fortran dll

[battler.]

Hi all,
I too have fortran source code which I would like to use in LabVIEW.  I have the .for and the .obj files.  I'm not a fortran user.  I've seen that it is reasonable simple to interface directly with Fortran code in MatLab using the .mex functions.  Don't worry I hate MatLab too, although I do have a copy.  If it's so easy to do in MatLab then it has to be even easier in LabVIEW, surely.
Can anyone tell me what to do?
Thanks,
Jay.

Hey Battler,
You could use the Call Library Function Node to do this.
For more information on this, refer to <a href="http://digital.ni.com/public.nsf/allkb/DCB90714981A1F148625731E00797C33?OpenDocument" target="_blank">How Do I Call a Dynamic Link Library (DLL) from LabVIEW?</a>
Hopefully this helps!!

Hi there,
The Call Library function requires that the fortran code be in the form of a .dll.&nbsp; I am not new to LabVIEW (infact I am an ex-employee;-)) but I have no clue when it comes to Fortran or C.&nbsp; I have uncompiled (.for) and compiled (.obj) fortran code.&nbsp; How do I compile into a .dll?&nbsp; Do I need to creat a c code header file (.h)?&nbsp; How do I go about it?
Thanks again.

Hey Battler,
&nbsp;
You'd need to look up how you can convert Fortran to a DLL. Here's link I got from a quick Google search: <a href="http://support.microsoft.com/kb/123841" target="_blank">How To Create a FORTRAN DLL and Call It from Visual Basic</a>
&nbsp;
Once you develop the DLL you'll have to create a C wrapper for LabVIEW to understand the Fortran DLL. A good reference for this would be <a href="http://zone.ni.com/devzone/cda/epd/p/id/4489" target="_blank">Writing a Wrapper Function for an External Code Function</a>.
