Is soda-core-duckdb compatible with GraalPy?

[vprotsiv]

I'm trying to use soda-core-duckdb with GraalPy . However, the installation of the duckdb dependency fails during compilation with the following error:

...
 -I/Users/vprotsiv/.pyenv/versions/graalpy-24.2.0/include/python3.11 -c duckdb_build/ub_src_core_functions_scalar_string.cpp -o build/temp.macosx-15.4-arm64-graalpy242-311/duckdb_build/ub_src_core_functions_scalar_string.o -std=c++11 -g0 -stdlib=libc++ -mmacosx-version-min=10.7
[error]    error: command '/usr/bin/g++' failed with exit code 1
[error]    [end of output]
[error]
[error]  note: This error originates from a subprocess, and is likely not a problem with pip.
[error]  ERROR: Failed building wheel for duckdb
[info] Failed to build duckdb
[error] ERROR: Could not build wheels for duckdb, which is required to install pyproject.toml-based projects
[info] Python environment setup complete.

Is soda-core-duckdb expected to work with GraalPy?
Are there any workarounds?

Hi. We have never tested it, but I could install duckdb just fine on 24.2.1. Can you post the whole build log?

Hi @msimacek , I've shared the log in the comment above. Btw, I had the same issue on 24.2.1

The actual error seems to be this:

[error]       In file included from duckdb_build/ub_src_core_functions_aggregate_distributive.cpp:3:
[error]       duckdb_build/src/core_functions/aggregate/distributive/arg_min_max.cpp:167:20: error: a template argument list is expected after a name prefixed by the template keyword [-Wmissing-template-arg-list-after-template-kw]
[error]         167 |                         STATE::template ReadValue(finalize_data.result, state.arg, target);
[error]             |                                         ^

That is not a problem with GraalPy, but with compiling the source in general. It seems that recent versions of clang are more strict with regards to some C++ template syntax. I found some blogpost that mentions exactly this problem when building duckdb from source: https://www.stoutpanda.com/posts/building-duck-db-on-ubuntu/
You can try setting CXXFLAGS="-Wno-missing-template-arg-list-after-template-kw -Wno-writable-strings" (just a guess, I couldn't reproduce the problem even with my version of clang, so I don't know if it really helps) or switching the c++ compiler to gcc's g++.

The problem was solved by setting CXXFLAGS="-Wno-missing-template-arg-list-after-template-kw -Wno-writable-strings".
Thank you
