Compile Speed on Arduino Portenta

I have a project that is about 10 files, and uses a number of libraries. It can take 3-4 minutes to do a compile, because most of the time is spent doing Deep Search for libraries.

Is this normal behavior.  I have Deep Search for libraries ticked, as I think I require it (read if I have #defines etc in the libraries that perform conditional compiles it is required).

Thanks, 

1)

Please switch to Release for these tests. That simplies the build process so that we can more easily see what is happening. After switching Release build twice and then send the output again.

2)

Confirm what you click to start a build?

I press the Build button, or the one next to it the Build and Run.

Now, debugging with the J-Link - I go through Debug->Start Debugging.


The compile in this case took 9m40s

Thanks for the logs.

Can you restart your PC, and then delete the folder below (and all subfolders and files):
Code
Select All
nvie_m7_mbed_portenta


Then perform two compilations in Release mode, and send us the log from the second (which should be faster than the first)?

Please install the LATEST version. It gives full control over compiler cache and more importantly which folders are searched for libraries.

You should be able to dramatically reduce the subsequent build times.

New releases

There will be more docs published about all the settings but the example settings should make experimentation easy.
