我正在尝试编译一些源代码，但是当我在终端中输入“make”命令时，它会产生错误。根据我有限的理解，当代码尝试从 .F 文件生成 .f90 文件时，似乎会出现问题。从网上的阅读看来，问题可能与 c 预处理器有关。看起来 ac 标头被添加到 .f90 文件中，而 gfortran 则出现了问题。 “make”命令的输出如下：

make: Circular mod_prec.o <- mod_prec.o dependency dropped.
make: Circular mod_prec.o <- mod_prec.o dependency dropped.

make: Circular mod_prec.o <- mod_prec.o dependency dropped.

我是 Linux 新手，对 C 或 FORTRAN 没有真正的了解，所以如果这个问题很愚蠢，我很抱歉。

输出文件（在本例中为 mod_prec.f90）包含以下标头，这是由于注释采用 C 格式而导致错误的原因：

答案1

这是海湾合作委员会错误#65387。正如您所看到的，它已被关闭，不是一个错误。 C/C++ 预处理器将 C/C++ 代码发送到后处理的 Fortran 程序中，因为它是一个C/C++预处理器。

如果您要将 C/C++ 预处理器与 Fortran 程序一起使用根据 GCC 自己的 Fortran doco，然后执行 GCC Fortran doco 没有告诉您的部分并使用-fstandalone。

答案2

问题出在 .F 源文件上。您尝试使用 C/C++ 样式注释，而 Fortran 编译器不会将它们视为注释。看起来它们的语法很糟糕。
