Solaris 9 上的 Java 1.8.0_311 返回重定位错误，未找到符号 unsetenv 和 sema_timedwait

Question

这类似于 这个关于Java 1.6的问题。作为该问题的OP，我有一个基于 SPARC v9 架构的 Solaris（物理 SUN Fire V445）：

-bash-4.4$ cat /etc/release 
                      Solaris 9 9/05 HW s9s_u9wos_06b SPARC
           Copyright 2006 Sun Microsystems, Inc.  All Rights Reserved.
                        Use is subject to license terms.
                           Assembled 25 September 2006
-bash-4.4$ isainfo -v
64-bit sparcv9 applications
32-bit sparc applications

从最新的 Oracle 分布式 Java 8 for SPARC 64 位调用 java 得到了这个：

-bash-4.4$ /usr/jdk/instances/jdk1.8.0_311/bin/java -version
Error: dl failure on line 893
Error: failed /export/home1/java/instances/jdk1.8.0_311/jre/lib/sparcv9/server/libjvm.so, because ld.so.1: java: fatal: relocation error: file /export/home1/java/instances/jdk1.8.0_311/jre/lib/sparcv9/server/libjvm.so: symbol unsetenv: referenced symbol not found

更仔细地查看 libjvm.so，不仅缺少 unsetenv：

我认为 timedwait 信号量应该由 librt 实现，但事实并非如此：

-bash-4.4$ nm -gD /usr/lib/64/librt.so | grep sema
                 w _libthread_sema_wait
                 U _lwp_sema_init
                 U _lwp_sema_post
                 U _lwp_sema_trywait
                 U _lwp_sema_wait
                 U sema_destroy
                 U sema_init
                 U sema_post
                 U sema_trywait
                 U sema_wait

似乎，我被困在这里，因为这是唯一的 librt.so在那台机器上可用。有人知道如何让它发挥作用吗？ （我知道，sunos5.9是一个垂死的平台，但 Oracle 仍然为该平台进行分发，我只是希望在那里使用它。）

谢谢！

您需要将系统升级到更高版本的 Solaris。 Solaris 9 不支持 Java 8 :

系统要求

Oracle Solaris 10 Update 9 支持此版本的 JDK
或更高版本的操作系统、Oracle Solaris 11 Express 操作系统和 Oracle Solaris 11 操作系统。
...

Solaris 9 没有 unsetenv() 函数。 Solaris 9 man 中记录的基本库函数页面仅列出了以下u*()函数：

你

ualarm(3C) - 在微秒间隔后调度信号
ulckpwdf(3C)-操作影子密码数据库锁定文件
ulltostr(3C) - 字符串转换例程
ungetc(3C) - 将字节推回输入流
ungewc(3C) - 将宽字符代码推回输入流
unlockpt(3C)-解锁伪终端主/从对
unordered(3C)-确定浮点数的类型
updwtmp(3C)-用户记帐数据库函数
updwtmpx(3C)-用户记帐数据库函数
usleep(3C) - 暂停执行一段时间（以微秒为单位）
utmpname(3C)-用户记帐数据库函数
utmpxname(3C)-用户记帐数据库函数

Solaris 9 中唯一的环境处理函数是 putenv( ）：

姓名

putenv- 改变或增加环境的价值

概要

#include ;

int putenv(char *字符串);
