Fortran calls Matlab

Fortran calls Matlab

I write a file in Fortran, which calls Matlab engines. I used mex -f xxxx.for to compile the file. However, in matlabibwin32mexopts directory, there is no compiling file for the Fortran version I used (Compaq Visual Fortran 6.6), there is a compliling file df60eng matopts.bat only which is for digital visual fortran 6.0. Can anyone tell me how to write a compiling file for compaq visual fortran 6.6 or just provide me with such a compiling file?
Thanks for expert help!

What is the mex command? Is it something MATLAB provides?

Yes, mex is provided by Matlab. Here's a relevant excerpt from df60engmatopts.bat:

rem ********************************************************************

set DF_ROOT=%DF_ROOT%

set LINK_LIB=
set NAME_OUTPUT="/out:%OUTDIR%%MEX_NAME%.exe"
set RSP_FILE_INDICATOR=@

To me, it seems that linker cannot find dfor.lib since environment variables are not set for some reason. I
think an easy workaround would be to add

set %DF_ROOT%="C:Program FilesMicrosoft Visual Studio"

at the beginning.

can you provide more details? Can you insert that line in the bat file? I tried it, but I may use the wrong format of your sentence. The command is reported to have syntax error.

Yep, I forgot syntax of batch files a bit -- haven't used them for years. Should be just

set DF_ROOT=C:Program filesMicrosoft Visual Studio

That seems to give correct LIB & INCLUDE variables -- didn't try MEXing anything. I think you should've done "Update environment variables" step during CVF setup, but I don't know how to do it at later time (other than re-running the setup).

To add the environment variables systemwide on Windows NT, 2000, Me and (I think) XP, use the program at http://www.compaq.com/fortran/kb/q1038.html to do it. On Windows 95/98, add a call to DFVARS.BAT (found in the DF98BIN folder) to AUTOEXEC.BAT.
