我试图通过基于现有XML文件编写mexopts XML文件，在Windows 10上将MinGW gfortran与MATLAB R2019a结合使用。我已经在MinGW gcc中安装了cygwin，并且能够成功运行mex -setup并成功引用XML文件。当我尝试编译timestwo.F文件以测试设置（使用mex -R2018a timestwo.F90）时，出现了很多错误：

如果尝试使用随附的matlabroot\extern\examples\refbook\timestwo.F固定格式版本，输出将是相同的。

似乎未定义fintrf.h中定义的像mwPointer这样的mex特定类型，即使我已经包括了它的位置。为什么无法识别这些类型？
