用2个编译器编译fortran程序 [英] compile fortran program with 2 compilers

问题描述

我试图运行一个程序写在fortran其中子程序已编译gfortran和主程序已编译ifort：

这里的源代码：

子程序：

 子程序testsub 
 implicit none 
整数icarte 
读取（10，*）icarte 
写（*，*）icarte 
 return 
 end` 
  

主代码：

 程序测试
 implicit none 
 integer i 
 open（unit = 10，file =file_test）
 do i = 1,6 
 read（10，*）
 enddo 
 call testsub 
 close（10）
 end 
  

文件读取为：

  1 
 2 
 3 
 4 
 5 
 6 
 7 5 6 8 
 23 
  

像这样：

  gfortran -c testsub.f 
 
 ar rcs libtest.a testsub.o 
 
 ifort -o testexe test.f -L./ -ltest -L /.../ gcc / 4.7.1 / lib64 -lgfortran 
  

我获得：

 在文件testsub的第4行。 f（单位= 10，文件='fort.10'）
 Fortran运行时错误：文件结束
  

$ b b

看起来逻辑单元没有给出子程序。
我应该在某处添加编译选项...但我真的不知道什么和在哪里...
并回答问题如果我用同一个编译器编译这两个文件会发生什么？ 。 ：

解决方案

这不会工作。当您在主程序中打开文件时，ifort库的某处将打开该文件，并将与其关联的某些状态存储。 GFortran对ifort运行时库的内部状态一无所知，并试图在其自己的运行时库状态中查找单元，这显然失败了。

I am trying to run a program wrote in fortran where the subroutine has been compiled with gfortran and the main program has been compiled with ifort:

Here the source code:

subroutine:

subroutine testsub
    implicit none
    integer icarte
    read(10,*) icarte
    write(*,*)icarte 
    return 
    end`

main code:

program test
    implicit none
    integer i
    open (unit=10, file="file_test")
    do i=1,6
       read(10,*)
    enddo
    call testsub
    close(10)
    end

and the file read is:

1
2
3
4
5
6
7 5 6 8
23

And then I compile like that:

gfortran -c testsub.f

ar rcs libtest.a testsub.o

ifort -o testexe test.f -L./ -ltest -L/.../gcc/4.7.1/lib64 -lgfortran

and I obtained:

At line 4 of file testsub.f (unit = 10, file = 'fort.10')
Fortran runtime error: End of file

It looks like the logical unit was not given to the subroutine. I should add a compilation option somewhere... but I don't really know what and where... And to respond to the question "what happens if I compile both files with the same compiler ?" : the program runs perfectly :)

So if anyone as any idea...

解决方案

This won't work. When you open the file in the main program, somewhere in the bowels of the ifort library the file will be opened and some state associated with it stored. GFortran knows nothing about the internal state of the ifort runtime library, and tries to look up the unit in its own runtime library state, which obviously fails.
