise Linux Server在 Suse Enterprise Linux 服务器上为 Itanium64 构建 openjdk7
【发布时间】：2012-06-27 16:15:00
【问题描述】：

我在运行 Suse Linux Enterprise Server 11 SP2 的安腾服务器上构建 openjdk7 时遇到了一些棘手的问题。

我已经成功安装了 Sun JDK 1.6 update 33 作为安装的引导程序。而且，我已经下载了源文件并将 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，看起来已经准备就绪。

我已取消设置 JAVA_HOME，声明 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

构建运行正常大约 5-10 分钟，然后我收到一串关于未找到 SSL 库的错误。

这发生在 jaxws 源代码树的以下构建段中，并且似乎与 SSL 有关：

为了解决这个问题，我将jsse.pack 解压缩到jdk/jre/bin 中的jsse.jar。

那如果我记得用make ALLOW_DOWNLOADS=false ALT_BOOTDIR=/usr/java/jdk1.6.0_33 ALT_DROPS_DIR=~/openjdk_src/sourcedrop DISABLE_HOTSPOT_OS_VERSION_CHECK=ok 忽略架构就好了。

当它在 VM 中生成 adlc 时，构建会失败：

Making adlc

现在呢？什么是 adlc，为什么不能构建？

【解决方案1】：

我最近才偶然发现这个（仍然悬而未决的）问题，最近几个月尝试过类似的事情；并且也遇到（并解决了）同样的问题。

'adlc' 是 HotSpot 的架构描述语言编译器，即 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，它的“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，您使用“DISABLE_HOTSPOT_OS_VERSION_CHECK=ok”，甚至可能是可疑的。）但是，它比（只是）更糟糕的是：IA64（除了 Windows，直到 Windows Server 2008 R2（扩展）支持结束...到 2020 年？）正在从 Java 7 OpenJDK 源代码树中删除，并且位已被删除/正在被积极删除（和/或没有被维护？）。具体来说，这就是Makefile-support 系统的一些 HotSpot/OpenJDK 构建配置组件的问题，这些组件是指定所有架构资格以在 Linux Itanium/ 上定位/处理所需的“.ad”文件所必需的。 IA64 架构。具体来说，您缺少正确文件名扩展所需的某些关键定义：[...]/cpu/ia64/vm/.ad 和 ../generated/adfiles/linux_.ad 显然不正确，文件/目标的完全架构限定名称（因此未找到）。

上述文件/目标的正确名称实际上是../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，但是对于${arch_model}的缺失定义（类似的情况出现在另一个envvar， ${os_arch_model})。这些在[JDK_distribution]/hotspot/make 的'linux' 目录下的'platform_ia64' 中不存在（疏忽？）。简单回顾一下 linux 下的其他平台文件，你应该看到'arch_model'应该取'arch'的值，即ia64，类似地，'@987654336 @' 与 'os_arch' 具有相同的值，即 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

仅通过修改/更正，您应该能够成功完成 OpenJDK 构建的这些初始步骤。（我可以通过 ADLC 构建，但后来由于从后来的 IA64 源中删除的另一个源区域的构建过程失败了......）祝你好运！
