Python f2py和capi_返回为空

我遇到了我认为可能是f2py中的一个bug，并回调到 python或者，也许我没有正确地使用东西。我创建了一个 非常简单的例子说明了我的问题：

要重现我的问题：

python 2.7.8

格弗特兰

f.f：

    subroutine test 
    cf2py intent(callback, hide) fred
    cf2py intent(callback, hide) bambam
    external fred
    external bambam
    integer n
    n = 4
    write (*,*) "Yabba Dabba Doo! In Subroutine TEST" 
    write (*,*) "Calling Fred:"
    call fred
    write (*,*) "Calling Bambam:"
    call bambam(n)
    end

      subroutine barney
      write (*,*) "In Subroutine BARNEY"
      write (*,*) "Calling Subroutine TEST"
      call test
      end

nocallback.f：

    subroutine test 
    cf2py intent(callback, hide) fred
    cf2py intent(callback, hide) bambam
    external fred
    external bambam
    integer n
    n = 4
    write (*,*) "Yabba Dabba Doo! In Subroutine TEST" 
    write (*,*) "Calling Fred:"
    call fred
    write (*,*) "Calling Bambam:"
    call bambam(n)
    end

      subroutine barney
      write (*,*) "In Subroutine BARNEY"
      write (*,*) "Calling Subroutine TEST"
      call test
      end

cb.py

f2py-c-m flintstone-flintstone.pyf callback.f nocallback.f

ipython>运行cb.py

我得到以下输出：

In [1]: run cb.py
 Yabba Dabba Doo! In Subroutine TEST
 Calling Fred:
fred!
 Calling Bambam:
bambam: I want 4 Brontosaurus Burgers!
 In Subroutine BARNEY
 Calling Subroutine TEST
 Yabba Dabba Doo! In Subroutine TEST
 Calling Fred:
fred!
 Calling Bambam:
capi_return is NULL
Call-back cb_bambam_in_test__user__routines failed.
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
/home/deen/Code/Python/sandbox/fluffy-kumquat/cb.py in <module>()
     12
     13 flintstone.test()
---> 14 flintstone.barney()
     15 
     16 

TypeError: bambam() takes exactly 1 argument (0 given)

然后，它将不会尝试分析bar，因为隐式假设所有没有引用foo参数的语句都与包装器函数生成无关。 例如，f2py需要一些帮助。请在.pyf文件中尝试以下签名：

 subroutine barney ! in :flintstone:nocallback.f
     use test__user__routines, fred=>fred, bambam=>bambam
     intent(callback, hide) fred
     external fred
     intent(callback,hide) bambam
     external bambam
 end subroutine barney

顺便说一句，而不是

f2py-c-m flintstone-flintstone.pyf callback.f nocallback.f

使用

f2py-c flintstone.pyf callback.f nocallback.f

因为模块名来自.pyf文件。

没有f2py，您是如何编译它的？你当时是怎么提供这些废话的？我真的不明白你在那个失败的案例中做了什么。我举的这个例子只是想让你了解一下我所看到的。。。如果您转到github存储库，您可以看到我使用的确切命令以及确切的错误消息…嗨，Vladimir-感谢您的建议。。。我应该包括所有的文件吗？或者这就足够了？如果你把你的修正作为一个答案，而不是将其编辑到问题中，可能会更清楚一点（请参见）请不要在标题中使用修正。此外，最好张贴答案，不要将答案编辑到问题中。
