本文详细介绍了如何从源码安装QT 4.5.1版本的过程，包括下载、解压、配置环境变量等步骤，并提到了使用QT Creator进行项目的构建。

These days I have a task about building a GUI for SFTP(one ftp software built ourselves).

So I choose QT and learn to use it: )

First, download the tarball "qt-x11-opensource-src-4.5.1.tar.gz" & "qt-creator-1.1.0-src.zip"

Second, tar and install the qt-x11 as follow:

tar -xzvf qt-x11-opensource-src-4.5.1.tar.gz cd qt-x11-opensource-src-4.5.1.tar.gz ./configure --prefix=/usr/local/qt (if you choose the root dir, you should type 'sudo' while make and make install) sudo make sudo make install

Third, set qt environment var at .profile

QTDIR = /usr/local/qt PATH = $QTDIR/bin:$PATH MANPATH = $QTDIR/man:$MANPATH LD_LIBRARY_PATH = $QTDIR/lib:$LD_LIBRARY_PATH export QTDIR PATH MANPATH LD_LIBRARY_PATH

Up to now, we can use command 'qmake -project' and 'qmake' to create a Makefile of QT project and make it. Next I will show you how to install and use qt-creater, bye : )
