How to obtain an executable file from a Fortran code with MATLAB mex

[yang__rui]

Hi all,

I have a code containing MATLAB mex functions (enabling "calling" MATLAB files). It works well with the "debug" configuration, but I want to convert it into an executable file which allows me to use it without visual studio. I tried to change the configuration into "release" to get the executable file, but there are a lot of errors with the MATLAB mex part. It would be very helpful if anyone can tell me how to obtain this exe file.

Thank you!

The environment is: 64bit win10;  Intel parallel studio XE 2017fortran + Microsoft visual studio 2017.

Are you missing some lines in your program?   The first three messages indicate that there are preprocessing lines (beginning with the character "#") but none show in the code you have posted.

"swpointer" is not a valid Fortran construct, nor is "swsize"

Let me guess that the missing lines look something like this:
#define swpointer integer(kind=int_ptr_kind())
#define swsize integer

If my guess is true, then you need to mark the RELEASE configuration use the preprocessor, as you did for the DEBUG configuration.

Hi Lorri,

Thank you so much! Yes, I need to reset the preprocessor and other options, and then the problem can be solved.
