Cannot install

[standerksen]

Using Python 2.7.14 on Windows 10, Ableton 9.5, running python setup.py install and getting:

cl : Command line error D8021 : invalid numeric argument '/Werror-implicit-function-declaration'
error: Setup script exited with error: command 'C:\\Users\\myusername\\AppData\\Local\\Programs\\Common\\Microsoft\\Visual C++ for Python\\9.0\\VC\\Bin\\cl.exe' failed with exit status 2

Edit: I've got it working after a tedious manual installation of pyliblo. However, now it cannot find my LiveOSC. I've tried both LiveOSC and LiveOSC2. Getting timed out waiting for server response on set.scan() in ex-clip-walk.py. Do I need to do anything else after selecting LiveOSC(2) as Control Surface in Ableton?

[ideoforms]

Unfortunately, changes in Live meant that LiveOSC was no longer compatible.
I've created a fork of LiveOSC which does work with Live 9.6/10:

https://github.com/ideoforms/LiveOSC

Select this as a control surface and it should work out of the box.

I really hate to comment in a closed issue for only this purpose, but I'm tearing my hair out...

@standerksen: What was involved in your "tedious manual installation of pyliblo"? That's where I am right now, and I'm getting nowhere (everything asks for MS Visual C++ 2014... which isn't available any more)... I strongly suspect that anyone trying to get this going on Windows will face issues.

EDIT: Maybe this? https://www.scivision.dev/python-windows-visual-c-14-required

[standerksen]

@tildebyte I'm sorry, of has been a while so I cannot remember. I did not end up using this version of pylive afaik.

[tildebyte]

@standerksen; Hey, no worries; I just thought I'd ask :)

[standerksen]

@tildebyte I think I built it from source on a UNIX based OS. So not sure if it's going to work on Windows.

[ideoforms]

Thanks for the feedback. I'll add an issue to look at replacing liblo with python-osc or oscpy, which are pure-Python implementations. My main concern would be in performance, as I know that liblo can handle large volumes of traffic and would need to verify that they can do the same.

Let me know if you have any success with liblo as I can add it to the readme.

[tildebyte]

@ideoforms - THAT WOULD ROCK. I really would like to try out pylive, particularly in conjunction with isobar, but I switched over to windows a little while ago, and haven't looked back, so the easy answer of "try it on a Mac" doesn't apply.

That said, this has been the worst software build nightmare I've encountered in a while. Nothing I do works right the first time, and so far I've only managed to hand-hack liblo and pyliblo - I still can't get the whole thing working...

[tildebyte]

EDIT: just woolgathering here, I don't know how hard it would be, but maybe one of the other python OSC libs could be a drop-in replacement for py/liblo with a bit of tweaking? Then users would have a choice.

[ideoforms]

Hmm, where does the build problem lie?
It does look like liblo is actively maintained with Windows support:
https://github.com/radarsat1/liblo
Might be worth speaking to the maintainer?

On the other hand, pyliblo hasn't been touched for a few years so that may have fallen out of sync.

[tildebyte]

I somehow managed to get liblo to build successfully using MSYS2, but regardless of the options I used, I couldn't get a DLL.

The pyliblo build process is nowhere near as simple as indicated, and in any case, pyliblo only seems to want to use the liblo which it builds anyway, so trying to build it oneself is pointless.

The major problem in all of this AFAICT is that pyliblo wants to build liblo using an outdated Visual Studio which I can't find for download anywhere.

Disclaimer; I know next to nothing about Visual Studio and its build procedures.

Hello friends! Could anyone help with the install? The first error I got was:

ModuleNotFoundError: No module named 'Cython'

then...
