终于安装好了qt-x11-opensource-src-4.1.2.，现将安装说明公布 [复制链接]

这个问题XChinux 大哥有说明的，可是我看的不是很懂，弄了几天才弄好，这个适合菜鸟级的，只要英语不是很差就可以了，我英语太差劲，就不 翻译了。
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－英文原版如下：
                INSTALLING Qt/X11 Version 4.1.2.
1. If you have the commercial edition of Qt, install your license
  file as $HOME/.qt-license.
  For the open source version you do not need a license file.
2. Unpack the archive if you have not done so already:下载文件后解压缩，如果已己解压缩，直接进行步骤3
    cd /tmp ＃进入QT文件夹，这里是在TMP下
    gunzip qt-x11-opensource-src-4.1.2.tar.gz     # uncompress the archive
    tar xvf qt-x11-opensource-src-4.1.2.tar       # unpack it
  This creates the directory /tmp/qt-x11-opensource-src-4.1.2 containing the files
  from the archive. We only support the GNU version of the tar
  archiving utility. Note that on some systems it is called gtar.
3. Building
  To configure the Qt library for your machine type:
    cd /tmp/qt-x11-opensource-src-4.1.2 ＃进入安装文件包将TMP换为你的QT安装文件所在目录
    ./configure ＃不懂，复制后，回车//熟悉类Unix系统下软件开发、安装的人一般都知道的，这是一个shell脚本程序，为软件安装测试当前系统的一些必要的配置信息，如果这一步最后给出的信息说明未通过，那么就不能进行下一步的编译工作。
  Type "./configure -help" to get a list of all available options.
  To create the library and compile all the demos, examples, tools,
  and tutorials, type:建立和编辑所有图书   游行、实例、工具   并辅导、类型:
    make   ＃不懂，复制后，回车//make命令依据Makefile中的规则开始编译
  To install the library, demos, examples, tools, and tutorials,
  type:
    su -c "make install" ＃同上//这个命令包含两个步骤，就是取得可安装的权限使用make install进行安装已编译好的文件(install是Makefile里的一个目标，make install就是执行为达到此目标而在Makefile中制定的规则)
  and enter the root password. Qt is by default installed into
  /usr/local/Trolltech/Qt-4.1.2 but this can be changed by using
  the -prefix parameter.//这里说明了，取得root权限，Qt默认安装在/usr/local/Trolltech/Qt-4.1.2，但是你可以使用-prefix参数来自定义安装路径
  Note that on some systems the make utility is called differently,
  e.g. gmake. The configure script tells you which make utility to
  use.
4. Environment variables
  In order to use Qt, some environment variables needs to be
  extended.
    PATH           - to locate qmake, moc and other Qt tools
  This is done like this:
  In .profile (if your shell is bash, ksh, zsh or sh), add the
  following lines:
    PATH=/usr/local/Trolltech/Qt-4.1.2/bin:$PATH
    export PATH
  In .login (in case your shell is csh or tcsh), add the following line:
    setenv PATH /usr/local/Trolltech/Qt-4.1.2/bin:$PATH
  If you use a different shell, please modify your environment
  variables accordingly.
  For compilers that do not support rpath you must also extended the
  LD_LIBRARY_PATH environment variable to include
  /usr/local/Trolltech/Qt-4.1.2/lib. On Linux with GCC this step
  is not needed.
5. That's all. Qt is now installed.
  If you are new to Qt, we suggest that you take a look at the demos
  and examples to see Qt in action. Run the Qt Examples and Demos
  either by typing 'qtdemo' on the command line or through the
  desktop's Start menu.
