f2py erf函数lnk2019未解决的外部符号错误

问题描述 投票:1回答:1

我试图使用命令f2py:

C:\Python27\python.exe setup.py build_ext --inplace --fcompiler=g95

我的Fortran文件是:

module test_f90

implicit none

real *8 :: delta

contains

subroutine test_f(val, r)
    real*8, intent(out) :: val
    real*8, intent(in)  :: r
    val = 0.5*( 1 + erf(r/delta) )
end subroutine

end module test_f90

但我有这个错误:

test_fmod.o : error LNK2019: unresolved external symbol __g95_erf_r8 rÚfÚrencÚ d
ans la fonction _test_f90_MP_test_f
_test_f90.pyd : fatal error LNK1120: 1 externes non rÚsolus

如果我用val = 0.5*( 1 + erf(r/delta) )替换线val = 0.5*( 1 + sin(r/delta) ) f2py效果很好。所以问题是由于erf功能,但我不知道为什么。我认为sinerf是同一种功能?

python fortran f2py

如OP所报告的那样,使用gcc 4.1.2和g95 0.93来实现这一目标。
