linux下安装QT的方法

1、下载qt_sdk安装???
2、命令安装(在线安装)
首先在命令行输入apt-get update
然后输入 apt-cache search qtcreator
然后输入 apt-get install qtcreator
3、下载QT的源码自己编译。
自己下载QT源码,如: qt-soruce-4.7.4.tar
在命令行输入 tar –xzvf qt-soruce-4.7.4.tar解压源码
然后参照http://wiki.qt.io/Building_Qt_5_from_Git这个网址的方法(见下面)
先安装QT的环境然后手动编译QT源码即可。
Qt for Linux/X11 - Building fromSource
You can download the Qt 5 sources from the Downloads page. For more information, visit the Getting Started with Qt page.
Qt for X11 has some requirements that are given in more detailin the Qt for X11 Requirementsdocument.
Step 1:Installing the License File (Commercial Editions Only)
If you have the commercial edition of Qt, install your licensefile as $HOME/.qt-license
.
For the opensource version you do not need a license file.
Step 2: Unpacking the Archive
Unpack the archive if you have not done so already. For example,if you have the qt-everywhere-opensource-src-%VERSION%.tar.gz
package, type the following commands at a command line prompt:
cd /tmp
gunzip qt-everywhere-opensource-src-%VERSION%.tar.gz # uncompress the archive
tar xvf qt-everywhere-opensource-src-%VERSION%.tar # unpack it
This creates the directory /tmp/qt-everywhere-opensource-src-%VERSION%
containing the files from the archive. We only support the GNUversion of the tar archiving utility. Note that on some systems it is calledgtar.
Step 3: Building the Library
To configure the Qt library for your machine type, run the ./configure
script in the package directory.
By default, Qt is configured for installation in the /usr/local/Qt-%VERSION%
directory, but this can be changed by using the -prefix
option.
cd /tmp/qt-everywhere-opensource-src-%VERSION%
./configure
The Configure Options page contains more information aboutthe configure options.
To create thelibrary and compile all the examples, tools, and tutorials, type:
make
If -prefix
is outside the build directory, you need to install the library,examples, tools, and tutorials in the appropriate place. To do this (as root ifnecessary), type:
make install
Note that onsome systems the make utility is named differently, e.g. gmake. The configurescript tells you which make utility to use.
Note: If you laterneed to reconfigure and rebuild Qt from the same location, ensure that alltraces of the previous configuration are removed by entering the builddirectory and typing makeconfclean
beforerunning configure
again.
Step 4: Set the Environment Variables
In order touse Qt, some environment variables needs to be extended.
PATH - to locate qmake, moc and other Qt tools
This is donelike this:
In .profile
(if your shell is bash, ksh, zsh or sh), add the followinglines:
PATH=/usr/local/Qt-%VERSION%/bin:$PATH
export PATH
In .login
(in case your shell is csh or tcsh), add the following line:
setenv PATH /usr/local/Qt-%VERSION%/bin:$PATH
If you use adifferent shell, please modify your environment variables accordingly.
For compilers that do not support rpath you must also extendedthe LD_LIBRARY_PATH
environment variable to include /usr/local/Qt-%VERSION%/lib
. On Linuxwith GCC this step is not needed.
qt的环境变量:
1,
export QTDIR=/home/yupont/qt453
export QTLIB=$QTDIR/lib
export QTINC=$QTDIR/include
export QMAKESPEC=$QTDIR/mkspecs/linux-g++
export MANPATH=$QTDIR/man:$MANPATH
export PATH=$QTDIR/bin:$PATH
不知道是不是都要设置
QTLIB和LD_LIBRARY_PATH有啥区别?
2,
export QTDIR=/home/d5000/qt453
export PATH=$QTDIR/bin:$PATH
export MANPATH=$QTDIR/man:$MANPATH
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
