My Alma 8 system doesn't have it at all outside of pkgsrc.  Which raises

Yes, we don't want to depend on the "system" libraries on Linux.


Is this a naming misunderstanding?

My understanding of the various "system" configure args out there is
that they boil down to "something already present, do not build the
embedded one in my own distribution". In pkgsrc context "system" would
be pkgsrc, not the base system or some other package management.

That's a good question.  My notion of what "system" usually means is the
same.  I have not picked apart the rust build system in order to figure
out what it means to rust, but for whatever reason, it fails to find the
pkgsrc libunwind when enabled (at least on Linux).  I'll update the
comment before committing the workaround to better reflect this.  Maybe
there's a better solution to be found, but the package is broken on
Linux right now, so I wouldn't want to delay some sort of fix much longer.


I think this has to do with the platform specific unwinder linkage
selection logic which you can find in library/unwind/src/lib.rs.

If I read this right, then libunwind is not being dynamically linked by
this module on NetBSD which explains why we don't see an issue there.
In the Linux case it tries to use libunwind dynamically, but it is outside
of the system's default search path when using pkgsrc. Providing library
paths to rust code is not straight forward. Something like this might
work assuming it will get the correct run path as a side effect of
linking with llvm.

This leads to a different error on Lubuntu 23.10, shown below.  Any
objections to patching out --llvm-libunwind=system for Linux as a
temporary workaround?  It will be documented as such.
