我想将makefile的编译器从pgi更改为gfortran，我想知道如何更改FC和FFLAGS才能使其工作

Question

我有5个makefile，它们是为pgi编译器设计的。然而，我的系统正在使用gfortran，我不知道如何使它们与我的系统一起工作，也不知道我应该如何更改FC和FFLAGS。我是Linux操作系统的新手，我使用的是Ubuntu 20.04。以下是文件包含的内容：

SHELL=/bin/sh

查看I/O API M3ToolsMakefile模板。

请注意ioapi/Makeinclude$｛BIN｝各种类型的文件——在这种情况下，$BIN=Linux2_x86_64gfort(适用于gfortran版本10之前的版本(或$BIN=Linux2_x86_64gfort10(适用于gfort ran10或更高版本(将为您提供所需的标志。

还要注意，这个m3tools/Makefile.template与底层Models-3 I/O API的集成比代码作者提供的更好。。。。
