Fortran 编译器突然找不到“deallocate”

Question

我正在开发 Fortran 代码，一天中的大部分时间编译、链接和执行都没有问题。突然，当我尝试编译时，在链接阶段编译器告诉我它找不到“deallocate_”。具体来说，

undefined reference to `deallocate_'

这怎么可能？顺便说一句，它发现“分配”没有问题。知道出了什么问题吗？我在 Red Hat 机器上使用 Intel 19.0，

mpiifort

。

Answer 1

像往常一样，没有代码，一切都是猜测，但这是一种方法：

Program dealloc

  Implicit None

  Call deallocate

End Program dealloc
