compilation - 在 Suse Enterprise Linux Server 上构建适用于 Itanium64 的 openjdk7

Question

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

我已成功安装 Sun JDK 1.6 update 33 作为安装的 Bootstrap 。而且，我已经下载了源代码并将 openJDK7 安装源解压到一个目录中。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 源代码树中构建的以下部分中，并且似乎与 SSL 有关:

为了解决这个问题，我将 jsse.pack 解压到 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 来忽略架构。

当在虚拟机中生成 adlc 时，构建会失败:

现在怎么办？什么是 adlc？为什么它不能构建？

Answer 1

我最近才偶然发现这个(仍然悬而未决)的问题，近几个月来尝试过类似的事情；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。如果您获得要构建的 ADLC 工具，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! (事实上​​，您对“DISABLE_HOTSPOT_OS_VERSION_CHECK=ok”的使用甚至可能值得怀疑。)但是，它比(仅)更糟糕: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/正在被主动删除(和/或没有得到维护？)。具体来说，这就是 Makefile 支持系统的某些 HotSpot/OpenJDK 构建配置组件的问题，该系统是指定所有架构资格来定位/处理 Linux Itanium/IA64 架构上所需的“.ad”文件所必需的。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 显然不是正确的、完全架构限定的文件/目标名称(因此未找到)。

上面涉及的文件/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而产生的，但缺少 ${arch_model} 的定义(另一个环境变量 ${os_arch_model} 也存在类似的情况)。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'应该采用'arch'的值，即ia64，同样，'os_arch_model'采用与'os_arch'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

仅通过该修改/更正，您就应该能够成功完成 OpenJDK 构建的这些初始步骤。(我可以通过 ADLC 构建，但后来在构建过程中失败，因为另一个源代码区域已从后来的 IA64 源代码中删除......)祝您好运!
