编译环境

1. CentOS 64位 Desktop 版本：6.5

编译前的准备：

CentOS的用户默认没有root权限，如果当前用户没有权限root，则可以在终端里面执行下面的命令：

su root
sudo sed -i '/root\tALL=(ALL)/a *自己的用户名*\tALL=(ALL)\tALL' /etc/sudoers
exit

需要替换自己的用户名

安装git

sudo yum install git

安装开发工具

sudo yum groupinstall "Development Tools"

安装开发库

sudo yum install libX11-devel, libXext-devel, libXtst-devel
sudo yum install libX11-devel libXext-devel libXtst-devel
sudo yum install libXrender-devel
sudo yum install zlib-devel
sudo yum install openssl-devel
sudo yum install flex bison gperf libicu-devel libxslt-devel ruby
sudo yum install libxcb libxcb-devel xcb-util xcb-util-devel
sudo yum install freetype-devel
sudo yum install fontconfig-devel

下载安装qt 4.8.6

wget http://download.qt-project.org/official_releases/qt/4.8/4.8.6/qt-everywhere-opensource-src-4.8.6.tar.gz
tar xvfz qt-everywhere-opensource-src-4.8.6.tar.gz
cd qt-everywhere-opensource-src-4.8.6
./configure -webkit
gmake
sudo gmake install

注意 在执行 ./configure -webkit 命令的时候，需要确保webkit， ssl，fontconfig，XRender能够被正确编译，如下： Qt 3 compatibility ..... yes

编译安装cmake

因为CentOS自带的cmake（或者通过rpm安装的cmake）版本比较低，因此需要自己编译安装。 wget http://www.cmake.org/files/v2.8/cmake-2.8.12.2.tar.gz
tar -zxv -f cmake-2.8.12.2.tar.gz
cd cmake-2.8.12.2
./configure
gmake
sudo make install

下载编译WizNote

git clone https://github.com/WizTeam/WizQTClient.git
cd WizQTClient
git checkout testing
./centos-package.sh

如果没有错误，则会在WizQTClient同级目录下面，生成一个WizNote文件夹，进入后可以执行bin/wiznote来运行WizNote。

安装QtCreator

注意：如果您不需要开发，则不需要安装QtCreator即可。如果需要开发调试，可以安装。

因为CentOS上面的libstdc++.so.6 版本太低，因此还需要编译安装gcc才可以正确运行QtCreator。

首先，从qt-project.org 下载QtCreator并且安装。安装后运行QtCreator，通常会提示有些插件无法加载，从而导致无法正常打开工程。我们需要编译gcc。

编译安装gcc

配置过程中需要联网安装需要的依赖。

wget http://ftp.tsukuba.wide.ad.jp/software/gcc/releases/gcc-4.8.1/gcc-4.8.1.tar.bz2
tar -jxvf gcc-4.8.1.tar.bz2
cd gcc-4.8.1
./contrib/download_prerequisites
cd ..
mkdir gcc-build-4.8.1
cd gcc-build-4.8.1
../gcc-4.8.1/configure --enable-checking=release --enable-languages=c,c++ --disable-multilib
make -j4
sudo make install

到这里可以编译并安装最新版本的gcc。但是因为系统里面的libstdc++.so.6在 /usr/lib64 里面，而我们安装的在 /usr/local/lib64里面，因此需要更新一下链接。

sudo rm /usr/lib64/libstdc++.so.6
sudo ln -s /usr/local/lib64/libstdc++.so.6.0.18 /usr/lib64/libstdc++.so.6

然后重新打开QtCreator，就可以正常运行了。

最后，我们自己编译的qt library在/usr/local/Trolltech/Qt-4.8.5 里面，需要在QtCreator选项里面指定。

如果使用QtCreator打开WizNote工程并编译，请参考文章：在Ubuntu下面编译WizNote Qt Project
