perl - 为 OS X 构建 Perl - 架构特定的编译选项

Question

感谢 Chas. Owens 的建议, 我玩得很开心Perlbrew在我的主目录中有各种 Perl 版本。然而，我的问题更普遍地是关于在 OS X 下构建更新的 Perl。

我在最近的 MacBook Pro 上运行 OS X 10.6.4 Snow Leopard。经过small diversion在 Snow Leopard 下正确设置 gcc，我已经使用默认选项在我的主目录中构建并运行了 Perl 5.12.1。它通过了 Perl 测试工具。

Perlbrew 允许使用特定于操作系统和平台的标志来构建 Perl。这些是 Perl 配置脚本的 -D -U -A 选项。 perlmacosx自述文件已 4 年未更新，因此不再有用。

我很想模仿 Apple 在系统 Perl v 5.10.0 中使用的开关(您可以通过键入 [path_to_specific_perl]/perl -V 或 来查看您的特定 Perl/usr/bin/perl 在大多数情况下用于系统......)除了 -Dprefix=/usr 对于新的 Perl 构建的不同根目录会有所不同，还有什么我应该使用吗？

(目测)以下是 Apple 编译选项和默认选项之间的主要区别:

config_args:
Apple:       -ds -e
Default:     -de

-D: =======================
Apple:       useithreads=define, usemultiplicity=define
Default:     useithreads=undef, usemultiplicity=undef

Compiler: =================
Apple:       optimize='-Os' 
Default:     optimize='-O3'

Apple:       -arch x86_64 -arch i386 -arch ppc
Default:     none specified

Apple:      -g -pipe
Default     these optimizations are not set

Apple       not set
Default     -no-cpp-precomp

Linker: ================
Apple:     useshrplib=true, libperl=libperl.dylib
Default:   useshrplib=false, libperl=libperl.a

Characteristics of libperl: =============
Apple      MULTIPLICITY PERL_IMPLICIT_CONTEXT USE_ITHREADS USE_REENTRANT_API
Default    PERL_MALLOC_WRAP USE_PERL_ATOF

另一个区别是 Apple Perl libperl 是一个动态加载器，默认构建是静态链接的。

所以，问题:

1. 我应该使用哪个 -D -U -A 开关在 OS X 10.6+ 上构建 Perl 的本地副本？我不认为我需要像 Apple 版本那样的胖二进制文件，而且我不知道我是否应该做一个 dynaloader 版本。主要是我在寻找建议的优化开关和生成的 libperl 的建议特征。
2. 我应该做一个 dynaloader 版本吗？ (即，在 OS X 意义上的 Dynamic Libraries ...)
3. Perl 系统是/usr/bin/perl，我不想更改它。我是否将脚本中的 sheebang 更改为指向 Perl 的 Perlbrew 版本？这意味着我的 sheebang 将是“/Users/andrew/perl5/perl”。我要改变我的路径指向那里吗？其他人在这方面做了什么？什么是“最佳实践”？
4. 当我运行 Perlbrew 时，我收到警告 v-string in use/require non-portable at ./perlbrew line 818。 Perlbrew 中的第 818 行是 use 5.8.0; 该行不应该是 use 5.008_000 吗？

编辑

感谢 Jonathan Leffler，我至少有一些 Perls 可以看。我没有深入研究它，而是在大多数情况下采用默认设置，添加线程，它似乎工作正常。现在我已经安装了 Perlbrew 和几个 Perl，并且我将系统 Perl 保留在 5.10。我在 sheebang 上使用 /usr/bin/env perl 来获得面向 future 的代码。

Answer 1

我能提供的最好的是“perl -V”的输出，用于我的每个 5.1x 版本 Perl 的自制程序集合 - 一些 32 位，一些 64 位。我省略了 PowerPC 构建(从我拥有 Intel Mac 之前的日子开始)。

drwxr-xr-x  8 jleffler  staff       272 Aug  1  2009 v5.10.0
drwxr-xr-x  8 jleffler  staff       272 Nov  8  2009 v5.10.1
drwxr-xr-x  6 jleffler  staff       204 Oct 26  2009 v5.10.1-64
drwxr-xr-x  6 jleffler  staff       204 Jun 23 09:36 v5.12.1
drwxr-xr-x  5 jleffler  staff       170 Jun 17 21:14 v5.12.1-32bit
drwxr-xr-x  5 jleffler  staff       170 Aug 30 15:02 v5.13.4

我不使用线程或多重性进行构建。我确实使用动态加载进行构建；我使用 dlopen 版本 - 这是默认建议的。机器根据连接到网络的位置获得不同的名称；这显示在构建机器名称中。
