It cannot be the same as the _PRIMAL_STATUS_MAP because for Lib.TERMINATION_REASON_PRIMAL_INFEASIBLE, the dual status should be MOI.INFEASIBILITY_CERTIFICATE

I actually had the same issue and it prevented me to run it locally, for me, it seems to be because I have CUDA v13.0

julia> CUDA.versioninfo()
CUDA toolchain:
- runtime 13.0, artifact installation
- driver 580.105.8 for 13.0
- compiler 13.1
and cuPDLPx is only available on CUDA up to v12.9:
https://github.com/JuliaBinaryWrappers/cuPDLPx_jll.jl/tree/main/src/wrappers
The issue seems to be this line:
https://github.com/JuliaPackaging/Yggdrasil/blob/96df50e83da84ec3a4c48b4d9360abaa9c5a843d/C/cuPDLPx/build_tarballs.jl#L51
If you can run it locally and show me test errors here I can help. Otherwise, if the jll is fixed for CUDA v13 then I will be able to run the tests locally and it should be more efficient

Thanks a lot! I’ll update build_tarballs.jl to add CUDA 13 support.
For the const libcupdlpx = "/home/zdpeng/.julia/artifacts/..." workaround: I asked Gemini and it suggested changing LibraryProduct("libcupdlpx", :libcupdlpx), to LibraryProduct("cupdlpx", :libcupdlpx), in build_tarballs.jl.
Do you think that makes sense here?

I'm not an expert in BinaryBuilder but looking at the docs, the libname should be libcupdlpx here:

Hi @blegat, thank you very much for your help with the MOI wrapper.
Following your instructions, I’ve tested the MOI wrapper. Could you please take a look at the implementation when you have a chance?
The tests are now able to run, although some currently fail due to issues in cuPDLPx itself. I’ll update the source code to fix these shortly.
