Topic: Problem with modules

Hi Jeff,
I have another one for you.

In trying to build my project, notice that A_Struct_Mod.f90 compiles without errors


Compiling .\Source\A_PSInfo_Mod.f90
Compiling .\Source\A_Struct_Mod.f90
Compiling .\Source\AllBlank.f90
.
.
.

However, when it trys to compile ElevGet.f90, I get the error listed below:

.
.
.
Compiling .\Source\DNorm.f90
Compiling .\Source\ElevGet.f90
.\Source\ElevGet.f90:68.29:

     Vol = Interp(Etry, Expd%Elev, Expd%Volume, Expd%nStrPts)
                             1
Error: Symbol 'expd' at (1) has no IMPLICIT type
Error(E42): Last command making (.\Build\ElevGet.o) returned a bad status
Error(E02): Make execution terminated

* Failed *


This is the module that contains the "Type(Expanded) :: Expd" statement:
    !
!
Module A_Struct_Mod
!
! Module to establish allocatable arrays and their associated variables.
!
! Used with the Vegetative Overtopping Protection program.

Logical(1)                :: Breached      ! Switch to indicate stress greater than 100%

!
End Module A_Struct_Mod


I have tried everything I can think of to get around this problem, but no luck. It has worked in the past, but after I changed Exp (which was the Type (Expanded) name originally) to avoid confusion with the EXP function, I started getting this error.  It's almost like it isn't deleting the old compiled module.

This happen with 2.19 and 2.20 builds.  Any suggestions?

Re: Problem with modules

Don,

Could you also post a portion of the routine or file that uses this module (ElevGet.f90)?  Also, I'm assuming you've tried it already, but performing a Clean first doesn't fix the problem?

Yes, I tried cleaning and no, it didn't help.

Re: Problem with modules

Hi Jeff - I think I have discovered the problem with modules.  My project is set up as follows:

C:\Projects\WinDAM B  which contains the .prj, .exe and test dataset.  There are three sub-folders - Build, Modules and Source.  The Build and Modules folders are the used by Simply Fortran.  Source contains all my source programs - modules, subroutines and main.  I discovered that in the source folder, for each module, there was a corresponding .mod file that were not being removed by "Clean".  I deleted them and the program compiled and ran to conclusion.  I checked after my last compile and source does not contain any .mod files.  I think we can probably chalk this one up to operator error....
