Description
When installing immutables==0.21 in a Python 3.14 environment (via Pixi
or pip), the build fails because there are no prebuilt wheels for Python 3.14, causing a fallback to source compilation.
Error log:
× Failed to build immutables==0.21
╰─▶ Call to setuptools.build_meta.build_wheel failed (exit status: 1)
building 'immutables._map' extension
error: command 'gcc' failed: No such file or directory
Environment:
- Python: 3.14
- Package: immutables==0.21
- Platform: Linux (x86_64)
- Tool: pixi (similar to pip/conda)
- Works fine on: Python 3.13

Research direction
Reproduce the installation of immutables==0.21 with Python 3.14 using Pixi or pip on Linux, and compare it with Python 3.13. No source file or test is named; investigate the packaging and wheel-build entry points, with success defined as a working Python 3.14 installation without the reported build failure.
