我想编译main.f90，它依赖于单独文件中的三个子例程。对于第三个子例程，它也有三个 sub_subroutines。

  1. sub1.f
  2. sub2.f
  3. sub3_main.f sub3_sub1.f sub3_sub2.f sub3_sub3.f

运行以下代码将产生如下长错误消息。

gfortran main.f90 sub1.f sub2.f sub3_main.f sub3_sub1.f sub3_sub2.f sub3_sub3.f -o- test.exe

我搜索发现可能需要 flag -c，但我不确定编译顺序，以及如何将目标文件链接到独立程序中。或者它与这个问题有关：如何编译具有接口、模块和子例程的多文件夹 Fortran 项目。

提前致谢！

你应该能够做到：

gfortran -c sub1.f
gfortran -c sub2.f
gfortran -c sub3_main.f sub3_sub1.f sub3_sub2.f sub3_sub3.f
gfortran sub1.o sub2.o sub3_main.o sub3_sub1.o sub3_sub2.o sub3_sub3.o  main.f90 -o text.exe

或者

gfortran sub1.f sub2.f sub3_main.f sub3_sub1.f sub3_sub2.f sub3_sub3.f main.f90 -o text.exe

您应该只有一个程序和任意数量的程序（子程序和函数）。以上假设 sub3_main 是一个程序，并且您的程序在 main.f90 中。
