How may I override the compiler (gcc) flags that setup.py uses by default?

阅读更多关于 How may I override the compiler (gcc) flags that setup.py uses by default?

问题 I understand that setup.py uses the same CFLAGS that were used to build python. I have a single C extension of ours that is segfaulting. I need to build it without -O2 because -O2 is optimizing out some values and code so that the core files are not sufficient to pin down the problem. I just need to modify setup.py so that -O2 is not used. I\'ve read distutils documentation, in particular distutils.ccompiler and distutils.unixcompiler and see how to add flags and libs and includes, but not

Post-install script with Python setuptools

阅读更多关于 Post-install script with Python setuptools

Is it possible to specify a post-install Python script file as part of the setuptools setup.py file so that a user can run the command: python setup.py install on a local project file archive, or pip install <name> for a PyPI project and the script will be run at the completion of the standard setuptools install?

I came across this SO answer from several years ago that

What is setup.py?

问题 Can anyone please explain, what is setup.py and how can it be configured or used? 回答1: setup.py is a python file, which usually tells you that the module/package you are about to install has been packaged and distributed with Distutils, which is the standard for distributing Python Modules. This allows you to easily install Python packages. Often it's enough to write: $ pip install . pip will use setup.py to install your module. Avoid calling setup.py directly. https://docs.python.org/3
