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库的错误消息。
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拆包到jsse.jar中的jdk/jre/bin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进行制作，则会很好地忽略该体系结构。当在VM中建立adlc时，构建便会失败：

怎么办？什么是adlc，为什么不建立？
最佳答案
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”是HotSpot的体系结构描述语言编译器，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，其“用法”如下所示：
$> ./adlc
Architecture Description Language Compiler
Usage: adlc [-doqwTs] [-#]* [-D<FLAG>[=<DEF>]] [-U<FLAG>] [-c<CPP_FILE_NAME>] [-h<HPP_FILE_NAME>] [-a<DFA_FILE_NAME>] [-v<GLOBALS_FILE_NAME>] <ADL_FILE_NAME>
d produce DFA debugging info
o no output produced, syntax and semantic checking only
q quiet mode, supresses all non-essential messages
w suppress warning messages
T make DFA as many subroutine calls
s output which instructions are cisc-spillable
D define preprocessor symbol
U undefine preprocessor symbol
c specify CPP file name (default: (null))
h specify HPP file name (default: (null))
a specify DFA output file name
v specify adGlobals output file name
# increment ADL debug level
您的构建问题是您无法避免“架构”检测！ （实际上，甚至可能怀疑您使用“ DISABLE_HOTSPOT_OS_VERSION_CHECK = ok”。）但是，它比（仅仅是）更糟糕：IA64（与Windows分开，直到Windows Server 2008 R2结束（扩展）支持）...直到2020年？）已从Java 7 OpenJDK源代码树中删除，并且位已删除/正在主动删除（和/或未维护？）。具体地说，这就是
Makefile-支持系统的某些HotSpot / OpenJDK构建配置组件的问题，这些组件必须指定所有体系结构资格以定位/处理Linux Itanium /上必需的“ .ad”文件IA64体系结构。具体来说，您缺少正确的文件名扩展所需的某些关键定义：[...]/cpu/ia64/vm/.ad和../generated/adfiles/linux_.ad显然是不正确的，在结构上完全合格的文件/目标名称（因此未找到）。上面涉及的文件/目标的实际名称实际上是
../generated/adfiles/linux_ia64.ad，它是通过目标名称中的环境变量替换来实现的，但是缺少${arch_model}的定义（类似的情况是另一个环境变量${os_arch_model} ）。 platform_ia64的'linux'目录下的'[JDK_distribution]/hotspot/make'中没有这些（是疏忽大意吗？）。简要回顾一下Linux下的其他平台文件，您应该看到'arch_model'应该采用'arch'的值，即ia64，类似地，'os_arch_model'应该采用与'os_arch'，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/修正，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，但是稍后从另一个IA64源中删除了另一个源区域的构建过程失败了……）祝您好运！
