Trying to implement code example for derived type IO with no success

[awa5114]

I'm trying to learn more about derived type IO. To start off with I am using examples from this page: https://software.intel.com/en-us/node/678729

I have created a Visual Studio solution and copied the contents of example1 into a source file. When I run the solution I get errors:

Error	9	Compilation Aborted (code 1)	D:\TEMP\FortranTest\Console1\Console1\Source1.f90	1	
Error	7	 error #7002: Error in opening the compiled module file.  Check INCLUDE paths.   [TYPES]	D:\TEMP\FortranTest\Console1\Console1\Source1.f90	51	
Error	4	 error #6546: A required END statement for the interface-body is missing.	D:\TEMP\FortranTest\Console1\Console1\Source1.f90	14	
Error	8	 error #6457: This derived type name has not been declared.   	D:\TEMP\FortranTest\Console1\Console1\Source1.f90	52	
Error	5	 error #6268: The keyword ASSIGNMENT or OPERATOR was expected in this context   [WRITE]	D:\TEMP\FortranTest\Console1\Console1\Source1.f90	12	
Error	6	 error #6268: The keyword ASSIGNMENT or OPERATOR was expected in this context   [READ]	D:\TEMP\FortranTest\Console1\Console1\Source1.f90	8	
Error	3	 error #5082: Syntax error, found IDENTIFIER 'UDIO_WRITE_ARRAY' when expecting one of: <END-OF-STATEMENT> ;	D:\TEMP\FortranTest\Console1\Console1\Source1.f90	13	
Error	1	 error #5082: Syntax error, found IDENTIFIER 'FORMATTED' when expecting one of: * .NOT. . + - /) ** / // .LT. < .LE. <= .EQ. == .NE. /= .GT. > ...	D:\TEMP\FortranTest\Console1\Console1\Source1.f90	8	
Error	2	 error #5082: Syntax error, found IDENTIFIER 'FORMATTED' when expecting one of: * .NOT. . + - /) ** / // .LT. < .LE. <= .EQ. == .NE. /= .GT. > ...	D:\TEMP\FortranTest\Console1\Console1\Source1.f90	12	

I know I'm allowed to have modules in the same file as the main executing program because the below code:

module mymod
    contains
        subroutine hello
            print *, "hello"
        end subroutine hello
    end module mymod
    
program test
    use mymod    
    call hello
    
    end program test

compiles, runs and outputs correct output.

Why are none of the examples from the provided link working? I feel like they should since they come from the main intel website and I am using intel products.

Just now, I tried all three examples using Ifort 17.0.4, and all worked fine. Example-1 does not use module UDIO; therefore, you have mixed up the examples in some way. What does your Source1.f90 contain, and which version of the compiler did you use?

[awa5114]

Yes, sorry. I just edited the original question with the errors from example 1. Note the include module problem still occurs Error 7 (error code #7002).

Also you might recall from my previous question (https://software.intel.com/en-us/forums/intel-visual-fortran-compiler-for-windows/topic/737278) that I cannot  use ifort. I have several problems with compiling using the VS/Intel Fortran command line which I strongly believe are linked to my lack of administrative privileges (company policy) on my windows machine. The main culprit is ifort: error #10037: could not find 'link'. I would like to refer you to some previous discussions I started about this ...

https://stackoverflow.com/questions/33065962/ifort-error-10037-could-not-find-link/36248786#36248786

I have not found as yet a resolution to this problem, since any proposed solution should assume I have NO administrative rights in my system, and I don't see that changing in the near future.

Now, back to my original question, I am compiling Example 1 using a full Visual Studio solution (not the command line). This is where I am copying the errors from.... Do you suspect that might be a cause?

[andrew_4619]

it looks like simple source errors in your post, Attach the source file, that would be much better than guessing what the problem is.

[awa5114]

I'm not sure how the source file would help. All I am doing is creating a one-file console application project and pasting the code from the webpage then pressing Run. But here it is for reference...

[mecej4]

I think that you should concentrate on repairing your Ifort+VS installation to the point that you can compile, link and run simple Fortran programs. After that is done you can explore advanced features of the language.

[awa5114]

@mecej4 I think so too. One hundred percent. Except I can't. In order to get ifort to work I would have to get administrative privileges which is against company policy. Of course, it is entirely their fault that their installation of VS 2012 contains this (rather major) glitch with respect to ifort not working. However theres really nothing I can do except use the current resources  I have available...

[Steve_Lionel]

I don't think the install is the problem.

One issue I have seen is that if you just copy and paste from the Intel documentation, it sometimes loses line wraps.

As for the source1.f90 you attached, it compiles fine for me. The error messages you showed in the original post suggest that you compiled something different. Please do the following from a Fortran command prompt:

type source1.f90
ifort -c source1.f90

and show the output.

[mecej4]

Usually, when an employer restricts access to end users on company PCs, they have to provide one or more system administrators who are responsible for installing and servicing software (such as Parallel Studio) that their end users are required to use in order to perform their job.

I suspect that there is some inconsistency as to version numbers, because the VC startup batch file reported (in your thread https://software.intel.com/en-us/forums/intel-visual-fortran-compiler-for-windows/topic/720567#comment-1900033 ) that it could not find VS110COMNTOOLS. The "110" in the name is the version number of Visual Studio. If the installed version is a different version, the combination may or may not work. Fixing these issues is, again, the administrators' responsibility.

[Steve_Lionel]

110 is correct for VS2012.

Oh - you're using a five-year-old compiler! UDIO was not supported until the 14.0 compiler.

[awa5114]

So User Defined Derived Type IO is not supported in the version I have at all? If so how come the error log is explicitly referring it when I try to do a namelist? I have tried this in my code for a large derived type named CalParams

 subroutine GetNameList
        
        open(682, file = "namelist.txt")
        namelist /mynamelist/ CalParams
        write(682, nml = mynamelist)
    end subroutine GetNameList

When I call this routine from my main program I get this error

Error 2 Compilation Aborted (code 1) D:\geo-install\dynamic\trunk_modified\VS\MyMod.f90 1 
Error 1  error #5415: Feature not yet implemented: Allocatable or pointer fields require user-defined derived-type I/O procedure. D:\geo-install\dynamic\trunk_modified\VS\MyMod.f90 87 
 

[Steve_Lionel]

No, it is not supported at all in the version you have. Yes, a "not yet implemented" message was added - the previous behavior was an internal compiler error.

[awa5114]

Hi all. 

I am back at this again. Thanks to some excellent advice I received back in this thread https://software.intel.com/en-us/forums/intel-visual-fortran-compiler-for-windows/topic/720567 I am proud to say I can now compile simple programs from the command line.

So my understanding is that version 13 does not support derived type IO. Just for reference, this is why I sought to use this functionality in the first place https://software.intel.com/en-us/forums/intel-visual-fortran-compiler-for-windows/topic/737278

I need to make different runs of the software I am using and compare how the derived types in my program change for different configurations and inputs. I am particularly interested in listing exactly those variable names from these derived types for which the value has changed. What viable alternative can I use? some unsuccessful attempts so far have involved:

• list directed IO
• derived type IO
• compiling with debug symbols requested

I am also currently looking into Profile Guided Optimization (PGO). Looks promising but might be an overkill... Any ideas? Thanks very much.

[Steve_Lionel]

You could use Namelist I/O, writing the before and after into character arrays, and then comparing the elements to see what has changed, including names.
