Library Compilation

I see this is on another thread but there was no conclusion. 

I've created a fresh, simple project intending to enhance it. But I notice that the libraries are compiled every time. With a simple project, this adds only a few seconds, but bigger projects are taking as long as 70sec to build.

I'm sure it didn't do this before I recently upgraded.

The build log output is attached.

you need to have the verbose compile enabled on the vmicro menu. The build detail is missing from your attachment.

Here you go.

On inspection. it seems to use previously compiled things for some, but not all, libraries.

Can you confirm if you upgraded any libraries recently (e.g. SDFat) and if so was this done manually from ZIP files or using the Arduino or Visual Micro IDE?

Yes, I upgraded sdfat using a zip file.

Thanks for confirming, that could explain some of the oddities we are seeing in the logs.

When you installed the Teensyduino software, did you also install all libraries with it? 
(If so there is a version of SDFat, Time, FlexCAN, Meto and Adafruit_NeoPixel already available in C:\Program Files (x86)\Arduino\hardware\teensy\avr\libraries)

If you run Build > Clean Solution, and then build your project again, and then again, it should cache all of the files.

If it does not, it may be the Sketchbook\libraries are not correctly deployed (e.g your SDFat library shows v1.0.7 but has files in the log which were introduced in v2.x).  If these are moved elsewhere, the ones installed with Teensyduino will be used instead.

Thanks.

I did that, but the libraries still compile. 

I am using a relatively old version of Teensyduino/Arduino because the newer version have a later GCC complier which is not as efficient as the old one. This wouldn't normally matter but one of my widely deployed things uses 96% of the available space in a Teensy and the later compilers won't fit it in.

This is also why I can't/don't install the libraries with Teensyduino. It deploys the latest, which sometimes are not backwards compatible with the old (SDFat is a good example) and usually have increased sizes meaning that they compromise the code.

Thanks for the update.

I assume the optimization options (e.g. Smallest) don't help with the newer compilers?

Can you confirm it is the Teensyduino 1.5.7 version in use? (The log suggests this but want to be 100%)

Can you try deleting the Sketchbook\Libraries\SDFat folder, and then unpacking the ZIP copy again, and then doing the clean build again.

After this please attach the build output again so we can review again with the clean library and build folder?

I found the optimisations tended to miss out bits of code and the application requires real-time monitoring of certain things.

TeensyDuino is 1.57

I deleted, re-installed manually, cleaned, built and re-built and here would be the log, except the attachment box has disappeared. I'll email it.

Please install the latest release (2024.1211.0) from the top of the below board, this should resolve the caching issue:

Thanks!!!

Works a treat. Subsequent compilations on my example were 40s. Now down to 6s, so problem solved Grin
