I want to install the third-party tool called Mitmproxy in an embedded Linux environment with a low footprint, e.g. a Raspberry PI.
Rather than install using a standard Raspbian OS, I want to customize the install with Yocto and define the packages. This involves writing recipes to customize the packages that are installed. A good example at a high leve is described here.
Unfortunately this involves appending various Python3 packages as well pip-mitmproxy as well as all the dependencies of pip-mitmproxy in the local.conf file, e.g.
IMAGE_INSTALL_append = " python3"
IMAGE_INSTALL_append = " pip-mitmproxy"
Different recipe files need to be added in this case.
The challenge that I've found is getting the right versions of all the dependencies. I looked import pkg_resources but it doesn't seem to give me everything. Is there another recommended approach perhaps by looking at the source code.
I created Python venv on normal Linux Mint so pip freeze shows me empty list
After installing mitmproxy I run again pip freeze and it shows me

But it is hard to say if it needs some C/C++ libraries for this.
For example pyOpenSSL will need library OpenSSL but I can't find it in setup.py or setup.cfg. There is only information about openssl-devel which means it may need openssl.
It seems the only way is to install and run it to see error messages :)
