build binary eggs for linux-armv6l (raspberry pi)

[zooko]

This is one of a collection of tickets about binary eggs that need to be built for specific platforms.

See src/allmydata/_auto_deps.py for Tahoe-LAFS trunk's current dependencies, and ​https://tahoe-lafs.org/source/tahoe-lafs/deps/tahoe-dep-eggs/README.html for the eggs that have been built and uploaded.

From #804, if someone builds binary eggs of the dependencies for linux-armv6l, that would make it easier and faster to install Tahoe-LAFS on raspberry pi.

It is currently missing all eggs, and I think we just need to support Python 2.7.

Here are instructions for how to build binary eggs:

Hmm.. i tried but get an error:

python -c "import setuptools; execfile('setup.py')" bdist_egg
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "setup.py", line 24, in <module>
basedir = os.path.dirname(os.path.abspath(file))
NameError?: name 'file' is not defined

My knowledge of python is next to zero, so a foolproof cut and paste line to build this egg would be great

Kind regards,
Ed

Try this:

python -c "import setuptools; __file__ = 'setup.py'; execfile('setup.py')" bdist_egg

Hang on, that line is only necessary for pycrypto. The other eggs should be built using:

python setup.py bdist_egg

[kapiteined]

made with: python setup.py bdist_egg

Worked like a charm, the egg file from both commands are attached, the original name was:
dist/allmydata_tahoe-1.10.0-py2.7.egg

Could someone change the Packaging page to include the right commands?

Thanks, kapiteined and daira! kapiteined: what's your name and contact info, and what computer did you build it on, and what operating system was it running? Thanks again!

Hi Zooko, my e-mail address is ed AT kapitein DOT org.
It was build on the pi itself running rasbian, updated to the latest version about a week ago.

Feel free to contact me to try out a release candidate for the pi package.

That's an egg for Tahoe itself, which we don't actually need. We need the eggs for Tahoe's dependencies that use C/C++ code, which are the 6 table columns at ​https://tahoe-lafs.org/source/tahoe/deps/tahoe-lafs-dep-eggs/README.html:

• ​Twisted (use the source tarball)
• ​pyOpenSSL
• ​pycrypto
• ​pycryptopp
• ​zfec
• ​zope.interface

Will do.

Done.

pyOpenSSL seems to need the "long" packaging command as well:

python -c "import setuptools; file = 'setup.py'; execfile('setup.py')" bdist_egg

Fixed in Packaging.

Okay, I'm officially closing all tickets that have to do with binary eggs on Linux as wontfix. Binary eggs have never worked on Linux, and never will. I hate this, but I hereby stop struggling against it.

[daira]

It might be useful to maintain these eggs for Raspberry pi because it's difficult to compile them on the pi.

[warner]

I'm +1 on hosting ARM eggs. I've got an rPi lying around, I could probably build them if I get some free time.

[daira]

The necessary eggs are already attached to this ticket, aren't they?

[exarkun]

We have since stopped CI for Raspberry Pi/ARMv6l. Also eggs are probably obsolete at this point (a similar ticket might be filed about wheels, if Raspberry Pi/ARMv6l again becomes a supported platform).
