Perl单步调试--在公司代理proxy下，安装WIN32版Padwalker

PadWalker安装起来比较费劲，又因为官方网站上写的是ActivePerl 的PPM 5.10 是对Padwalker支持都是FAILLED
所以需要安装一个自己编译的版本，步骤比较多

1.首先安装Win32 的 Activeperl, 下载地址是: http://www.activestate.com/Products/activeperl/index.mhtml
   因为有代理，所以设定PPM的代理也不方便，可以通过CPAN 直接安装和设定，配置过程如下：


C:/>perl -MCPAN -eshell
CPAN: File::HomeDir loaded ok (v0.69)

cpan shell -- CPAN exploration and modules installation (v1.9205)
ReadLine support enabled

cpan> o conf http_proxy
    http_proxy         [http:://153.88.253.16:80]
Type 'o conf' to view all configuration items


cpan> o conf http_proxy 153.88.253.16:80
    http_proxy         [153.88.253.16:80]
Please use 'o conf commit' to make the config permanent!


cpan> o conf commit
commit: wrote 'C:/Perl/lib/CPAN/Config.pm'

cpan> update



但是很可能你是安装不上，主要是因为WINDOWS的目录分隔符是使用的"/"; 当是我就是，使用现成的PPM包，也是报错，
所以就开始使用源码安装,源码的下载地址是：http://search.cpan.org/src/ROBIN/


安装的过程要求你额外的安装工具，如下

MinGW，下载地址是：http://sourceforge.net/projects/mingw/

msys，  下载地址是：http://downloads.sourceforge.net/mingw/MSYS-1.0.10.exe

安装方法初步很简单，我会在另外的文章里面总结

注意安装完成msys后，进行如下的配置：
/etc/fstab 文件如下：

# /etc/fstab
#C:MinGW /mingw
C:/MinGW /mingw
C:/Perl  /perl
C:/Tcl   /tcl

这样就可以直接在msys的终端下使用 perl tclsh85 gcc make 等等开源工具了

因为一般的perl代码包的安装步骤如下

1. perl Makefile.pl
2. make
3. make test
4. make install

所以我们需要使用make, 我也不知道为什么windows里面使用msys的make不太好用，决定使用MS在Visual Studio里面的nmake工具，

nmake下载地址： http://download.microsoft.com/download/vc15/patch/1.52/w95/en-us/nmake15.exe

下载后，把nmake15.exe复制到目录
"C:/WINNT"-->(2000)或者" C:/WINDOWS"-->(XP)下面，并且重命名为：nmake.exe
就可以直接在CMD里面使用了，如果看到如下，那么就说明nmake正常：

C:/>nmake

还需要安装一个math的lib库--"Math-BigInt-FastCalc-0.19"
下载地址是：
http://search.cpan.org/~tels/Math-BigInt-FastCalc-0.19/lib/Math/BigInt/FastCalc.pm

准备工作已经完成，现在正式进行Padwalker的安装，在msys的终端下面，运行步骤如下，请读者自己观看，这里就不赘述了：

然后在建立文件C://test.pl，来测试一下安装的模块是否成功，文件如下：

# perl  padwalker.pl
#!/usr/bin/perl

use strict;
use PadWalker qw(peek_my peek_our peek_sub closed_over);

sub increment_my_x {
    my $h = peek_my (1);
    ${$h->{'$x'}}++;
}

my $x=5;

increment_my_x;

print $x;  # prints 6


然后运行，如果看到结果如下，那么恭喜你，你安装成功了！
