Always recompiles all code including libraries after updating to latest vmicro (Read 771 times)

	I couldn't figure this out. After updating to latest vs2019 and vmicro (purchased support for another year) my project always compiles everything again which slows things down greatly. I saw folks had issues with this before so I deleted my solution and recreated the solution with my source files. Same issue. I deletedthe temp vmbuilds and vmcore in my Appdata as well as the .vs in my solution. Same issue. To test if it was working, I then created a new test solution and compiled and recompiled and its NOT recompiling the libraries again. So there is somewhere a configuration that is not picking up the precompiled libraries for my solution. Attached is the build output text file. Any help appreciated as its really really slow.

	Thanks for the report and the log. The root cause of the libraries being recompiled every time is the name of your Project (and main INO File) has spaces in it. You can resolve this by right clicking the INO file in Solution Explorer, and rename it to remove the spaces, and click OK to the popup. The project will then reload, and the first compile will be a full one again, however after this it should use the cache as expected.

	Awesome! That worked. It used to accept spaces in the name but I guess that changed at some point from the last version I had to this latest version. Thanks!

	Please install the latest release (2024.1211.0) from the top of the below board, this should resolve the caching issue even if there are spaces in the name: https://www.visualmicro.com/forums/YaBB.pl?board=VS_ARDUINO_EXT_RELEASES

	Awesome, this got my Teensy 4.1 project from 60s down to 10s when there was no change in the files (using Visual Studio and having a non-standard code structure). Thanks for the effort and keep the spirit! Best Regards Daniel
