I am struggling with the support for python for MariaDB in Fedora 37.

I did:
$ sudo dnf install python-devel mariadb-connector-c-devel mariadb-connector-c mariadb-devel python3-pip
$ python3 -m venv venv
$ source venv/bin/activate
(venv)$ pip3 install mariadb

Error message:

Collecting mariadb
  Using cached mariadb-1.1.5.post3.tar.gz (82 kB)
  Installing build dependencies ... done
  Getting requirements to build wheel ... error
  error: subprocess-exited-with-error

[notice] A new release of pip available: 22.2.2 -> 22.3.1
[notice] To update, run: pip install --upgrade pip

It seems that MariaDB Connector/C >= 3.3.1 is required.
From https://mariadb.com/downloads/connectors/connectors-data-access/c-connector/ I see downloads for manual installation for different OS but not for Fed37.

How to solve this?

Any help is appreciated.

You can’t install a newer version than Fedora has built, but you can install an older version of the Python package. The previous version appears to work:

$ pip3 install mariadb==1.1.4
Collecting mariadb==1.1.4

Using legacy 'setup.py install' for mariadb, since package 'wheel' is not installed.

    Uninstalling mariadb-1.1.2:

  Running setup.py install for mariadb ... done
Successfully installed mariadb-1.1.4

(Note, you also need to dnf install gcc if you haven’t already.)

Mariadb is available for direct install from the fedora repo

# dnf list mariadb

It is not necessary to install it piecemeal with python or pip.

That is the database itself, not the Python connector library.

Answer is simply here : https://mariadb.com/resources/blog/how-to-connect-python-programs-to-mariadb/. Python is a scripting language, MariaDB a database …

For what it’s worth, I normally just use the MySQL driver in Python with MariaDB:

sudo dnf install python3-mysqlclient

Here are the docs for this driver:

Thanks.

mariadb==1.1.4

is the trick. This is working for me in Fed36 and Fed37.
