Notes to install Python 3.12
- Download Python 3.12 source from the official website
- Extract the files
- Configure the files wih optimization enabled
./configure --enable-optimizations- Generate installation script
make
- If it reported that it is missing some dependencies, it is recommended that you install what's suggested by the report. You can install the necessary packages that you are familiar with or maybe you can install as many packages as possible that are available in openSuse repository. Note that the packages required are development files. So for example the report stated it requires
curses, then it meanscurses-devorlibcurses-dev(naming is for context example).
Special case for _ctypes, you need to install libffi-dev. This package is used for testing
- Install to system as global
sudo make install
- Don't forget to create symbolic link from lib64 to lib. Otherwise, we will get an error if we try to create a venv
sudo ln -s /usr/local/lib64/python3.12/lib-dynload /usr/local/lib/python3.12/lib-dynload
The error if we don't create the symlink:
python3.12 -m venv venv
Could not find platform dependent libraries <exec_prefix>
