[SOLVED] I get "'found module version 0, expected 9" Error while running a fortran 90 program.

Hi everybody.

I am trying to run a Fortran 90 code by issuing the following command:

hassan@ubuntu:~/popratio$ g95 main3.f90

But I got the following error

Fatal Error: While reading module 'precision' found module version 0, expected 9.

My "precision" module contains the following lines:

!-----------------------------------------------------------------------
!* This module defines single/double precision parameters and
!* sets the accuracy of the floating point operations.
!-----------------------------------------------------------------------
module Precision
implicit none
public
integer, parameter :: SP = kind (1.0) ! single precision definition
integer, parameter :: DP = kind (1.0D0) ! double precision definition
! the following corresponds to the old Fortran 77's double precision data type:
integer, parameter :: WP = DP ! working precision definition
end module Precision
----------------------------------------------------

I would be grateful if any one could help me in this matter.

With best regards,
Hassan

It seems to work for me with gfortran. How are you using the module in your main code?

Code:

$ cat precision.f90
module Precision
implicit none
public
integer, parameter :: SP = kind (1.0)
integer, parameter :: DP = kind (1.0D0)
integer, parameter :: WP = DP
end module Precision


use Precision

print *,SP,DP,WP
end
$ gfortran precision.f90 
$ ./a.out 
           4           8           8

Thanks for the reply.

I uploaded the whole code to the following ftp server:

ftp://ftp.ing.iac.es/hassan/

I need to run the file "main1.f90" through "main5.f90".
But when I try to run them using following command I got
the above error:

hassan@ubuntu:~/popratio$ g95 main3.f90

Also when I type :

hassan@ubuntu:~/popratio$ gfortran Precision.f90

I got the following error:

/usr/lib/crt1.o: In function `_start':
(.text+0x18): undefined reference to `main'
collect2: ld returned 1 exit status
hassan@ubuntu:~/popratio$

Thanks.
hassan

You can't compile main without also compiling its dependencies. You can't compile Precision.f90 into an executable because there is no main function to actually execute (it just contains a library of functions). You could compile Precision.f90 itself by adding the -c flag to your compiler, but it wouldn't do much good. Basically, you need to compile all of the dependencies in order to compile the main routine. After some playing around, I found the full set in the right sequence:

Code:

gfortran d*.f la_precision.f90 Precision.f90 f77_lapack.f90 la_erinfo.f90 sgemv.f slamc1.f slamc3.f slamc4.f slamc5.f slabad.f sger.f sgetrs.f sgerfs.f slamc2.f sasum.f scopy.f strsv.f saxpy.f sdot.f isamax.f sswap.f sscal.f sgemm.f slacon.f slatrs.f srscl.f ieeeck.f sgetf2.f slaswp.f strsm.f slassq.f ilaenv.f sgetrf.f slantr.f slange.f sgecon.f lsame.f xerbla.f idamax.f sgesvx.f slamch.f sgeequ.f slaqge.f slacpy.f la_auxmod.f90 la_dgesvx*.f90 PhysMath.f90 spline.f90 FieldInt.f90 f90_lapack.f90 PopRatio.f90 main3.f90 -o main3

I'm not sure who wrote the makefile, but it has a few errors, and won't run on my system.

Hi suicidaleggroll,

I would like to thank you very much for your help.
At last it worked! This code was very important for my thesis
and I really appreciate your help.

With best regards,
Hassan
