Configure failure with libfuse 3.x

[rbberger]

The configure script fails with libfuse newer than 2.x

[hppritcha]

this is an issue on our grace hopper system.

[jswaro]

Please share the result of how it fails with libfuse 3. Libcxi does not currently support libfuse 3 and the team is not actively investigating those changes at this time.

If the delta is small or if someone proposes a PR here, then it could be considered for merge.

FYI, libfuse 2.xx does not compile on arm64 (grace hopper). Howver, this patch for libfuse 2.9.9 resolves the compilation error (found at https://patchwork.ozlabs.org/project/openwrt/patch/[email protected]/)

[hppritcha]

thanks that should do @boeschf .

[rbberger]

@hppritcha in Spack I've submitted this: spack/spack#47846

[jswaro]

Then this can be closed ? @rbberger / @hppritcha

[rbberger]

I would hope this would get closed once libfuse 3.x is supported. What we have are workarounds forcing the use the older version when possible.

[jswaro]

Sounds fine. I'll leave it open, but I do not have an expected date for completion. This is low priority for now.
