编译错误:无法打开模块文件 [英] Error in compiling: Can't open module file

问题描述

我有此代码:

        PROGRAM xfit
!   driver for routine fit
    USE nrtype; USE nrutil
    USE nr
    USE ran_state, ONLY : ran_seed
    IMPLICIT NONE
    INTEGER(I4B), PARAMETER :: NPT=100
    REAL(SP), PARAMETER :: SPREAD=0.5_sp
    INTEGER(I4B) :: mwt
    REAL(SP) :: a,b,chi2,q,siga,sigb
    REAL(SP), DIMENSION(NPT) :: harvest,sig,x,y
    call ran_seed(sequence=731)
    x(:)=arth(0.1_sp,0.1_sp,NPT)
    call gasdev(harvest)
    y(:)=-2.0_sp*x(:)+1.0_sp+SPREAD*harvest
    sig(:)=SPREAD
    do mwt=0,1
        if (mwt == 0) then
            write(*,'(//1x,a)') 'Ignoring standard deviation'
            call fit(x,y,a,b,siga,sigb,chi2,q)
        else
            write(*,'(//1x,a)') 'Including standard deviation'
            call fit(x,y,a,b,siga,sigb,chi2,q,sig)
        end if
        write(*,'(1x,t5,a,f9.6,t24,a,f9.6)') 'A = ',a,'Uncertainty: ',&
            siga
        write(*,'(1x,t5,a,f9.6,t24,a,f9.6)') 'B = ',b,'Uncertainty: ',&
            sigb
        write(*,'(1x,t5,a,4x,f10.6)') 'Chi-squared: ',chi2
        write(*,'(1x,t5,a,f10.6)') 'Goodness-of-fit: ',q
    end do
    END PROGRAM xfit

但是当我编译它时，出现以下错误

But when I compile it I get the following error

USE ran_state, ONLY : ran_seed
     1
Fatal Error: Can't open module file 'ran_state.mod' for reading at (1):
              No such file or directory

您能告诉我我该怎么解决吗?

Could you please tell me how I can solve it?

推荐答案

像这样构建时，我看到了相同的错误:

I've seen the same error when I built like this:

gfortran test.f90 -o test.exe 

使用模块名

use modulename

1

致命错误:无法打开模块文件'modulename.mod'以便在以下位置读取 (1):没有这样的文件或目录

Fatal Error: Can't open module file 'modulename.mod' for reading at (1): No such file or directory

假设modulename.mod位于/usr/local/include中，并且在/usr/local/lib中具有某些依赖性.

Let's say modulename.mod is in /usr/local/include with some dependencies in /usr/local/lib.

您可以通过以下操作使错误消失:

gfortran test.f90 -o test.exe -I/usr/local/include -L/usr/local/lib
