Tests are passing (🎉), but wheel builds are failing. @alugowski do you have a moment to take a look?

Tests use the library built by conda, wheels build it ourselves. Looks like there are differences.

Linux error:

  ../venv/lib/python3.9/site-packages/suitesparse_graphblas/__init__.py:7: in <module>
      from ._graphblas import ffi, lib
  E   ImportError: /tmp/tmp.kWfsLrL72N/venv/lib/python3.9/site-packages/suitesparse_graphblas/../suitesparse_graphblas.libs/libgraphblas-c7173593.so.9.4.2: undefined symbol: GB__Adot2B__plus_firstj_int32

Seems related to this point in the release notes for upstream 9.4.2:

  • removed Factory kernels for: types int8 and uint8, and semirings:
    max_min, max_plus, max_times, min_max, min_times, plus_min, plus_max,
    non-Boolean land/lor/lxor/lxnor, and integer times_first/second,
    to reduce size of compiled library. JIT kernels will be used instead
    for these types and semirings.

Does that mean the library needs to be built differently? Or cffi needs to be updated?

We don't have the JIT, so if someone uses those JIT-only kernels then something appropriate needs to happen.

Sounds like the directories where GraphBLAS puts things changed yet again. Someone needs to track down the new include directory on macos and make sure the build system looks there. IIRC the include search path is around here:

python-suitesparse-graphblas/build_graphblas_cffi.py

Windows failure appears to also be the undefined symbols to the no-longer-included kernels.

I didn't move the location of GraphBLAS.h. Also, the library still has GB__Adot2B__plus_firstj_int32:

$ nm -gD libgraphblas.so.9.4.2 | grep Adot2B__plus_firstj_
0000000001752b00 T GB__Adot2B__plus_firstj_int32
0000000001752b70 T GB__Adot2B__plus_firstj_int64

So the error you're seeing is not related to any symbols I removed.

I did remove the built-in int8 and uint8 types from most of the FactoryKernels, to reduce the compile time and library size. These are all that are left for uint8:

GraphBLAS will still compute the correct result for uint8 and int8 types. It will either use the JIT if that's available, or if not, it will use the generic kernels. Those are slower but they still work just fine.

I don't know if this is related: When I saw you were having these errors, I thought I would try some more testing of GraphBLAS 9.4.2 by updating the main SuiteSparse repo with this version (I hadn't done that yet). The SuiteSparse repo has an extensive cross-platform CI.

I encountered some errors because 10 semirings got inadvertently defined twice in GraphBLAS.h:
DrTimothyAldenDavis/GraphBLAS@196a2aa

It's a quick fix, but I'm not sure if this problem is related to yours.

These extra definitions only cause problems if GraphBLAS.h is #include'd in a C++ program, since one set of the duplicate definitions was inside an extern "C" {...} block and the other wasn't.

I'll release a GraphBLAS 9.4.3 shortly -- probably by tomorrow (Dec 20).

@DrTimothyAldenDavis it looks like it might be related.

The Windows build has a better error message. Linux fails at library import while Windows fails earlier at the GraphBLAS link step and lists all the missing symbols, not just one.

See full list in the Actions output: https://github.com/GraphBLAS/python-suitesparse-graphblas/actions/runs/12404089168/job/34628708451?pr=136#step:9:3393
