Qt在命令行中使用“ mingw32-make”，并且.exe​​文件生成错误

Question

到目前为止，我已经在命令行中使用qmake -project和qmake来完成.pro文件Makefile.Debug和Makefile.Release的配置。但是，当我尝试在命令行中使用mingw32-make为项目生成.exe时，就会发生错误。

错误暗示该行：

64 ****missing separator ...Stop

但是在这种情况下，我已经为mingw32-make.exe和qmake.exe设置了所有环境变量。

有人说我应该在发生错误的位置（错误位置只有一个“ <<”）在makefile.release中添加一个Tab而不是空格，但是当我进行更改时会发生其他错误。而且我认为，由于Makefile都是由qmake命令自动生成的，所以也许这不是真正的问题... 这是错误信息以及Makefile.Release文件的一部分，以供参考 ：

这是Makefile。发布：

您正在使用Qt的MSVC版本。可以通过安装路径（D：\ qt5.10 \ 5.9.2 \ msvc2017_64）和输出“记住要调用vcvarsall.bat完成环境设置！”来推论得出。

从Qt的MSVC版本生成的QMake生成与MSVC兼容的makefile（至少默认情况下）。

安装Qt的MinGW版本，您就可以在项目中使用MinGW工具链。
