一、系统环境（OS X与XCode）
操作系统：Mac OS X Lion 10.7.4(11E53)
编程工具：Xcode 4.4.1(1448)，并装好了它的“Command Line Tools”。
安装过程可参考这些帖子——
在virtualbox上安装Mac OS X Lion 之 配置过程

http://www.crifan.com/install_xcode_for_mac_on_virtualbox/
Mac OS X Lion下找不到GCC
http://blog.csdn.net/qinjienj/article/details/7456193
二、尝试GTK+官网方法
对于mac系统，官网上主要是以下这几个页面——
Download for Mac OS X
http://www.gtk.org/download/macos.php
Building GTK-OSX
https://live.gnome.org/GTK%2B/OSX/Building
Bundling
https://live.gnome.org/GTK%2B/OSX/Bundling
我按照上述说明装好了jhbuild和gtk-mac-bundler，但后面的就没看懂，不知道怎么装。
在网上搜索了很久，找不到该方法的安装经验文章。遂放弃。
三、尝试利用homebrew安装
在网上搜索了一下，发现有人推荐用homebrew安装gtk（http://www.haskell.org/haskellwiki/Gtk2Hs/Mac）。于是决定试试。
3.1 安装homebrew
homebrew的官网是 http://mxcl.github.com/homebrew/。官网上介绍了homebrew的安装方法，就是在终端上运行下面这条命令——
ruby <(curl -fsSkL raw.github.com/mxcl/homebrew/go)
该命令是ruby脚本。mac下不需要安装ruby解释环境，因为系统自带了。
安装好后，可以使用下列命令来检查homebrew版本，确认是否安装成功——
brew –v
3.2 尝试安装GTK+
先检查一下homebrew是否支持GTK+，在终端中输入“brew search gtk”，执行结果如下——
macmatoiMac:~ mac$ brew search gtk
gtk+ gtk-doc gtkglextmm gtkwave pygtkglext
gtk+3 gtk-gnutella gtkmm lablgtk
gtk-chtheme gtkglext gtksourceview pygtk
发现列表中有“gtk+”。于是在终端中输入“brew install gtk+”进行安装——
macmatoiMac:~ mac$ brew install gtk+
==> Installing gtk+ dependency: pkg-config==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/pkg-config-
等了很久，发现还是停在这一行。估计是因为SourceForge被墙了。放弃吧，按Ctrl+C终止。
四、尝试利用fink安装
又在网络中搜索了很久，发现有人推荐fink（http://blog.sina.com.cn/s/blog_465881ff0100lnjq.html）。于是我决定试试。
4.1 安装fink
fink的官网是 www.finkproject.org。
点击国旗切换到中文，点击“下载”链接转到下载页面。
因为OS X Lion是基于Intel处理器的，于是点击“Fink 0.9.0 二进制安装包 (Intel)”，下载“Fink-0.9.0-Intel-Installer.dmg”。
下载完成后，根据官网说明进行安装——
2.双击 "Fink-0.9.0-Installer.dmg" 文件装载磁盘映象，然后双击里面 "Fink 0.9.0 Installer.pkg" 程序。接着按照屏幕的提示进行操作。
3.在安装的最后阶段，会打开一个终端程序，pathsetup.command 脚本会被自动运行。在编辑你的 shell 配置文件前，会提示请求你的同意。当脚本运行完毕，关闭终端窗口以后，一切都安装就绪了！
4.如果在此过程中发生了什么错误，你可以尝试重新运行一次安装程序宗卷里面的 pathsetup.command 文件（需要在终端窗口里面运行）。
open /sw/bin/pathsetup.command （这个过程应该对你机器的每个帐号都运行一次：每个用户应该登录到自己的帐号运行一次 pathsetup.command 脚本）。
如果 pathsetup.command 产生了错误信息，请参考文档，尤其是《用户指南》里面的 2.3 “设置你的环境”。
可是在我的电脑上，在Pacifist上点击安装后，进度条跑完后并没有出现终端窗口。
于是我按照说明，打开终端，输入命令，结果报错——
macmatoiMac:~ mac$ open /sw/bin/pathsetup.command
The file /sw/bin/pathsetup.command does not exist.
找不到文件？将官网网页切换到英语，发现命令是“/sw/bin/pathsetup.sh”。原来是中文版没有更新。
于是在终端中输入该命令运行脚本。
脚本运行完之后。依照官网说明在终端中输入命令，结果报错——
macmatoiMac:bin mac$ fink scanpackages; fink index-bash: fink: command not found
关闭终端，再打开终端运行命令，还是报告“fink: command not found”。
关机，重启。打开终端运行命令，这回OK了——
macmatoiMac:~ mac$ fink scanpackages; fink index

Removing fink-buildlock-system-xfree86-manual-install-0-0 ...似乎没有装好。于是再运行了几次“fink install gtk+2”，结果还是输出类似信息。
观察了一下输出信息，似乎问题是出在检测不到XFree86版本——
could not determine XFree86 version number
五、解决fink的“could not determine XFree86 version number”错误
5.1 解决办法
在网上搜索了很久，尝试了不少办法，最后发现这个帖子的办法有效——
Interaction issue between XQuartz-2.6.0 and fink on Leopard.
http://finkers.wordpress.com/2011/02/06/375/
其大意是——在超级权限下编辑“/sw/lib/perl5/Fink/VirtPackage.pm”，找到这一行（大概是1736行）——
if (open (XBIN, "$xdir/bin/$binary -version -iokit 2>\&1 |")) {
将该行改为——
if (open (XBIN, "$xdir/bin/$binary -version 2>\&1 |")) {
5.2 具体操作
用文本编辑器打开“/sw/lib/perl5/Fink/VirtPackage.pm”，搜索“iokit”，找到了那一行——
因为不是超级权限，不能保存。于是我在Finder中将“/sw/lib/perl5/Fink/VirtPackage.pm”复制到home目录。
然后打开终端，运行chmod命令修改文件权限——
macmatoiMac:~ mac$ ls -l VirtPackage.pm-rw-r--r-- 1 mac staff 55588 6 27 2008 VirtPackage.pm
macmatoiMac:~ mac$ chmod go+w VirtPackage.pm
在文本编辑器中打开home目录下的VirtPackage.pm，删除“-iokit”，并保存。
现在VirtPackage.pm文件已经改好了，用chmod命令将文件权限改回来，再用sudo执行cp命令复制文件——
macmatoiMac:~ mac$ chmod go-w VirtPackage.pm
macmatoiMac:~ mac$ ls -l VirtPackage.pm-rw-r--r--@ 1 mac staff 55581 9 13 00:07 VirtPackage.pm
macmatoiMac:~ mac$ sudo cp VirtPackage.pm /sw/lib/perl5/Fink
Password:
macmatoiMac:~ mac$
六、装好GTK+2，并编译程序
6.1 直到能运行gtk-demo
现在再运行“fink install gtk+2”，发现能成功装上，但好像装的是运行环境，而不是开发版。于是使用“fink list”命令检索包列表，依次安装了这些东西——
fink install gtk+2fink install gtk+2-dev
fink install glib2-dev
fink install pkgconfig
详细操作过程——
操作过程
这时运行gtk-demo，发现能成功打开GTK的demo——
6.2 直到能运行pkg-config --cflags --libs gtk+-2.0
刚才似乎已经将pkgconfig装好了，于是我执行几条命令测试一下——
macmatoiMac:~ mac$ pkg-config --cflags --libs gl-I/usr/X11/include -L/usr/X11/lib -lGL
macmatoiMac:~ mac$ pkg-config --cflags --libs gtk+-2.0Package pangoxft was not found in the pkg-config search path.
Perhaps you should add the directory containing `pangoxft.pc'to the PKG_CONFIG_PATH environment variable
Package 'pangoxft', required by 'GDK', not found发现gl库成功了，而gtk+-2.0库失败了。
最开始怀疑是$PKG_CONFIG_PATH路径配置问题，但配置后还是不行——
macmatoiMac:~ mac$ echo $PKG_CONFIG_PATH
macmatoiMac:~ mac$ PKG_CONFIG_PATH=/sw/lib/pkgconfig:$PKG_CONFIG_PATH
macmatoiMac:~ mac$ echo $PKG_CONFIG_PATH/sw/lib/pkgconfig:
macmatoiMac:~ mac$ pkg-config --cflags --libs gtk+-2.0Package pangoxft was not found in the pkg-config search path.
Perhaps you should add the directory containing `pangoxft.pc'to the PKG_CONFIG_PATH environment variable
Package 'pangoxft', required by 'GDK', not found
于是怀疑是缺少pangoxft，执行“fink list pangoxft*”。但找不到——
macmatoiMac:~ mac$ fink list pangoxft*UNIVERSAL->import is deprecated and will be removed in a future perl at /sw/lib/perl5/Fink/Checksum.pm line 27Information about 2548 packages read in 2 seconds.
macmatoiMac:~
然后再查查gdk——
macmatoiMac:~ mac$ fink list gdk*UNIVERSAL->import is deprecated and will be removed in a future perl at /sw/lib/perl5/Fink/Checksum.pm line 27Information about 2548 packages read in 0 seconds.
gdk-pixbuf 0.22.0-13 Image loading and manipulation library
gdk-pixbuf-s... 0.22.0-13 Image loading and manipulation library
发现有gdk-pixbuf，于是执行命令“fink install gdk-pixbuf”进行安装。
装好gdk-pixbuf后，执行“pkg-config --cflags --libs gtk+-2.0”，结果还是报错——
macmatoiMac:~ mac$ pkg-config --cflags --libs gtk+-2.0Package pangoxft was not found in the pkg-config search path.
Perhaps you should add the directory containing `pangoxft.pc'to the PKG_CONFIG_PATH environment variable
Package 'pangoxft', required by 'GDK', not found
想起GTK+中有一个库叫“pango”，是不是它呢——
macmatoiMac:~ mac$ fink list pango*UNIVERSAL->import is deprecated and will be removed in a future perl at /sw/lib/perl5/Fink/Checksum.pm line 27Information about 2548 packages read in 1 seconds.

装好pango1-dev后，执行“pkg-config --cflags --libs gtk+-2.0”，又有报错，但内容不同——
macmatoiMac:~ mac$ pkg-config --cflags --libs gtk+-2.0Package atk was not found in the pkg-config search path.
Perhaps you should add the directory containing `atk.pc'to the PKG_CONFIG_PATH environment variable
Package 'atk', required by 'GTK+', not found
根据前面的经验，查找atk，并安装atk1——
macmatoiMac:~ mac$ fink list atk*UNIVERSAL->import is deprecated and will be removed in a future perl at /sw/lib/perl5/Fink/Checksum.pm line 27Information about 2548 packages read in 1 seconds.
atk1 1.12.4-2 Accessability Toolkit
i atk1-shlibs 1.12.4-2 Accessability Toolkit
macmatoiMac:~ mac$ fink install atk1
……
装好atk1后，执行“pkg-config --cflags --libs gtk+-2.0”，终于正确输出了——

6.3 编译GTK+程序
写一个GTK+的简单的测试程序（testgtk.c），将它放在home目录。代码如下——
#include <gtk/gtk.h>int main (int argc, char *argv[])
{
GtkWidget *window;
gtk_init(&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL); /* quit*/ g_signal_connect(G_OBJECT(window),"delete_event",G_CALLBACK(gtk_main_quit),NULL);
gtk_window_set_title(GTK_WINDOW(window),"Hello GTK+!");
gtk_widget_show(window);
gtk_main ();
return 0;
}在终端上执行“gcc testgtk.c -o testgtk `pkg-config --cflags --libs gtk+-2.0`”开始编译，结果报错——

collect2: ld returned 1 exit status 看到“x86_64”，想到OS X Lion是64位系统，而fink安装的GTK+很可能是32位。
于是给gcc加上“-m32”参数，成功通过编译，并能正常运行——
macmatoiMac:~ mac$ gcc -m32 testgtk.c -o testgtk `pkg-config --cflags --libs gtk+-2.0`
macmatoiMac:~ mac$ file testgtk
testgtk: Mach-O executable i386
macmatoiMac:~ mac$ ./testgtk
