How to compile Python extension with debug info using PIP

Question

I have source code for an extension in Python. I want to see debug symbols for that extension when I debug it. How do I tell PIP to compile and link debug symbols for my extension?

(Preferably platform agnostic, else Linux)

You need to invoke setup.py's build command with --debug flag during package installation. Using pip additional flags to setup.py can be passed using --global-option:

pip install --no-binary :all: --global-option build --global-option --debug PACKAGE

In case of errors try upgrading pip and setuptools:

pip install -U setuptools
pip install -U pip
