So I installed v2.0, and then imported a project which successfully built in v1.13.1.

The v2.0 build fails at the first compile:

The problem seems to be the single quotes around the weak & packed definitions - where are they coming from?

They aren’t being added to USE_HAL_DRIVER or STM32L476xx - and the settings seem identical:

So what’s going on ??

EDIT

If I remove the __weak and __packed definitions from the Project Properties, then their -D entries no longer appear on the compiler command lines, and everything builds fine.
