QT static compiler (MinGW compilation)

1. Why statically compile programs ？

By default , use QtCreator When compiling a program , Using dynamic compilation , This leads to the need to add corresponding Qt The library files , And a lot of dll file . If you want to package the generated program together with the required library into an executable program , And it can run on a computer without a development environment , Then you need to use static compilation .

2. Running environment

Windows10
QT Creator 4.11.0
QT 5.14.0 + Python 3.6 + gcc 7.3.0 + perl 5.22.1

3. Implementation steps

（1） install QT
QT5.14.0 Download address ：http://download.qt.io/archive/qt/5.14/5.14.0/
Select the version shown in the figure to download

install QT when , Remember to check “Sources”

（2） install Perl
Download address ：https://www.perl.org/get.html
Recommended download Strawberry Perl, Because compared with ActiveState Perl, It can be downloaded directly without registration
The installation directory ：D:\SoftwareInstall\StrawberryPerl\perl
Environment variables are added automatically during installation , If you don't add , Manually add ：

D:\SoftwareInstall\StrawberryPerl\perl\site\bin
D:\SoftwareInstall\StrawberryPerl\perl\bin

（3） install Python
Remember to check add during installation PATH environment variable
The installation directory ：D:\SoftwareInstall\Python3.6
Environment variables are added automatically during installation , If you don't add , Manually add ：

D:\SoftwareInstall\Python3.6\Scripts
D:\SoftwareInstall\Python3.6

（4） Installation environment inspection
open QT 5.14.0（MinGW 7.3.0 32-bit）

Enter the following command to check gcc Whether the compiler configuration is correct

gcc -v

Enter the following command to check perl Whether the interpreter configuration is correct

perl -v

Enter the following command to check python Whether the configuration is correct

python

Input exit() perhaps ctrl+z sign out python

（5） Configure static ratio compilation QT Information
stay D:\SoftwareInstall\Qt5.14.0\5.14.0 Create a new folder mingw73_32_static, For storing compiled files

Switch to QT Source directory D:\SoftwareInstall\Qt5.14.0\5.14.0\Src
Enter the following command ：

configure.bat  -static -release -confirm-license  -opensource -opengl desktop -platform win32-g++  -prefix "D:\SoftwareInstall\Qt5.14.0\5.14.0\mingw73_32_static" -sql-sqlite  -sql-odbc -qt-zlib -qt-pcre -qt-libpng -qt-libjpeg -qt-freetype -make libs  -nomake tools -nomake examples -nomake tests -skip qt3d  -skip qtcanvas3d -skip qtdatavis3d -skip qtlocation -skip qtwayland -skip qtwebchannel -skip qtwebengine -skip qtwebsockets -skip qtwebview

（6） Start compilation （ Longer time , about 3-4 Hours ）
In the （5） When step configuration is completed and no error message is output , You can start compiling , In the command line window just now, enter the following command to compile ：

mingw32-make

If the computer has good performance , You can use multithreading to compile ：

mingw32-make -j2

ps： What we use here is 2 Threads

（7） install
After compiling , Enter the following command in the command line window just now to install ：

mingw32-make install

After installation , You can do it in mingw73_32_static in , See the following ：

（8） Related configuration
modify D:\SoftwareInstall\Qt5.14.0\5.14.0\mingw73_32_static\mkspecs\common\g+±win32.conf
stay conf Add... To the file QMAKE_LFLAGS = -static
stay conf Modification in file QMAKE_LFLAGS_DLL = -static
