Building Qt

1：先安装qt的依赖库

sudo apt-get install bison build-essential gperf flex ruby python libasound2-dev libbz2-dev libcap-dev \
libcups2-dev libdrm-dev libegl1-mesa-dev libgcrypt11-dev libnss3-dev libpci-dev libpulse-dev libudev-dev \
libxtst-dev gyp ninja-build libglu1-mesa-dev libfontconfig1-dev libx11-xcb-dev libicu-dev

不安装这些依赖库接下来运行configure的时候可能会报如下错误

WARNING: gperf is required to build QtWebEngine.

WARNING: bison is required to build QtWebEngine.

WARNING: flex is required to build QtWebEngine.

WARNING: host pkg-config not found

ERROR: The OpenGL functionality tests failed!
You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL[_ES2],
QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform.

 

如果发生类似这样的错 安装完相关依赖库之后 记得运行 rm config.cache来删除缓存的配置

 

2：下载qt源码

 git clone git://code.qt.io/qt/qt5.git

3：进入qt5目录

4：perl init-repository  初始化库和克隆子模块的变量

5：执行./configure -shared -opensource -nomake examples -nomake tests -confirm-license -prefix /usr/local/qt

6：make

7：make install
