我试图为两个子例程使用相同的名称，但出现错误：

gfortran gshapes.f08 gshapes_utest.f08 -o gshapes_utest.x
gshapes_utest.f08:53.41:

call ellips%set_ellipse_corner (crnr1, crnr2)
                                     1
Error: Type mismatch in argument 'xlen' at (1); passed TYPE(gcorner) to REAL(4)

这是类型定义和相关的子例程：

type, public :: Ellipse
type(GCenter) :: centr  ! Center coordinate of ellipse
type(GCorner) :: crnr1  ! Upper left corner
type(GCorner) :: crnr2  ! Botton right corner
real :: xlen
real :: ylen            ! Size of ellipse in x- and y-directions
character (len=12) :: parm  ! Parameterisation of ellipse
contains
  procedure :: set_cpnt_ellipse
  procedure :: set_ellipse_corner => set_spnt_ellipse, set_tpnt_ellipse
  procedure :: print => print_ellipse
end type Ellipse

contains

! \brief Initialize geographical coordinate system grid object

subroutine set_cpnt_ellipse (ellips, gcentr, xlen, ylen)
  class(Ellipse) :: ellips
  type(GCenter) :: gcentr
  real :: xlen, ylen

  ellips%centr = gcentr
  ellips%xlen = xlen
  ellips%ylen = ylen
  ellips%parm = 'center'

end subroutine set_cpnt_ellipse


subroutine set_spnt_ellipse (ellips, gcrnr, xlen, ylen)
  class(Ellipse) :: ellips
  type(GCorner) :: gcrnr
  real :: xlen
  real :: ylen

  ellips%crnr1 = gcrnr
  ellips%xlen = xlen
  ellips%ylen = ylen
  ellips%parm = 'corner'

end subroutine set_spnt_ellipse


subroutine set_tpnt_ellipse (ellips, gcrnr1, gcrnr2)
  class(Ellipse) :: ellips
  type(GCorner) :: gcrnr1
  type(GCorner) :: gcrnr2

  ellips%crnr1 = gcrnr1
  ellips%crnr2 = gcrnr2
  ellips%parm = 'corners'

end subroutine set_tpnt_ellipse

我认为您可以将它们放在接口块中：

interface set_tpnt_ellipse
  module procedure set_spnt_ellipse, set_cpnt_ellipse
end interface
