Qt4.8.5 x86开发环境搭建【完整流程】

环境：workstations VM11、Ubuntu

Qt4.8.5 开发环境搭建【完整流程】关于编译出现的问题，我另开一贴再次解决。

1.首先在 ubuntu10.04 系统的/home/ye 目录中，创建一个 Qt 文件夹，复制文件qt-everywhere-opensource-src-4.8.5.tar.gz 到 Qt 文件夹中，并且解压：

$ tar –zxvf qt-everywhere-opensource-src-4.8.5.tar.gz

2. 编译 qt 需要 g++，在终端输入 g++ -v，如果出现如下图所示，说明已经安装了 g++，否则执行命令来
安装 g++：

$ sudo apt-get install g++

    安装成功：

yechuang@yechuang:~/Qt$ g++ -v
Using built-in specs.
Target: i486-linux-gnu
Configured with: ../src/configure -v --with-pkgversion='Ubuntu 4.4.3-4ubuntu5.1' --with-bugurl=file:///usr/share/doc/gcc-4.4/README.Bugs --enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr --enable-shared --enable-multiarch --enable-linker-build-id --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --with-gxx-include-dir=/usr/include/c++/4.4 --program-suffix=-4.4 --enable-nls --enable-clocale=gnu --enable-libstdcxx-debug --enable-plugin --enable-objc-gc --enable-targets=all --disable-werror --with-arch-32=i486 --with-tune=generic --enable-checking=release --build=i486-linux-gnu --host=i486-linux-gnu --target=i486-linux-gnu
Thread model: posix
gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5.1) 
yechuang@yechuang:~/Qt$ 

    再安装所需的三个包：
yechuang@yechuang:~/Qt$ sudo apt-get install libX11-dev libXext-dev libXtst-dev

$ sudo apt-get install libX11-dev libXext-dev libXtst-dev

…………现象

正在设置 x11proto-xext-dev (7.1.1-2) ...
正在设置 libxext-dev (2:1.1.1-2ubuntu0.1) ...
正在设置 libxi6 (2:1.3-3ubuntu0.2) ...

正在设置 libxtst-dev (2:1.1.0-2ubuntu0.1) ...

ldconfig deferred processing now taking place

安装成功 。

3. 进入刚刚解压的 qt 源码目录中：cd qt-everywhere-opensource-src-4.8.5/; 执行./configure, 出现如下图所
示，选择开源版本

yechuang@yechuang:~/Qt/qt-everywhere-opensource-src-4.8.5$ ./configure
Which edition of Qt do you want to use ?

Type 'c' if you want to use the Commercial Edition.
Type 'o' if you want to use the Open Source Edition.

o


This is the  Open Source Edition.

the Lesser GNU General Public License (LGPL) versions 2.1.
You are also licensed to use this software under the terms of
the GNU General Public License (GPL) versions 3.

Type '3' to view the GNU General Public License version 3.
Type 'L' to view the Lesser GNU General Public License version 2.1.
Type 'yes' to accept this license offer.
Type 'no' to decline this license offer.

Do you accept the terms of either license? yes
……………………

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into /usr/local/Trolltech/Qt-4.8.5

To reconfigure, run 'make confclean' and 'configure'.

4.编译源码，执行make

如果安装成功，则生成makefile ,如果没有正常生成请看 另一帖：Qt4.8.5 开发环境搭建【编译出现的问题】

yechuang@yechuang:~/Qt/qt-everywhere-opensource-src-4.8.5$ ls
bin              configure.exe  INSTALL             Makefile      src
changes-4.8.5    demos          LGPL_EXCEPTION.txt  mkspecs       templates
config.profiles  doc            lib                 plugins       tools
config.status    examples       LICENSE.FDL         projects.pro  translations
config.tests     imports        LICENSE.GPL3        qmake         util
configure        include        LICENSE.LGPL        README

在这里就看出了已经生成了makefile了，执行

yechuang@yechuang:~/Qt/qt-everywhere-opensource-src-4.8.5$ make

这个过程时间有点长，耐心等待。

5.完成编译后安装

yechuang@yechuang:~/Qt/qt-everywhere-opensource-src-4.8.5$ sudo make install

6.完成安装后查看系统中的/usr/local/Trolltech 里面安装了编译的 Qt4.8.5

yechuang@yechuang:~/Qt/qt-everywhere-opensource-src-4.8.5$ ls /usr/local/Trolltech/
Qt-4.8.5

7.配置环境变量, $ sudo vim /etc/profile, 将/usr/local/Trolltech/Qt-4.8.5/bin 加入环境变量,然后 生效环境
变量$ source /etc/profile;

yechuang@yechuang:~/Qt/qt-everywhere-opensource-src-4.8.5$ sudo vi /etc/profile

# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).

if [ -d /etc/profile.d ]; then
  for i in /etc/profile.d/*.sh; do
    if [ -r $i ]; then
      . $i
    fi
  done
  unset i
fi
export PATH=/usr/local/Trolltech/Qt-4.8.5/bin:$PATH
if [ "$PS1" ]; then
  if [ "$BASH" ]; then
    PS1='u@h:w$ '
    if [ -f /etc/bash.bashrc ]; then
        . /etc/bash.bashrc
    fi
  else
    if [ "`id -u`" -eq 0 ]; then
      PS1='# '
    else
      PS1='$ '
    fi
  fi
fi

问题1：出现无法更改环境变量情况，在http://www.cnblogs.com/yechuang/p/4511348.html中查看解决办法。

8. Qt4.8.5 编译、安装和配置完成

$ sudo qmake –v

QMake version 2.01aUsing Qt version 4.8.5 in /usr/local/Trolltech/Qt-4.8.5 /lib
 

问题2：

qmake: could not exec '/usr/lib/i386-linux-gnu/qt4/bin/qmake': No such file or directory
