扩展Perl正在打破动态加载

Question

我正在尝试将XS编译成perl [ed(ikegami):也就是说他正在使用:: MakeMaker make perl来创建一个perl静态链接的C供应商库]但是当我这样做时,新版本的perl不支持动态加载模块.每当我尝试运行类似use Socket(或任何其他模块)的perl代码时,我得到:

Can't load module Socket, dynamic loading not available in this perl.

是否有编译器/链接器开关我设置不正确或什么？所有这些都是在1998年和2004年在另一个盒子(PA-RISC上的hpux旧)上编译的,但是我们正在转向一个新的盒子(hpux11 itanium)而且我正在撞墙.

这是我的Makefile.PL:

use ExtUtils::MakeMaker;
# See lib/ExtUtils/MakeMaker.pm for details of how to influence
# the contents of the Makefile that is written.
WriteMakefile(
    'NAME'      => 'Udtutil',
    'VERSION_FROM' => 'Udtutil.pm', # finds $VERSION
    'LIBS'      => '-L/usr/ud/PFUSION/Udtutil -L/usr/ud/lib -lapidummy ' .
                   '-lshare -ludsql -ludmach -lbasic ' .
                   '-lperf -lret1 -lides -lpipe -lfunc -lndx -lrep -lshm ' .

                   '-ldld ' .
                   '-lnfaclnt -lodsdummy -lcl ' .
                   '-lCsup -lcl -lelf -lm -lcurses -lsec -lpam ',
    'INC'       => '-I/usr/ud/include',     # e.g., '-I/usr/include/other' 
    'OPTIMIZE'  => '-O -Ae +DD64 -q -z +u4 -w ',
    'LINKTYPE'  => 'dynamic',
    'OBJECT'    => '$(BASEEXT)$(OBJ_EXT) funchead.o interfunc.o callcf.o efs_init.o',
);

当我跑步时perl Makefile.PL,一切看起来都很好:

> perl Makefile.PL
Checking if your kit is complete...
Looks good
Writing Makefile for Udtutil
Writing MYMETA.yml

当我运行make或make perl一切顺利时,它会创建一个新的本地perl二进制文件.

但是,当我执行时./perl mytest.pl,如果mytest.pl*使用*s任何模块,我得到:

Can't load module Socket, dynamic loading not available in this perl.

关于如何编译这个新的perl并仍然保持动态加载工作的任何建议？

我不知道我收集并保存的这封电子邮件是否有任何有用的信息，作为 Perl 的 DBD::Informix 模块的背景信息的一部分。

I have succeeded in building a perl with DBD:Informix that uses dynamic
loading for everything except DBD:Informix and DBI.  I got a runtime error of
not being able to find the symbol of boot_DBI if DBI was also not
statically built into perl.  Here is a short discription of what I did.

1)  Built perl 5.004_2 normally.
2)  Installed perl.
3)  Built DBI statically (make static).
4)  Installed DBI (make install).  This is not just the install of the perl
    binary, since DBI.a is needed later.
5)  Changed DBD Makefile.pl to call esql -static and esql -static -libs
    instead of esql and esql -libs.
6)  Created DBD Makefile using perl Makefile.PL.
7)  Built DBD statically (make static and make perl, etc.)
8)  The make test_static failed, due to wanting to create a dynamic object
    (Informix.sl failed due to trying fixup a symbol)
9)  Installed with make -k install to get pass error creating Informix.sl,
    while still installing Informix.pm (could not find a special install
    for static perl.
10) Installed new perl executable.  It seems to work after some initial
    test.

我当时注意到 Kent 一定是在 HP-UX 上构建的，因为引用了 Informix.sl。我认为这里没有什么用处，但这是我关于构建 Perl 静态链接版本的唯一额外信息。正如你所看到的，它已经接近15岁了。

我想知道 Perl 5.14.x 是否仍然完全支持和测试静态链接模块？
