Re: Building with local Python3 etc
Thanks Jon and Jonatan!
I think we are only a little bit away from having this work well for
developers who want to have fast local incremental builds, packagers who
need robust from-scratch relocatable redistributable builds, and users who
want signed and notarized builds with Python 3.
The aim is that developers will be able to use a system Python and not need
to make install or run wrangle-bundle, and that the CI builder will produce
signed, notarized builds and upload them to the CERN download servers.
The CI builder part is already producing signed builds, and I've uploaded
notarized and signed ones to osx/testing.
The next steps on improving the developer experience is to make sure folks
can use a system Python, and then to make sure that devs don't need to make
