Switching from py2.7 -> py 3.5 invalidates the .sconsign files contents. You have to do a full build when you make that switch. It's in the release notes somewhere. https://scons.org/scons-300-is-available.html There's no way around it. The best you can do is name your SConsign file to include the python version so at least they won't be invalid when you switch from one to another, but you will see additional rebuilds which may not be strictly necessary. -Bill On Fri, Mar 18, 2022 at 5:03 PM Jay West <[email protected]> wrote: > Yes, our scons-3.1.2 was using python-2.7.17, and our scons-4.3.1 is using > python-3.9.10.
