Problem in watching value in debug mode of fortran code in Visual studio 2019

Ani_mondal_2020 — Wed, 16 Dec 2020 23:00:28 GMT

I am running my fortran code on Intel visual studio 2019 using Intel fortran compiler. I want to watch the value of any variable inside the code, lets say, value of the variable gap within the file named PD_ph_f_cera_fort.f90, after applying a breakpoint at gap. But I am failing to watch the value and it is showing the error: identifier "gap" is undefined inside the watch window below. Can you please guide me finding why am I facing the issue and how can I watch the value after applying breakpoint in debugging mode?

I am attaching three things with this mail for your convenience:

snapshot of the microsoft visual studio screen after pressing start button with debug mode.jpeg

Waiting for your valuable reply as early as possible.

Please ask me if you have any queries.

Thanks in advance

That the variable name shows as lowercase tells me that the Fortran debug integration isn't being used. Try an uninstall and reinstall of the Intel compiler.

After re-installing Intel Fortran compiler(Intel Fortran Compiler(Beta) for Windows), the same problem exists. I have installed the following files apart from Microsoft visual studio 2019 to run and debug my Fortran code from the site (https://software.intel.com/content/www/us/en/develop/articles/oneapi-standalone-components.html#fortran

Intel Fortran Compiler(Beta) for Windows
Intel Open Volume Kernel Library for Windows
Intel openAPI Math Kernel Library for Windows
Intel oneAPI Data Analytics Library for Windows
Intel Inspector for Windows

I have downloaded all files from installer 'Local'.

Can you please tell me that all the files mentioned above are required to install or not to watch the value in debugging mode? And also guide me if any other files are needed to be installed from any other source to solve my purpose.

Why are you installing the beta? The oneAPI HPC toolkit (with Fortran) is released.

After installing oneAPI HPC Toolkit with openAPI Base Toolkit, my problem has resolved. Thanks!

I have the same problem. I can not get the debug watch information.

I have installed the toolkit

My visual studio version is 2019 version 16.8.4.

See the below. I create a simple program, but I cannot watch the information.

Please show a screenshot of the Locals window.

the problem is solved for now after I unstall and reinstall everything, VS, base and Hpc.

I have the same problem after I installed oneAPI. Does it really the only solution to install again everything?

It was helpful to set the compiler optimization option as Disable.

: Solution explorer -> Fortran project -> Properties -> Fortran -> Optimization

With options like /O3, breaking points worked, but values of variables were not available for watch.

I have the same issue with recently installed (upgraded from 2019) MVSC 2022, Intel Fortran compiler 2023. I also installed the Intel oneAPI HPC Toolkit with openAPI Base Toolkit. When I scroll over variables during debugging I used to see the values in MVSC 2019, now nothing is shown. Screenshot of Locals below:

Is your call stack in the focus of the procedure with those variables?

IOW, if your procedure with those variables, called a library procedure, and that errored .AND. EPS1 and EPS2 were global variables, then you might see what you have shown.
