QT安装
- 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
依赖库版本过高处理：
Depends: libcups2 (= 2.1.3-4) but 2.1.3-4ubuntu0.5 is to be installed
sudo aptitude 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
询问是否依然按当前高版本依赖库进行qt安装
Accept this solution? [Y/n/q/?] n
进行版本安装
Accept this solution? [Y/n/q/?] y
安装需要一定数量的内存，是否继续
Do you want to continue? [Y/n/?] y
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
- 下载qt源码
git clone git://code.qt.io/qt/qt5.git
-
进入qt5目录
-
perl init-repository 初始化库和克隆子模块的变量
-
执行./configure -shared -opensource -nomake examples -nomake tests -confirm-license -prefix /usr/local/qt
-prefix表示指定依赖文件的目录，需先检查/usr/local目录下是否有qt文件，如果没有则表示qt的依赖文件直接安装在/usr/local目录下，不需要指定 ./configure -shared -opensource -nomake examples -nomake tests -confirm-license -
make
-
make install
