ADIOS 2.11.0 DILL CMake issue on macOS GH Action Runners

[ax3l]

In openPMD/openPMD-api#1833, I am trying to build an all-static build of openPMD-api dependencies, including ADIOS2.
I am updating that build logic from ADIOS 2.10 to 2.11 right now.

My Linux builds are all good. Using the exact same build logic, but on macOS-14 arm64 and macOS-15 x86_64 GitHub runners alike, I get the following error from just updating from 2.10 to 2.11:

attn @eisenhauer @pnorbert @vicentebolea please help :)

[eisenhauer]

Hey @ax3l ! Lots of CMake logic changed here, trying to make dill optional where it wasn't available. Not sure why it's going badly in this situation yet, but I'll dig into it on monday.

[ax3l]

Thanks, Greg! Let me know if my build options are weird or something, hope it's easy to spot :)

[ax3l]

Hi Greg @eisenhauer, any news? :)

[ax3l]

@vicentebolea do you see similar problems with ADIOS2 superbuilds with DILL in your Kitware build stack?

[eisenhauer]

Hey @ax3l ! I should have dropped a note. I have significantly revamped the CMake in all the GTkorvo software stack and that is now pulled in and merged with ADIOS master. Can you retry and see if your issue still exists?

[franzpoeschel]

I have pulled in the current master of ADIOS2 and the issue seems to still exist

[eisenhauer]

OK, I have a theory. It looks like DILL isn't being built at all, which should be fine for the current version of FFS, BUT the thirdparty/ffs/CMakeLists.txt in ADIOS has "set(FFS_USE_DILL ON CACHE INTERNAL "")", which means that FFS will always think that it found DILL, and then we get the weirdness above. If I'm right, then I think the solution is to change that unconditional line to be conditional. I.E.
if(TARGET dill::dill)
set(FFS_USE_DILL ON CACHE INTERNAL "")
else()
set(FFS_USE_DILL OFF CACHE INTERNAL "")
endif()
Can you test this easily with a patch, or would you like me to put in a PR to master or release_211?

[franzpoeschel]

I have enqueued a run that tests this, thank you. Will check on Monday if it has worked.

[ax3l]

Thank you @eisenhauer, yes if you can open a WIP PR to release_211 then we can test and iterate on that.

[ax3l]

Hi @eisenhauer , we tried the patch and it's still the same error.

[ax3l]

Note that we use

-DCMAKE_DISABLE_FIND_PACKAGE_LibFFI=TRUE

in our build logic.
Does DILL require libFFI or is it optional?

Trying now -DFFS_USE_DILL=FALSE as CMake argument.

[eisenhauer]

Yeah, I saw the disabling of FFI and that's likely why DILL is deciding not to build. That version can't do dynamic code generation on MacOS, and while it can do emulation, it needs libFFI to do that. I'll do some more digging here, but the other thing that I'm working on is getting DILL enabled on MacOS. I've got that working in the package, but haven't pulled it into ADIOS yet (and not sure we'd want to pull it into release_211 because of the massive changes).
Kind of hopefull that your FFS_USE_DILL=FALSE might work.
