compiler-errors - 在模块中找不到 (1) 中引用的非法预处理器指令和符号

问题描述

我正在尝试用其他一些包编译 Quantum ESPRESSO 代码。在使用 Makefile 并稍微编译标志之后，我“获得”了如下错误。有没有办法解决这个问题？我是否缺少任何标志以避免错误？还是来自代码本身？

解决方案

错误消息和警告，例如

Warning: qevars.f90:30: Illegal preprocessor directive

通常由包含预处理器指令但不由预处理器预处理的 Fortran 代码处理。在 gfortran 中使用来启用预处理器或使用带有大写 F ( , )-cpp的文件扩展名。.F.F90

缺乏预处理可能会导致报告许多以下错误。
