Uninstall avr from.board manager. It's picking up an old tool.chain but using a newer Arduino avr core

Use Arduino ide board manager to uninstall it look in the verbose output and delete the Arduino folder in appdata\local\arduino15\packages

Yes you have a partial install of Ave and Arduino is ignoring it but vm is trying to use it. It's on the list for cm to be enhanced but easily resolved by you.

If not then please submit the usual required build info to allow us to see the full details

Thanks, the output shows you are using ATtiny hardware with arduino 1.6.11

The avr tools have been updated in recent arduino versions

I think attiny was designed for an older tool chain version but because it makes use of files installed with arduino ide it possible to ave the situation where the arduino files contain a new tool chain. In this case visual micro still attempts to use the older tools that are specified for the hardware. Most hardware designers have now stopped declaring a "required version" when they are inheriting tools from the arduino. That's the cause of the confusion but visual micro could ignore the stated version and use the tools with the ide instead of the ones downloaded. That's what arduino is doing.

To give more clarity I would need to see the verbose build output where as your link only shows the build properties. 

Solution

Delete the following folders to clean up your installed hardware folder, then restart the ide.

C:\Users\TEST\AppData\Local\arduino15\packages\arduino\tools\avr-gcc

Questions

When did you update the arduino ide last?
When did you install the Attiny core?

I am trying to understand the order of installation.

Thanks

and when I deleted the said folder, I got this error
http://pastebin.com/HYcJG63E

I dont remember when I last updated the arduino, but I installed attiny core 2 days ago. It all works fine in Arduino IDE.

If you put that folder back or reinstall the attiny then in visual micro switch the tool bar from arduino 1.6/1.8 to "Visual Micro" it should work okay.

The "Visual Micro" option ignores the arduino ide config and uses whatever you have installed in board manager. less room for confusion. That should be a short term workaround.

There is no option for "Visual Micro" in that combobox, its just Arduino 1.0 and Arduino 1.6/1.8

That means you are using an old version of the product. You can see new features in the release notes

When using the visual micro option you need to make sure you have installed the tool chains you require. Your attiny needs an arduino avr toolchain so I suggest installing the latest arduino avr which i think is 1.6.18

Then click the rescan button

Thanks
