Runtime error 47 after conversion from CVF to IntelVF

irpug — Fri, 29 Feb 2008 16:48:03 GMT

I have been trying to nail down a problem with some legacy code that was originally compiled on Compaq Visual Fortran. I have tried many compiler options and code modifications, but it seems to be a .DLL issue. The source code is all *.F files and I am using Intel Visual Fortran and MS Visual Studio .NET 2005. The code compiles fine with no warnings or errors, but when I run the file it breaks on the following line:

write (4000+inum1,2000) iyr, iida, ii-1, (varii(j), j = 1, 22)

The open statement that is run previous to the write is:

open (4000+inum1s(idum), file='autocal1.out', ACTION='READWRITE')

note: inum1 = 1, and inum1s(idum) = 1

The run-time errorI keep getting when executing from the console isas follows:

forrtl: severe (47): write to READONLY file, unit 1112, file C:SWAT TestREVSIE

The error I am getting when executing within the Visual Studio IDE is:

'myfile.exe': Loaded 'C:SWAT TestDevelopmentMy2005Myfile2005Debugmyfile.exe', Symbols loaded.

'myfile.exe': Loaded 'C:WINNTsystem32 tdll.dll', No symbols loaded.

'myfile.exe': Loaded 'C:WINNTsystem32imagehlp.dll', No symbols loaded.

'myfile.exe': Loaded 'C:WINNTsystem32msvcrt.dll', No symbols loaded.

'myfile.exe has triggered a breakpoint

I have checked the file that isattempted to bewritten to and it is not a readonly file. When I change: write (4000+inum1,2000) iyr, iida, ii-1, (varii(j), j = 1, 22) to: write (8001,2000) iyr, iida, ii-1, (varii(j), j = 1, 22), the file fort.8001 is written with the correct data. This leads me to believe it has something to do with the open statement, or some missing DLL's.

We want to move to the Intel compilerifwe can get this to work, soany suggestions would be appreciated.

What exact version of the compiler are you using? How many of these files does the program open?

One thing to try - in the project properties, select Fortran > Data. Change the "Local variable storage" to "All variables SAVE" and rebuild.

Compiler version: 10.1

The downloaded and installed compiler is: w_fc_p_10.1.011_novsppe.exe

I have tried your suggestion but had the same result. In this instance the program is writing to 6 files, but it iterates through close and open statements (sample below):

close(4000+inum1s(idum))

if (inum1s(idum) <= 70 .and. inum1s(idum) > 0) then

open (9000+inum1s(idum),file=auto_in,recl=350)

select case (inum1s(idum))

case(1)

open (4000+inum1s(idum), file='autocal1.out', &

& ACTION='READWRITE')

case(2)

open (4000+inum1s(idum), file='autocal2.out', &

& ACTION='READWRITE')

... etc

The compiler is set to optimize for maximum speed, triedIntel Pentium and Pentium 4, tried I/O Buferring Yes and No.

Please try 10.1.019 and see what happens. If the problem is still there, please submit a test case to Intel Premier Support and we'll be glad to look at it.

Well, I downloaded and installed 10.1.019 (which is reported as: Intel Fortran Compiler Integration for Microsoft Visual Studio 2005, 10.1.4156.2005, Copyright (C) 2002-2008 Intel Corporation), recompiled all the modules, but the same results.

I am wondering why I am getting the no symbols loaded for the 4 dll's (ntdll, kernel32,...)? I checked the C:WINNTsystem32 subdir and they are in there.

Will experiment some more. Thanks for your quick responses. If there is something else you think I should try, let me know.

Help > About in Visual Studio shows you the VS integration version, not the compiler version.

The messages about no symbols loaded can be ignored. It's saying that there's no debug information for those system DLLs and that's of interest only if you want to debug those DLLs.

I note that the error message names fort.1112 as the file name. This tells me that at the time the WRITE is done, that unit is not open, or maybe something else is at work. I note that the WRITE has 4000+inum1 as the unit number, so I doubt inum1 is 1 at that point! Something you may want to look at.

Steve,

The current message I am now getting is:

forrtl: severe (47): write to READONLY file, unit 4001, file c:SWAT Testworking dir largeautocal1.out

I am stepping through the code from the point of just after the OPEN to see if something is changing the attributes.

Right click on the project, select Properties, Fortran, Command Line. Copy all of the text shown under All Options and paste it into a reply here.

I don't see anything in those options to suggest an issue.

Given the varying symptoms you've reported, I'd suggest you provide Intel Premier Support with the whole program and let us help you that way. I don't think it will get solved in this forum.

Steve,

Everything seems okay now. It seems that even though I installed the later version of the compiler (10.1.019), the old version remains installed and Visual Studio keeps the previous version as the default. I had to go into ToolsIntel FortranCompilers to change the compiler to the new version and then recompile. After that the I/O problem went away.

Thanks for your help.

Yes, that's right. Not a behavior I am fond of... Glad to hear it worked out.
