A URL isn’t resolving early in the build process.
The same flow works for v5.2.0 but not for v5.3.0

Looking at a recent guide here, there are some differences in the build zechub/RaspberryPi4FullNode.md at main · dismad/zechub · GitHub
such as "

sudo apt-get install gcc-aarch64-linux-gnu

Next change directory into the freshly downloaded zcashd release and run:

HOST=aarch64-linux-gnu ./zcutil/build.sh
"
I’m not sure if this is why it’s 404’ing 4 U but I would suggest following it and trying again, see if that doesnt work.

Thank you for the response. I believe all of those highlighted differences are relevant only for cross compilation. I’m trying to build locally on the Pi (I know, its slow).

The compilation works fine for v5.2.0 without having to

  • install g++-multilib (unavailable on the pi anyway)
  • install gcc-aarch64-linux-gnu
  • specify HOST=aarch64-linux-gnu

…so I think there is something else amiss.

I’m following this guide which does include a 5.3.0 reference so has been updated recently.

Sorry, @opacey. Our aarch64-linux builds in CI, etc. are all done via cross-compilation, so we missed this. Another user submitted a PR for this already, so you can try their branch, or wait for it to be merged (which should be soon): fix aarch64 dependency native clang download URL by 0xidm · Pull Request #6255 · zcash/zcash · GitHub

Hope that helps!
