Java 1.8.0_311 on Solaris 9 returns 重定位错误，未找到符号 unsetenv 和 sema_timedwait

Question

这类似于this question about Java 1.6。作为该问题的 OP，我在 SPARC v9 架构（物理 SUN Fire V445）上有一个 Solaris：

-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 让我得到这个：

-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

仔细观察libjvm.so，不仅缺少unsetenv:

我假设timedwait信号量应该由librt实现，但它不是：

-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

看来，我被困在这里了，因为那是那台机器上唯一可用的 librt.so。有人知道如何让它工作吗？（我知道，sunos5.9 是一个垂死的平台，但 Oracle 仍在为该平台分发，我只是希望在那里也能使用它。）

谢谢！

您需要将系统升级到更高版本的 Solaris。 Java 8 is not supported on Solaris 9:

System Requirements

This version of the JDK is supported on the Oracle Solaris 10 Update 9 or later OS, Oracle Solaris 11 Express OS, and Oracle Solaris 11 OS. ...

Solaris 9 没有 unsetenv() 功能。 basic library functions documented in the Solaris 9 man page only lists the following u*() functions:

U

ualarm(3C)- schedule signal after interval in microseconds
ulckpwdf(3C)- manipulate shadow password database lock file
ulltostr(3C)- string conversion routines
ungetc(3C)- push byte back into input stream
ungetwc(3C)- push wide-character code back into input stream
unlockpt(3C)- unlock a pseudo-terminal master/slave pair
unordered(3C)- determine type of floating-point number
updwtmp(3C)- user accounting database functions
updwtmpx(3C)- user accounting database functions
usleep(3C)- suspend execution for interval in microseconds
utmpname(3C)- user accounting database functions
utmpxname(3C)- user accounting database functions

Solaris 9 中唯一的环境处理函数是putenv():

NAME

putenv- change or add value to environment

SYNOPSIS

#include <stdlib.h>

int putenv(char *string);

同样，"S" section of the Threads and Realtime Library Functions man pages section 3 documentation中没有sema_timedwait():

S

   .
   .
   .
sem_unlink — remove a named semaphore ( Index Term Link )
sem_wait — acquire or wait for a semaphore ( Index Term Link )
sema_destroy() — destroy a semaphore ( Index Term Link )
sema_init() — initialize a semaphore ( Index Term Link )
sema_post() — increment a semaphore ( Index Term Link )
sema_trywait() — decrement a semaphore ( Index Term Link )
sema_wait() — decrement a semaphore ( Index Term Link )
semaphore ...

Java 1.8.0_311 on Solaris 9 returns 重定位错误，未找到符号 unsetenv 和 sema_timedwait
