Hi Brian,
What you need in the .bb is a runtime-dependency. RDEPENDS_${PN} += “
${PYTHON_PN}-flask ${PYTHON_PN}-jinja ${PYTHON_PN}-markdown” and so on. This
will add these modules in the root-filesystem and will be available on the
target.
If you need some basic help with a python recipe, there is a git repository
YoctoCookbook
https://github.com/yoctocookbook/meta-custom/tree/master/recipes-python/python-helloworld
to get you some idea.
Please not I am in no ways a Yocto expert on recipe creations but for the past
few weeks this is what I have been able to discover. Due to lack of examples on
custom recipes in python this is the best I can help you with.
Best Regards,
Shan

Betreff: [yocto] Installing Python app from source
I'm trying to install my own Python application from source, and having a hard
time finding resources on how to accomplish it. I'm new to this ecosystem and
am probably missing something fundamental.
My recipe is structured like this...and my build is configure such that it does
actually find it.
├── firmware-1.0
│ ├── saunders_backend
│ └── saunders_frontend
└── firmware_1.0.bb <http://firmware_1.0.bb>
My application code which is for now just a "hello world" flask application, is
in saunders_backend. The setup.py file in there works as expected when I use it
in on my host machine.
├── firmware-1.0
│ ├── saunders_backend/
│ │ ├── bin/
│ │ │ └── server
│ │ ├── MANIFEST.in
│ │ ├── requirements.txt
│ │ ├── saunders_apollo/
│ │ │ ├── config.py
│ │ │ ├── __init__.py
│ │ │ ├── models.py
│ │ │ ├── static/
│ │ │ ├── templates/
│ │ │ └── views.py
│ │ └── setup.py
│ └── saunders_frontend/
└── firmware_1.0.bb <http://firmware_1.0.bb>
I've been hacking on the .bb files to get it to install this into the resulting
image. I do have IMAGE_INSTALL_append = " firmware" in the top-level local.conf.
My primary confusion is that I don't know what I should be using for the python
application. do_install, do_install_append? What should SRC_UIR be? In effect
is that I want the exact same behavior of "cd saunders_backend && pip install
." My setup.py file has install_requires with a list of all dependencies, which
now is merely Flask.
Pointers would be appreciated.
BZ
