Link error when compiling for 'Arduino/Genuino Uno'

Hello,

When I start a new Visual Micro Arduino project in visual studio 2019, I get a link error when I compile the empty sketch.
With a empty sketch I mean a empty setup and loop function.

See the attachment for the output.

If I compile the sketch for other boards than the 'Arduino/Genuino Uno' it compiles without any problems.

What do I miss?


Best regards, Lonoriel

I don't see this on my machine at present, could you confirm the below information:

The same sketch works for the Genuino/Uno when compiled in Arduino?

The Arduino IDE version installed?

Found a solution for my problem, when I change the IDE from 'Arduino 1.6/1.8' to 'Arduino 1.9 (beta)' it compiles again.

When I run the empty sketch in Arduino IDE it compiles fine.

Glad its working for you, can you confirm which IDE is set in the  'Arduino 1.6/1.8' and 'Arduino 1.9 (beta)' windows?

I'm not sure if I understand the question but within visual studio -> vMicro 
I changed the IDE from 'Arduino 1.6/1.8' to 'Arduino 1.9 (beta)' and then it compiles fine.
If I change it back to 'Arduino 1.6/1.8' I get the link error again.

Few questions

1) What IDE paths show for Arduino 1.6/1.8 and for Arduino 19 beta
2) Does the problem happen if the toolbar is set to Release instead of Debug
3) Does the problem happen after clicking "Build>Clean Solution" and then Building.

Thanks

1. Path is set to 'C:\Program Files (x86)\Arduino'
2. It builds in release (for 'Arduino 1.6/1.8')
3. After a Buid->Clean Solution it does build too.

Thanks for helping me out, back to programming again Smiley

Thanks for the update.

Can you please confirm that after the "Clean" the build also works when the toolbar is set to "Debug" ?

and can you confirm that you recently updated the Arduino IDE version?

I can confirm if I switch it back (from Release) to Debug and do a clean it works too, bit embarrasing.
I updated the Arduino IDE to the last version yesterday.

Thanks for your time.

Thanks. You should not need to click build>clean under normal operation. Only if you encounter a strange compile problem.

Normally Visual Micro handles this without need for clean. 

Do you recall which version of arduino you had installed previously?

Unfortunately I can't recall what the previous version of the IDE was.
