compile-python

This is a repo for compilling and installing Python from scratch

1. sudo apt-get update

2. sudo apt-get install build-essential gdb lcov libbz2-dev libffi-dev libgdbm-dev liblzma-dev libncurses5-dev libreadline6-dev libsqlite3-dev libssl-dev lzma lzma-dev tk-dev uuid-dev zlib1g-dev

3. go to python.org and get the latest prod release. I'll just use "Python 3.10.5" for now

4. Copy link address of "Gzipped source tarball"

5. wget https://www.python.org/ftp/python/3.10.5/Python-3.10.5.tgz

6. tar zxvf Python-3.10.5.tgz to uncompress the file

7. rm Python-3.10.5.tgz since it's no longer needed

8. cd Python-3.10.5

9. ./configure --enable-optimizations to configure optimizations, it creates the makefile

10. make -j 4 I have 4 cores in the Github Codespace instance, to compile on all 8 cores

11. sudo make altinstall, after this - Python is installed

12. python - You'll see the system python is still there, not the one we just installed

13. /usr/local/bin/python3.10 - will allow us to use it, however, on a new terminal session, it goes away

13b) To make it permanent on every new terminal session - nano ~/.bashrc

At the end of the bashrc file, add the below

---

#new python

alias python="/usr/local/bin/python3.10"

---

14. source ~/.bashrc - to activate or refresh the bashrc

15. Type python again to confirm - voila!

16. Create a virtual environment - python -m venv ~/.venv

17. Go back to bashrc file - nano ~/.bashrc

18. Add the below to the file

---

source venv

source ~/.venv/bin/activate

---

19. Run step 14 again - voila! - Always in your virtual environment with your newly installed python

20. sudo apt-get update

21. sudo apt-get install build-essential gdb lcov libbz2-dev libffi-dev libgdbm-dev liblzma-dev libncurses5-dev libreadline6-dev libsqlite3-dev libssl-dev lzma lzma-dev tk-dev uuid-dev zlib1g-dev

20. Might as well build out the whole scaffold

• touch requirements.txt
• touch Makefile

21. Could even install github copilot extension just for the project being worked on

22. git status
