GNU/Linux Support?

[jaarac]

Do you plan to support GNU/Linux like SO?

[un1tz3r0]

i second this, some linux vsts we could use with eg bitwig would be really great

[PhysSong]

I've managed to build DDSP-VST on Arch Linux with the following changes. I'm not sure if all of them are really required, though.

If you get error: 'exchange' is not a member of 'std'(with GCC 12), try applying juce-framework/JUCE@ce8aff2 to external/JUCE.

@PhysSong You should make your changes into a PR, I would be glad to add the documentation part.
Your solution works well for me on Ubuntu 22 LTS.

[Taikakim]

Hmm this is very interesting. I've been trying it out through Yabridge now, and it seems to work not so well. The pitch tracking flips out a lot, and the UI is quite sticky. Also I can't figure out how to load in the models I trained.

So in that code red ones are to be removed and green ones added? But I think for me this is too complicated, I don't even know what all the prerequisites for compiling under Linux are... So I root for an official version too :)

[Mec-iS]

Hi,
there is not need to use emulation with Wine (that is what Yabridge does as far as I understood).
These are the prerequisites:

1. a real-time or low-latency kernel
2. Ardour or other native DAW
3. check that all the dependencies are installed on your system (missing libraries warnings are issued at compilation)
4. compile the plugin in your machine using the existing Makefile

So basically for 4.:

1. apply the changes to the files as specified above
2. Run make in the directory where the Makefile is, a compiled VST3 plugin is generated in the build directory.
3. Copy the plugin directory in the system's VST3 path

[Taikakim]

Ok, I will try that, I also heard just today that someone on the Linux Musicians FB group succesfully compiled this. I will try this out, thanks!

[Taikakim]

Hmm there is no Makefile, if I just run Git Clone on the repo, there is only the cmake directory, and running the repo-init script gives also errors. Also, I have no idea about what arguments to pass to cmake.

I have successfully compiled this on Debian 11. I followed the instructions and also made a few changes to add JACK support for the standalone. I could create a PR and send it over for review.

There were a few steps I needed to follow based on experience that were not in the instructions which I could also add.

I had a similar issue with trying to update the submodules where it constantly asked for SSH permissions, eventually they updated, as a failsafe, not sure if it helped or not, for JUCE and Tensorflow I manually cloned them over to the requisite locations.

I do have a question, would you mind if I hosted the Linux builds or would you like a copy of the binaries?

[Taikakim]

I'm interested in the binaries! :)

[KottV]

I'm interested in the binaries! :)

what is your distro? I packaged ddsp for opensuse tw https://build.opensuse.org/package/show/multimedia:proaudio/ddsp

[tank-trax]

@Taikakim for Linux Debian 11 available here

https://github.com/tank-trax/ddsp-vst/releases

also if you'd like me to submit a pull request... I also made changes to .gitmodules to bypass authentication request

cheers

[Taikakim]

Thanks for those! I've been busy so just now saw this!
