    I can't remember all the little differences between the various Ubuntu flavors.

    Albert has a repo for xubuntu here. You could give it a shot using the instructions here:


    If you get dependency errors after apt install purr-data it means we'll have to compile specifically for Ubuntu Studio. Otherwise you should have a fully working install.

    What version of Ubuntu Studio?

    @ddw_music It's not necessarily difficult. I've just gotten a lot of ways to get Gem up and running which aren't really maintainable. Part of the problem with Pd Extended was that there were too many hacks to get it compiling on each platform. I want to avoid those problems as much as possible in Purr Data.

    That might offset some of the feeling that the documentation isn't there yet.

    I'm not sure how that affects the documentation/lack of documentation.

    Would it be any more or less work just to make it loadable in Purr Data?

    It's the same amount of work either way. But the payoff for that work is smaller if the documentation/usability isn't there.

    Edit: however, don't let me stop anyone from testing it with Purr Data. And if there are bugs in Purr Data that keep it from working with Ofelia please post an issue to the issue tracker.

    Thanks for the feedback. I've been impressed with what has been posted on the forum about it, and I was trying to figure out if I should attempt to bundle Ofelia with Purr Data. But it sounds like I should probably wait until the documentation/interface becomes more solid.

    Glancing at the code I see sevy copy/pasted a few non-public header files from the lame mp3 library. It appears that those libraries haven't really changed their structure but I'm not absolutely sure.

    Also, I see one piece of the copy-pasta (interface.h) has some duct-tape that ends up recursively calling itself. Legal, but weird.

    So your crasher could have to do with running as a 64-bit binary, the fingerpainting dependency copy/pasta, or something else entirely.

    I'm actually not able to instantiate it on my Chromebook because it can't find any of the symbols from the header copy/pasta. But I see those symbols in the lame library guts so I'll try static linking later and see what happens.

    Is Ofelia a replacement for Gem?

    Is it possible for a user create easy to moderate projects by only using Pd objects? In other words, can a user get work done it it without learning any new languages?

    @60htz It has been merged for awhile. I just haven't done a release yet.

Internal error.

Oops! Looks like something went wrong!
