Description

Attempting to build the mariadb-connector-python version 1.1.10 results in a compilation error related to incompatible pointer types in the C extension code. The build process fails when compiling the _mariadb extension, specifically in the mariadb_cursor.c file.

Command:

pip install ./mariadb-connector-python-1.1.10

Output:

  ERROR: Failed building wheel for mariadb

Failed to build mariadb

ERROR: ERROR: Failed to build installable wheels for some pyproject.toml based projects (mariadb)

Cause: The error indicates a type mismatch in the C extension code where a

const char **

is being passed to a function that expects a

char **

. This might be due to stricter type checking in Python 3.12 or changes in the Python C API.

Suggested Fix
Package installed successfully after changing line 1128 of 'mariadb/mariadb_cursor.c' from

const char *statement;

char *statement;
