Bug report

I tried to run the command from the terminal and this happened:

/Users/sobolev/Desktop/cpython/Doc/c-api/structures.rst:24: WARNING: Duplicate C declaration, also defined at c-api/structures:24.
Declaration is '.. c:type:: PyObject'. [duplicate_declaration.c]

And then it failed:

build finished with problems, 5 warnings (with warnings treated as errors).
make: *** [build] Error 1

Troubleshooting questions:

What version of Sphinx are you using? Does the error occur when building HTML docs? Does the error occur after make clean venv pydoc-topics?

[mattwang44]

I did not encounter any issue with make -C Doc clean venv pydoc-topics on the current 3.13, 3.14, & main branch (on macOS).

I can't repro this either. Closing.
