Unable to install dedupe

[mackenziedott]

I'm able to install the python library dedupe in a conda environment, but am unable to succeed in uv.

Command: uv add dedupe (or uv pip install dedupe)

Log:
error: Failed to prepare distributions Caused by: Failed to fetch wheel: dedupe-levenshtein-search==1.4.5 Caused by: Build backend failed to build wheel through build_wheel()` with exit status: 1

    With Python 2.7 end-of-life, support for building universal wheels
    (i.e., wheels that support both Python 2 and Python 3)
    is being obviated.
    Please discontinue using this option, or if you still need it,
    file an issue with pypa/setuptools describing your use case.

    By 2025-Aug-30, you need to update your project and remove deprecated calls
    or your builds will no longer be supported.

running regular pip install dedupe succeeds, but uv sync will of course erase the package.

uv version = 0.4.0

Does setting CC=gcc CXX=g++ fix this?

[mackenziedott]

It does! Thank you for the help!

Another case of #8429 / #8036. We're tracking over there. Sorry about that!
