[Bug 2060999] Re: Please drop libamdhip64-5 from depends on arm64

[Cory Bloor]

I had to fight a bit to figure out how to build ucx due to the
"debian.upstream" directory, but I've completed an arm64 build. I can
confirm that when autoconf fails to find libamdhip64-dev, it will just
disable ROCm support.

I must admit, I didn't restart my arm64 build after fixing the
maintainer. I do not have access to native arm64 hardware, so I used a
qemu image and it took a very long time to compile.

Title:
  Please drop libamdhip64-5 from depends on arm64

Status in ucx package in Ubuntu:
  New

Bug description:
  rocm-hipamd FTBFS on arm64 in noble due to
  https://bugs.launchpad.net/ubuntu/+source/mumax3/+bug/2032624. It
  seems unlikely that a fix for glibc can be merged in time for noble. I
  will be requesting that the arm64 binaries for rocm-hipamd be removed
  from the archive so that fixes for amd64 and ppc64el can migrate from
  noble-proposed to noble.

  Unfortunately, this will impact ucx 1.16.0+ds-5 as it depends on rocm-
  hipamd. I would suggest that ROCm support in ucx should be disabled on
  arm64, much like it is disabled on risc64. Once glibc is fixed,
  support for ROCm on arm64 can be restored.
