回帖：fsu0413:QMAKE_LIBS_NETWORK 这一行用QQtPatcher改成了
QMAKE_LIBS_NETWORK = -lws2_32
你这个错误应该是QtGui模块的，可以看看相关的pri，如果执行了QQtPatcher的话也应该是该过的

重新安装 qt5.12.12，下载静态库解压，运行D:\ProgramFiles\Qt\Qt5.12.12-Windows-x86-MinGW7.3.0-staticFull>QQtPatcher.exe
提示信息是：
D:\ProgramFiles\Qt\Qt5.12.12-Windows-x86-MinGW7.3.0-staticFull>QQtPatcher.exe
Warning: Seems like you are using linked OpenSSL. Since we can't detect the path where you put OpenSSL in, you should probably manually modify D:/ProgramFiles/Qt/Qt5.12.12-Windows-x86-MinGW7.3.0-staticFull/mkspecs/modules/qt_lib_network_private.pri after you moved OpenSSL.
查看D:\ProgramFiles\Qt\Qt5.12.12-Windows-x86-MinGW7.3.0-staticFull\mkspecs\modules\qt_lib_gui_private.pri的内容如下：

查看D:\ProgramFiles\Qt\Qt5.12.12-Windows-x86-MinGW7.3.0-staticFull\mkspecs\modules\qt_lib_network_private.pri 的内容为：

我想 QQtPatcher.exe应该是修改成功了。
但是编译还是出现错误:
