Visual studio watch does not show module variables using ifort classic

ata_mesgarnejad — Mon, 28 Aug 2023 18:03:41 GMT

Hi,

I'm unable to debug/watch a variable defined in the module. In the watch window they are being shown as undefined and I get a similar error if I try to add them to a breakpoint condition. I have attached the minimal example replicating this issue.

I'm using

visual studio 2022 (17.6.5) and intel Fortran Compiler Classic 2021.10.0

PS: The watch works correctly for ifx.

I find it interesting that ifx does this on its own. With ifort, you needed to use modname::varname in the watch window for module variables.

Thanks, Steve. That works.

I want to add that hover over module variables still doesn't work! It would be nice if you could restore that behavior back as well.

Dear Steve,

Unfortunately, this solution does not work for me. Due some restrictions, I have to use Fortran 77 without extension.
Wrapping the variable is not an option in my situation.

I need to be able to watch a variable while debugging.

Presently, if I add a variable in the watch list, Visual Studio display a pop-up window about trying to display the value. Visual Studio hangs there... then crashes.

I did not have this problem with Fortran 2019 and Visual Studio 2017.

Any other suggestions to solve this issue?

Regards,

Hi,

I have been having the same issue with variables watch hanging since updating to Visual Studio 17.7 from 17.6. I'm going to downgrade for now until this issue is fixed.

Best,

Ata

A recent topic discusses the new VSIX file to update the latest VS programs. If you search you shall find it.

Apply the VSIX and Bob's your uncle.

Thanks, John. I believe this is it.

Does it hang when you use the correct variable name?

It did hang for me Jim whether I used the variable name or module_name::var_name. I have a screen shot of a super minimal example above.

Yes, I believe that is correct.

One learns many valuable lessons in life, that was not one of them, but perhaps.

I first started using ULARC in 1981. I compiled on a CDC machine at the time from a tape recording from UCB. My boss did a masters at UCB.

In all that time and with a lot of analysis I had never had a stop error on maxl exceeded by the model. I had to add line 39 and increase sk.

It just happened.

It took a few minutes in the VS 2022 preview using the new VSIX stuff to work out the problem was the biggest I have run - ever.

It is only 125 members.

They were limited in the olden days.
