Build failure on MacOSx (M2) Sonoma

[DeniseWorthen]

I didn't want to create an issue, because most likely this is user-error. I decided to see if I could build spack-stack (ufs-weather-model environment) on my home platform. My platform is new and very clean. I did a selective migration from my old Intel machine.

I started at 6.1. I was able to follow the instructions through to the Section 10. I did not do anything under Section 9.

For the concretize, I see some items marked with [e]. I don't know if that indicates an error, but I got through that step. At the next step (install), it failed with the last thing in the build-out showing

checking for on_exit... no
configure: WARNING: neither statfs() and statvfs() were found
configure: error: Cannot continue

You may be hitting this: #971

@climbfuji Yes, thanks, that certainly seems related. It's difficult for me to follow what has been merged or still needs to be merged. There is a comment that jscda/spack-stack/977 has been merged, and that it may fix the issue. I have that commit in what I was trying to build (b7b36e0).

Can you try to set these flags globally in your spack compiler config?

LDFLAGS="-Wl,-ld_classic"

See https://spack.readthedocs.io/en/latest/getting_started.html#compiler-config

I agree to try setting LDFLAGS as @climbfuji suggests.

If that doesn't work, @fabiolrdiniz got it to work on his Mac with this edit to the openmpi/package.py script: #971 (comment)

[DeniseWorthen]

Add the ldflags (I manually edited the site/compilers.yaml) as suggested by @climbfuji worked. At least the the install reports success, I haven't tried to use it yet.

One thing I found is that it did not seem to work to try to "rebuild" in my previous env, so I created a new one. Is there a "right" way to clean an env ?

[climbfuji]

I think you have to force a re-concretization for the new flags to be effective
