DLLs and Fortran file unit numbers

[Elizabeth_W_]

Hi everyone,

I'm using ifort 17.0.2 on the command line (via nmake) to compile a Fortran DLL library and executable.

One problem I'm having is the issue of unit numbers being distinct in the DLL and executable.  I've read all the posts I could find on this and the solution was to make sure that the DLL and the executable link to the same run-time library (e.g., both have /MD switch).  This doesn't work for me though.  Is there anything else that needs to be done?  The library and program run fine if I don't do any input/output.

OPEN has NEWUNIT Specifier

Using the same DLL runtime library should have solved this problem. (Using NEWUNIT isn't going to help here.)  What I'd suggest is to download Dependency Walker (http://dependencywalker.com/), run it and open your EXE. It should show that the EXE and your DLL are both referencing the same run-time DLLs.
