[Bug 2099792] Re: [p-m] FTBFS on all arches due to CMake dependency limit

[Tim Andersson]

This is fixed upstream *upstream*:
https://github.com/bpftrace/bpftrace/blob/master/CMakeLists.txt#L161

And you can see a portion of the work required to build successfully with LLVM 20 is here:
https://github.com/bpftrace/bpftrace/commit/3659538df0c4cad0abdd295a43a19bd2b643b35f

My suggestion would be to wait for debian, and then in turn ubuntu, to
get these changes from upstream.

We just need a new release upstream of bpftrace
https://github.com/bpftrace/bpftrace/releases

The next release is scheduled for 25th March, 2025:
https://github.com/bpftrace/bpftrace/blob/master/docs/release_process.md#upcoming-
release-schedule

Title:
  [p-m] FTBFS on all arches due to CMake dependency limit

Status in bpftrace package in Ubuntu:
  In Progress

Bug description:
  The version in plucky-proposed rebuilt against llvm-20 FTBFS with the
  following CMake error:

  CMake Error at CMakeLists.txt:155 (message):
    Unsupported LLVM version found via /usr/lib/llvm-20/include: 20

  
  CMake Error at CMakeLists.txt:156 (message):
    Only versions between 6 and 19 are supported

  A starting point would be to test a build with a bump to 20, but I
  suspect it will need more than that.
