I also installed tkinter in fedora but its version is 3.11.6.

Answer 1

Update your system's package list and install the required packages

sudo dnf update
sudo dnf install tk-devel

Set the TCL_LIBRARY and TK_LIBRARY environment variables. You can do this in your shell configuration file (e.g., ~/.bashrc or ~/.zshrc) or set them temporarily for your session. Replace <path_to_tcl> and <path_to_tk> with the actual paths

export TCL_LIBRARY="<path_to_tcl>/lib"
export TK_LIBRARY="<path_to_tk>/lib"

Open a new terminal to apply changes

pyenv install 3.12.0

This should allow you to build Python 3.12.0 with Tkinter support
