Hi,
I’m using sip to generate some Python bindings to PyQt. Our build environment adds \
-Wextra to the compiler flags and this seems to generate warnings about missing field \
initializers when compiled with clang.
I have managed to reproduce this using the basic example at \
https://www.riverbankcomputing.com/static/Docs/sip/examples.html#a-standalone-project, \
adding
[tool.sip.bindings.fib]
extra-compile-args = ["-Wextra"]
to the pyproject.toml. Building this with `sip-build` on macOS with clang-13 produces \
the following warnings:
These bindings will be built: fib.
Generating the fib bindings...
Compiling the 'fib' module...

^

warning: missing field 'em_exception_handler' initializer \

^
2 warnings generated.
The project has been built.
I can disable the warnings in my code but could there be an underlying issue here?
Many thanks,
Martyn
