ubuntu - 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 以使其工作

Question

我有 5 个为 pgi 编译器设计的 makefile。但是，我的系统正在使用 gfortran，我不知道如何让它们与我的系统一起使用，以及我应该如何更改 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
FC= pgf90
FFLAGS= -O -Mvect=sse -Mextend -Msecond_underscore -Mlfs -Bstatic

          -I/models/CMAQ/lib/netcdf-3.6.0-p1.mulcahy/include \
          -I$(CURDIR)/INCLDIR

OBJS = \
     checkmem.o \

Answer 1

看看the I/O API M3Tools Makefile template .
请注意，各种类型的 ioapi/Makeinclude.${BIN} 文件——在本例中为 $BIN=Linux2_x86_64gfort for gfortran before version 10, or $BIN=Linux2_x86_64gfort10 for gfortran versions 10 or later会给你你需要的标志。
还要注意，这个 m3tools/Makefile.template 与底层 Models-3 I/O API 的集成比代码作者给你的要好得多。
