1. 运行命令cabal install glib时出现错误：
Cannot find gtk2hsC2hs
Please install `gtk2hs-buildtools` first and check that the install directory is in your PATH (e.g. HOME/.cabal/bin).
2. 运行命令cabal install gtk2hs-buildtools
Installed gtk2hs-buildtools-0.12.5.2
3. 重新运行命令cabal install glib，出现新的错误：
The program pkg-config version >=0.9.0 is required but it could not be found.
4. 下载/安装GTK+ all-in-one bundle
a) 下载网址：http://www.gtk.org/download/win32.php，直接下载链接：http://win32builder.gnome.org/gtk+-bundle_3.6.4-20130921_win32.zip。
b) 下载后，解压至一个文件夹，比如F:\GTK，并将该文件夹路径添加至PATH环境变量中
setx /M PATH "%PATH%;F:\GTK"
5. 重新运行命令cabal install glib，出现新的错误：
The pkg-config package glib-2.0 is required but it could not be found.
6. 运行命令pkg-config --modversion glib-2.0，出现错误：
ackage glib-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `glib-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'glib-2.0' found
7. 在F:\GTK中添加glib-2.0.pc文件，文件内容如下：
prefix=F:\GTK
exec_prefix=F:\GTK
libdir=F:\GTK
includedir=F:\GTK glib_genmarshal=glib-genmarshal
gobject_query=gobject-query
glib_mkenums=glib-mkenums Name: GLib
Description: C Utility Library
Version: 2.0
Libs: -L${libdir} -lglib-2.0
Cflags: -I${includedir}/glib-2.0 -I${libdir}/glib-2.0/include
8. 重新运行命令cabal install glib，又出现新的错误：
The pkg-config package gobject-2.0 is required but it could not be
found.
在F:\GTK中添加gobject-2.0.pc文件
9. 重新运行命令cabal install glib，又出现新的错误：
Missing dependencies on foreign libraries:
* Missing C libraries: glib-2.0, gobject-2.0
This problem can usually be solved by installing the system packages that
provide these libraries (you may need the "-dev" versions). If the libraries
are already installed but in a non-standard location then you can use the
flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are.
就研究到这个地方，问题未得到解决。。。
