COMMON problem

[dray1234]

I am compiling my code using fortran compiler 9.1.

I have a common declaration like:

COMMON /DATE /IM,ID,IY,IFP

Later in the code I do:

IFP=1

This compiles fine with no error but at runtime the program crashes when it reaches the above line.

This program use to work with compaq fortran compiler.

I do not want to convert all the common to modules.

Any suggestion will be highly appreciated.

There's not enough information here. Where is the COMMON declaration? What is the error message? (Access violation?) Can you show a small but complete program that demonstrates the problem?

I am linking the fortran lib through C++ to Java.

A sample program is:

SUBROUTINE crops(STname, NCROP, PMAT, Ploc)

CHARACTER*256 Dir

CHARACTER*256 FileName, tmp

INCLUDE 'comsw1.inc'

COMMON /DATE/IM,ID,IY,IFP

c other initalizations

IFP=1

END

This compiles file with Intel compiler 9.1 but when I call the subroutine there is a runtime error and the program crashes. I checked at the crash is due to IFP=1.

I don't get any stack trace or specific error message .

I only get a JVM crash.

Still not enough information.

Try writing a Fortran program that calls this subroutine and see what it does. I tried an example myself and didn't see a problem. The contents of the include file might also be of interest.

I assume that in your real code there is more to the beginning of the subroutine - DLLEXPORT directives, perhaps?
