无法从源码，ubuntu 18.04、64位构建开放的jdk 8

Question

我试图通过此链接来构建自己的JDK：

http://hg.openjdk.java.net/jdk8/jdk8/raw-file/tip/README-builds.html#introduction

回顾一下步骤如下：

• hg克隆http://hg.openjdk.java.net/jdk8/jdk8 YourOpenJDK
• cd YourOpenJDK
• bash ./get_source.sh
• bash ./configure
• 全部制作

在最后一步，它显示如下错误：

我的实验机是64位的Ubuntu 18.04。

Answer 1

根据Makefile，不支持内核4.X。支票将uname -r与版本模式2.4% 2.5% 2.6% 3%进行比较：

SUPPORTED_OS_VERSION = 2.4% 2.5% 2.6% 3%
OS_VERSION := $(shell uname -r)
EMPTY_IF_NOT_SUPPORTED = $(filter $(SUPPORTED_OS_VERSION),$(OS_VERSION))

您可以尝试使用DISABLE_HOTSPOT_OS_VERSION_CHECK选项进行构建，看看会发生什么，但是降级到Kernel 3.X更安全。如果您要构建旧的JDK 8，则可以启动具有某些旧发行版的虚拟机，例如Fedora 9 with gcc 4.3.0 as per Supported Build Platforms。
