Question

我创建了使用模块dimpar的签名文件。当我尝试使用签名文件进行编译时，f2py无法识别msects和maxpar，因此我得到：

/tmp/tmpj4zcO9/src.linux-i686-2.6/AtlasGeneratormodule.c:360: error: ‘msects’         undeclared here (not in a function)
/tmp/tmpj4zcO9/src.linux-i686-2.6/AtlasGeneratormodule.c:413: error: ‘maxpar’ undeclared here (not in a function)
/tmp/tmpj4zcO9/src.linux-i686-2.6/AtlasGeneratormodule.c:413: error: initializer element is not constant
/tmp/tmpj4zcO9/src.linux-i686-2.6/AtlasGeneratormodule.c:413: error: (near initialization for ‘f2py_parms_def[0].dims.d[0]’)
/tmp/tmpj4zcO9/src.linux-i686-2.6/AtlasGeneratormodule.c:360: error: ‘msects’ undeclared here (not in a function)
/tmp/tmpj4zcO9/src.linux-i686-2.6/AtlasGeneratormodule.c:413: error: ‘maxpar’ undeclared here (not in a function)
/tmp/tmpj4zcO9/src.linux-i686-2.6/AtlasGeneratormodule.c:413: error: initializer element is not constant

如何让f2py了解这些参数来自模块？

由于

签名文件：

!    -*- f90 -*-
! Note: the context of this file is case sensitive.

python module AtlasGenerator ! in 
interface  ! in :AtlasGenerator
    subroutine loadhistogramdata(wdo,xlat,xlon,ah,nhs,nhb,fs,bins) ! in :AtlasGenerator:AtlasGenerator.f90
        use dimpar  
          ... 
        real dimension((msects)) :: a
        real dimension((msects)) :: c
          ...    
        real dimension((maxpar)) :: param
          ...
    end subroutine loadhistogramdata
end interface 
end python module AtlasGenerator

模块dimpar ：

 module dimpar

  parameter (msects=36) 

  parameter (maxpar=80) 

 end module dimpar

以下是一些复制问题的示例代码：

dimpar.f90

module dimpar

      parameter (msects=36) 
end module dimpar

Array.f90

SUBROUTINE FIB(A,N)

use dimpar
REAL*8 A(msects)
DO I=1,N
 IF (I.EQ.1) THEN
    A(I) = 0.0D0
 ELSEIF (I.EQ.2) THEN
    A(I) = 1.0D0
 ELSE 
    A(I) = msects
 ENDIF
ENDDO
END

编译后我运行：

f2py -m useArray -h useArray.pyf array.f90

f2py --fcompiler=gfortran -c useArray.pyf array.o dimpar.o

发现问题，为了使其工作，我需要将模块放入签名文件中：

f2py -m useArray -h useArray.pyf dimpar.f90 array.f90

f2py使用模块 - 签名文件
