2.下载Qt 4.4.3。去这里下载：ftp://ftp.trolltech.com/qt/source/qt-win-opensource-4.4.3-mingw.exe 完成后安装。注意选了MinGW编译器位置之后安装程序会报错，不用管它，确定安装即可；

3.在环境变量的PATH中增加你的MinGW\bin和Qt\4.4.3\bin的详细位置；

4.Qt 4.4.3可能有些小bug，编译时会报错，所以需要修改以下一些文件：

(1) Qt\4.4.3\src\corelib\arch\qatomic_windows.h：找到第386-392行，应该是这样的：
extern “C” {
__declspec(dllimport) long __stdcall InterlockedCompareExchange(long *, long, long);
__declspec(dllimport) long __stdcall InterlockedIncrement(long *);
__declspec(dllimport) long __stdcall InterlockedDecrement(long *);
__declspec(dllimport) long __stdcall InterlockedExchange(long *, long);
__declspec(dllimport) long __stdcall InterlockedExchangeAdd(long *, long);
}
请改成这样：
extern “C” {
__declspec(dllimport) long __stdcall InterlockedCompareExchange(volatile long *, long, long);
__declspec(dllimport) long __stdcall InterlockedIncrement(volatile long *);
__declspec(dllimport) long __stdcall InterlockedDecrement(volatile long *);
__declspec(dllimport) long __stdcall InterlockedExchange(volatile long *, long);
__declspec(dllimport) long __stdcall InterlockedExchangeAdd(volatile long *, long);
}

(2) Qt\4.4.3\src\corelib\io\qfsfileengine_win.cpp：找到第67-68行，应该是这样的：
#define SECURITY_WIN32
#include <security.h>
请在这两行中间加上一行：#include <subauth.h>，使其像这样：
#define SECURITY_WIN32
#include <subauth.h>
#include <security.h>

(3) Qt\4.4.3\src\gui\inputmethod\qwininputcontext_win.cpp，找到第500行，应该是这样：
bool QWinInputContext::endComposition()
请在这行前面加上一行extern bool qt_sendSpontaneousEvent(QObject *, QEvent *);，使其像这样：
extern bool qt_sendSpontaneousEvent(QObject *, QEvent *);
bool QWinInputContext::endComposition()

5.OK， 现在应该可以编译了。点开始菜单中的“Qt by Nokia v4.4.3 (OpenSource)”->“Qt 4.4.3 Command Prompt”，然后输入“configure -debug-and-release -plugin-sql-sqlite -plugin-sql-odbc -qt-libpng -qt-libjpeg”回车进行configure，几分钟之后configure完成，再输入“mingw32-make”回车就可以编译了。编译可 能需要3个小时时间（我的电脑CPU是Intel Core Duo T7500的，内存是2G），大概需要4G空间。编译完成后，请输入“mingw32-make clean”清除中间文件，这样可以使占用空间减少到1.95G。

6.好了。请享用GCC 4.3.2和Qt 4.4.3带给你的快乐吧。

Not everyone likes to compile libcurl. It is very boring and time comsuming. Using a compiled libcurl can save some time. So I downloaded Win32 Generic libcurl compiled by Günter Knauf from http://curl.haxx.se/download.html . The link is http://www.gknw.net/mirror/curl/win32/curl-7.18.2-devel-mingw32.zip . I guess it is compiled by MinGW.

If you try to perl Makefile.PL and make, of course it would fail. So I change something in Makefile.PL.

1. Comment “requires_external_bin       'curl-config'“, that means add a “#”
before the line;
2. Comment /usr/include, /usr/local/curl/include, /usr/local/include/curl, ../../include, ../curl/include in “my @includes“;
3. Change “C:\\INCLUDE\\CURL” in “my @includes” to the directory like “E:\\Perldev\\downloader\\curl-7.18.2-devel-mingw32\\include“. E:\\Perldev\\downloader is the directory where you decompress the curl-7.18.2-devel-mingw32.zip to;
4. Comment “my $cflags = `curl-config --cflags`“, “my $lflags = `curl-config --libs`“, “my $libcurl_version = `curl-config --version`” and “print "version is $libcurl_version"“;
5. Add these lines to the place where step 4 does:

my $cflags = '-I"E:\\Perldev\\downloader\\curl-7.18.2-devel-mingw32\\include"';
my $ldflags = '-L"E:\\Perldev\\downloader\\curl-7.18.2-devel-mingw32\\lib"';
my $lflags = '-lcurl -lcurldll';

6. Comment these lines:

if (!defined($lflags)) {
$lflags="-lcurl";
# Windows version of libcurl - not widely tested, feedback welcome!
if ($^O eq 'MSWin32') {
foreach my $try (@includes) {
if (-f $try . '\lib\libcurl_imp.lib') {
$lflags = $try . '\lib\libcurl_imp.lib' unless(-f $lflags);
last;
}
}
$lflags="libcurl.lib" unless ($lflags);
}
print "Guessing your linker flags as: $lflags\n";
}

7. At the end of this file, please change “'LIBS'         =>$lflags”
to “'LIBS'         =>"$ldflags $lflags"“;
8. Save the file;
9. perl Makefile.PL;
10. nmake (you need nmake from Mircosoft, which can be downloaded from
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q132084 );
11. nmake install.

OK, it’s done.

use DBI;
use warnings;
use strict;
use utf8;
use bytes;

my $dbh = DBI->connect("DBI:mysql:database=yourdatabase;host=yourhost",
			"username", "password",
			{'RaiseError'=>1, 'mysql_enable_utf8'=>1})
			|| die "Cannot connect to database:".DBI->errstr;
my $sth=$dbh->prepare('SELECT * FROM onetable');
$sth->execute()||die "An error occurs while querying: ".$sth->errstr;
while(my @data=$sth->fetchrow_array()){
	for my $i(0..$#data) {
		print "$data[$i]\\t";
	}
	print "\\n";
}
$dbh->disconnect();

% $r->content_type('text/html; charset=UTF-8');

就可以了。

例如这是个最简单的index.html文件：
% $r->content_type('text/html; charset=UTF-8');
% my $planet = "世界";
你好，<% $planet %>！

1. 下载”Automated MinGW Installer” (http://sourceforge.net/project/showfiles.php?group_id=2435)，安装它。注意选上g++和mingw32-make；
2. 下载”GNU Source-Level Debugger” (http://sourceforge.net/project/showfiles.php?group_id=2435)，把它解压缩到您安装MinGW的地方。当解压软件你是不是覆盖同名文件时，一律选“否”；
3. 下载”Qt/Windows Open Source Edition” (http://trolltech.com/developer/downloads/qt/windows)。安装它；
4. 下载”Eclipse IDE for C/C++ Developers” (http://www.eclipse.org/downloads/)，把它解压缩到某个文件夹去。如果你已经有开发Java的Eclipse了，可以只安装cdt插件；
5. 下载”Qt Eclipse Integration Downloads” (http://trolltech.com/developer/downloads/qt/eclipse-integration-download)，安装它；
6. 设置系统的环境变量。这一步很重要。如果有什么地方没有正确完成的话，以后可能出现不少问题。E:\Develop是我安装MinGW的Qt地方。
把E:\Develop\MinGW\bin、E:\Develop\Qt\4.3.4\bin和E:\Develop\Qt\4.3.4\lib添加到Path；
把E:\Develop\MinGW\lib和E:\Develop\Qt\4.3.4\lib添加到Lib (如果没有Lib，请创建一个)；
把E:\Develop\MinGW\include和E:\Develop\Qt\4.3.4\include添加到Include (如果没有Include，请创建一个)；
重新启动计算机；
7. 在开始菜单\所有程序\Qt by Trolltech v4.3.4 (OpenSource)里，找到Qt 4.3.4 (Build Debug Libraries)，然后执行它。注意这需要2个小时时间，并且安装MinGW的分区需要3GB的空间；
8. 在Eclipse中编写一个Qt程序；
9. 点击臭虫图标，选”Open Debug Dialog…”在C/C++ Local Application添加一个新的配置，注意C/C++ Application那一栏里应该是”debug/*.exe”，而不是”release/*.exe”！点Debug选项卡，再把Debugger选择为gdb/mi，现在你应该可以debug了；
10. 终于完了。期望你不要再遇到这类问题。

注意，第6步非常重要。你必须在添加系统环境变量之后重启计算机。

我希望这份指南能帮助你。
