Overall stuart feels kind of alien to linux. It just goes download
stuff from the internet, even in case the tools are already available
locally. Oliver fixed some (but not all) of these when moving CI over
to using containers. IIRC at least the cross compilers are just the
standard fedora cross compiler packages now.
I would like an option to just turn off all the toolchain dependency magic
stuart does. I had a look at stuart and how to implement this but then
did not want to attempt anything without feedback from the maintainers.
For the CI we ended up just plainly deleting the ext_dep files for the
compilers.
While being at it: edk2-pytool-library fails to build with network
access turned off[1] because it tries to download vswhere.exe from the
internet. Even when building on linux.

Fedora build system does that too. We have a patch to make x86 cross
builds work like arm cross builds, by just setting GCC5_${ARCH}_PREFIX
environment variable:

Guess I should submit that one for upstream inclusion ;)

Just use the system-wide tools is the best option IMHO. The packages
are available in Fedora (other distros should be have them too), on both
x86_64 and aarch64, we only need to add them to the CI container image.
So why bother adding nuget builds?
That is also less fragile than downloading them on each CI run and have
checks fail now and then due to network problems.
Is it possible to run github actions (used to build containers) and
azure pipelines on aarch64 systems? So we could move ArmVirt CI from
x86 cross builds to native arm builds?
take care,
Gerd

all sources needed are to produce the binary package are actually
included in the source package.
