I am trying to install frama-clang on Ubuntu 22.04. I have frama-c v28.1 installed and working, and all the dependencies, camlp5v8.02.01, clang v14.0.0-1ubuntu1.1, opam v4.13.1, and cmake v3.22.1.

When I install with opam install frama-clang, I get the following error:

The following actions will be performed:
  ∗ install frama-clang 0.0.15

<><> Processing actions <><><><><><><><><><><><><><><><><><><><><><><><><><><><>
⬇ retrieved frama-clang.0.0.15  (cached)
Processing  2/3: [frama-clang: dune build]Killed

When I install from source, I get a very long error:

~/frama-clang-0.0.15$ make

I must not crash.  Uncertainty is the mind-killer. Exceptions are the
little-death that brings total obliteration.  I will fully express my cases. 
Execution will pass over me and through me.  And when it has gone past, I
will unwind the stack along its path.  Where the cases are handled there will
be nothing.  Only I will remain.
make: *** [Makefile:41: build] Error 1

I have tried make clean, and expected a more informative error on which dependency was missing.

Has anyone seen this before or know how to fix it? Thank you for your time.
