Hi,

It's important to distinguish if we are looking at an intellisense issue or build issue.

Please follow the guide in yellow at the top of this page so we can see which tool chain and other info.

Thanks

Thanks for the verbose output. I tried the project you posted (test2) in your first link and it builds OK but is too large. I see the same error in arduino and visual micro that the program size is too large.

Please post screen shot of errors you see?

Code:

Program too big. The size is 1357686 bytes (of a 1310720 byte maximum). Ensure debugging is OFF and/or see http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing it.
Debug build failed for project 'AG_GPS_ROOF_UNIT_ESP32'
 

Test1 has built correctly - OK
Code:

Program SerialCallResponse size: 200.612 bytes (used 15% of a 1.310.720 byte maximum) (4,00 secs)
Minimum Memory Usage: 13500 bytes (4% of a 327680 byte maximum)

# Copy build result to 'Project>Property Pages>Intermediate Directory'
# Destination: file:///C:/Program%20Files%20(x86)/Arduino/examples/04.Communication/SerialCallResponse/Release/ 

Hi,

I think the confusion is that in Visual Micro you are seeing some intellisense errors. We can look into these but the compile is working okay. You can see that when you click the compile button.

It is important to understand that there is a difference between intellisense errors and build errors. Visual Micro handles the build but leaves visual studio to handle the intellisense.

We can feed additional information into intellisense which will improve things for you but it is important first to see that when you click Build in Visual Micro everything is working the same as the arduino ide. I can see in the two files you posted that the build is working correctly.

One thing that will help is to set the drop down list at the top of the "Errors List" to "open documents only" or to set the  drop down list at the top right of the Errors List to "Build Only". This will be less confusing until we look into the intellisense problem.

Does this make sense?

What is the version of visual micro you are using? You can see this in Tools>Extensions and Updates

In your screen shot I can see intellisense errors which are because you have spell check enabled.

Can you please post a picture of code or the errors list showing the intellisense errors you are referring too?

Thanks

If you switch the drop down list at the top of "Errors List" from "Intellisense + Build" to "Build Only" it might be better for now.

I'm not seeing some of the errors you can see, the ones in red are okay for me. Hopefully you have built the new project because that will help but I can tell you it might not be perfect until we move to a new intellisense system Microsoft are in the processes of releasing.

Try to ensure you are on the latest vs2019, Microsoft are improving this area all the time.
