QT源码编译

编译环境配置

1，下载Qt源码，这里使用QT5.12.8的源码官网： Index of /

国内镜像网站

这里给大家推荐几个国内著名的 Qt 镜像网站，主要是各个高校的：

• 中国科学技术大学：Index of /qtproject/
• 清华大学：Index of /qt/ | 清华大学开源软件镜像站 | Tsinghua Open Source Mirror
• 北京理工大学：http://mirror.bit.edu.cn/qtproject/
• 中国互联网络信息中心：Index of /qt/ | 清华大学开源软件镜像站 | Tsinghua Open Source Mirror

2，安装VS2017

3，安装python 2.7 Download Python | Python.org

4，安装ActivePerl  Download & Install Perl - ActiveState

5,  安装 Ruby+Devkit Downloads

在开始菜单里进入Visual Studio 2017文件夹，打开“VS2017 x86本机工具人员命令提示符”，进入cmd窗口模式：
1.cd 下载的Qt源码目录；
2.执行

WARNING: QDoc will not be compiled, probably because libclang could not be located. This means that you cannot build the Qt documentation.

Either ensure that llvm-config is in your PATH environment variable, or set LLVM_INSTALL_DIR to the location of your llvm installation.
On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution.
On macOS, you can use Homebrew's llvm package.
On Windows, you must set LLVM_INSTALL_DIR to the installation path.

WARNING: Python version 2 (2.7.5 or later) is required to build QtWebEngine.

Qt is now configured for building. Just run 'nmake'.
Once everything is built, you must run 'nmake install'.
Qt will be installed into 'F:\firefoxDownload\qt-everywhere-src-5.12.8\build'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

编译
F:\firefoxDownload\qt-everywhere-src-5.12.8>nmake

这个过程 比较慢长：

编译完成后生成的dll在各模块的bin目录下

 

如果只改动很小，可以单独模块编译
例如编译qtbase模块
F:\firefoxDownload\qt-everywhere-src-5.12.8>cd qtbase
F:\firefoxDownload\qt-everywhere-src-5.12.8\qtbase> nmake

上面可以看到qtbase模块里由很多子模块构成，我们也可以编译单独的子模块，例如编译qtbase模块里的widgets模块
F:\firefoxDownload\qt-everywhere-src-5.12.8\qtbase>cd src
F:\firefoxDownload\qt-everywhere-src-5.12.8\qtbase\src>cd widgets
F:\firefoxDownload\qt-everywhere-src-5.12.8\qtbase\src\widgets>nmake

这个时候编译的就是widgets模块
