I have a 4K program (source code). It is taking over 15 minutes to compile before downloading to the board. I imagine this is not normal. Under Arduino 1.6 it takes less than a minute.

Is there something that I could be optimizing?

Thanks for the output.

As you say it always performing a full build which isn't normal.

Please ensure that tools>options>visual micro>compiler optization has true for both settings (core and libs). True is the default setting for both.

If they are both True then the problem must lie with project properties

View the visual micro properties of the current project and ensure the following defaults are still set:-

> Micro Optimise Build (Project Global)

Compare dates and times = true
Mcu defines affect core = true
Mcu defines affect libs = true
project defines affect core = false
project defines affect libraries = true
source defines affect libraries = false

Hi,

Don't change any options you are right the defaults are correct.

Don't use Rebuild because it does as its name suggests. Rebuilds

Please send a verbose output when you do not press Rebuild. Just the normal Build is fine.

Thanks

Hi,

We believe the speed issue is related to your virus checker software. The visual micro build folder can be excluded if that was the issue.

Your compile times should be just a few seconds.
