Has anybody tested if this works with Ubuntu 18.04? #1

Closed hmaarrfk closed 4 years ago

hmaarrfk commented 5 years ago

My Ubuntu 18.04 builds seem to fail with

ImportError: libudev.so.0: cannot open shared object file: No such file or directory

I think it is because ubuntu uses libudev1 and we have compiled with libudev0

edisongustavo commented 5 years ago

Yes, I've noticed the same thing on Ubuntu 19.04.

As it is, this package should not be used on these platforms.

Would packaging libudev be a solution?

hmaarrfk commented 5 years ago

depends on how much of the kernel it depends on right. we can try. But not sure.

hmaarrfk commented 5 years ago

I think libudev got moved into systemd, we would have to think about how to integrate systemd into conda forge.

I don't know if that makes much sense to be honest.

hmaarrfk commented 5 years ago

right, honestly, on my laptop i just simlinked libudev.so.0 and libudev.so.1, but i know that is bad....

Does this help?

For ubuntu 14.04 and above

The easiest method I found was to just download the .deb (direct link to 64-bit download and to 32-bit download) and double click it to install it or use dpkg to install it:

dpkg -i libudev0_175-0ubuntu9_amd64.deb

See also https://unix.stackexchange.com/questions/156776/arch-ubuntu-so-whats-the-deal-with-libudev-so-0

Says there,

It's possible to build an older version of libudev that still provides .so.0 if it's necessary.

Maybe that's what we should focus on?

edisongustavo commented 5 years ago

But would it work if I use a libudev.so.0 on the newest Ubuntu?

hoechenberger commented 5 years ago

I don't know; the SO answer seems to imply that it should work!

hmaarrfk commented 5 years ago

I think it does work, my fear is that it is a little complicated to install.

This might also be the first of many issues regarding low level access to hardware with conda-forge that will pop up.
