我在我的 Ubuntu 10.04 机器上安装了 ActivePerl 5.10.1.1007。我有一个非常简单的 Perl 脚本，其中包含以下几行：

use lib "/opt/ActivePerl-5.10/lib";
use Tcl;

my $Interpreter = new Tcl;

$Interpreter->Eval('puts "Hello world"');

$Interpreter->Eval('set ::env(TESTVAR) 55')

输出如下：

$ /opt/ActivePerl-5.10/bin/perl5.10.1 simple.pl
Hello world

请帮忙。我找不到使这项工作的方法。设置非环境变量不会导致崩溃。例如：

 $Interpreter->Eval('set localvar 55')

谢谢！！！

第一阶段分析：退出时内存损坏。我想说，关于谁应该释放块以及如何释放块存在交战。现在我们深入挖掘……</p>

您可能会看到 Perl 和 Tcl 都在独立尝试解决错误环境变量的系统实现中的错误功能。特别是，C 库存setenv()在许多内存泄漏问题，这使得它比您可能天真的期望的更不切实际；我非常希望 Perl 能够解决这个问题，而且我知道Tcl 也可以，但这确实意味着只有一种语言应该设置环境变量，并且在这种情况下几乎肯定需要是 Perl（根据你的证据'已经提出）。

你真的需要从你的 Tcl 代码中设置环境变量吗？如果你不能这样做，那将是最简单的方法。:-) 否则，我们谈论的是构建不同的 Tcl（以便它要求 Perl 端进行内存管理）或做一些魔术来断开 Tcl 端与真实环境的连接。您可能还想将问题上游报告给 ActiveState。

我会继续挖掘，如果我找到解决方案，我会告诉你的。我将此报告给 ActiveState。内联是我的电子邮件和他们的回复，但总结一下：

1. They didn't develop "Inline Tcl" for Perl nor did they test it.
2. It was developed in 2001 and no additions were made to it since then.
3. When it was developed (in 2001), it was marked as "alpha" and no additions were made since then.



Hi Mircea,

Inline::Tcl is not part of ActivePerl. It's not tested with ActivePerl, and it
does not build on our PPM build farm against ActivePerl:
http://ppm4.activestate.com/i686-linux/5.10/1000/R/RR/RRS/Inline-Tcl-0.09.d/log-20090614T112213.txt

Offhand, the error message looks like a compiler mismatch problem, but it could be
almost anything since Inline::Tcl hasn't been touched by the author since 2001,
and even then the release notes describe it as "alpha software". It doesn't seem
to like Linux very much any more:
http://matrix.cpantesters.org/?dist=Inline-Tcl%200.09;maxver=1
Hmm.. The author's home page is 404. You should probably find another way to do it.

你不应该需要这条线：use lib "/opt/ActivePerl-5.10/lib"; 除非你有一个错误的配置。您可能想从轨道上取消安装并重新开始。

您使用 ActivePerl 有什么特别的原因吗？您应该能够简单地从源代码安装 perl - 您使用的是真正的操作系统，所以我会利用它:)
