如何在编译Perl的DBD :: mysql时修复“Symbol not found：_is_prefix”？

Question

首先，我想构建DBD::mysql包。这一直没有成功，因为无论如何造成的结果都无法通过Symbol not found: _is_prefix加载测试。所以我认为cpan可能有点旧了。我知道这是一个随机假设，但cpan确实告诉我要安装最新的Bundle::CPAN。

谁在Mac OS X 10.5上成功安装DBD::mysql或Bundle::CPAN？你能推荐任何我可以做得不同的事情吗？

This is perl, v5.8.8 built for darwin-thread-multi-2level 
(with 4 registered patches, see perl -V for more detail)

/usr/local/mysql/bin/mysql Ver 14.14 Distrib 5.1.36, 
for apple-darwin9.5.0 (i386) using readline 5.1

下面是DBD::mysql日志的输出CPAN的：

Answer 1

好吧，如果你得到这些错误，我现在了解以下内容：

1. MySQL 5.1 for Mac OS X x86_64不与DBD::mysql（还）不兼容。安装32位x86版本，然后重试。你会成功。我希望perl Makefile.pl只会在横幅上告诉你。
2. Bundle::CPAN有问题，因为我没有以root身份进行安装。为什么这使得它报告循环引用，而不是安装许可问题，我永远不会明白。

如果此时变成过时的信息，请添加注释。

Answer 2

你尝试安装Bundle::DBD::mysql？

Answer 3

我还没有处理这个问题，但我发现MacPorts清理了我所有的UNIX不兼容问题。在忍受太多的痛苦和痛苦之前，你可能想尝试一下。

Answer 4

它在哪里抱怨循环依赖？它看起来像你试图链接到一个不兼容的版本的MySQL库。它正在查找的符号不在您加载的库中。我不认为这是由CPAN.pm或cpan脚本引起的问题。

一些问题：

• 谁编的Perl？这是苹果的Perl吗？
• 谁编译mysql？这是你自己的版本，因为它在/ usr/local？
• 您以前编译过其他版本吗？我从编译开始，确保一切都指向正确的位置。

Answer 5

安装可从其开发人员网站获得的（测试版）5.4.1 64位版本的mysql可以解决此问题。经过雪豹测试。

Answer 6

在我的电脑上安装最新的beta版64bit版本的Mysql固定问题。
