Build fails due to unavailability of PortAudio dependency download

[Michael-Z-Freeman]

Hi. This is a long standing problem with www.portaudio.com that was supposed to be fixed in August ( PortAudio/portaudio#634 ). This issue is also reported out there for Audacity and other projects. Archive.org has no (or very few) pulls of www.portaudio.com since August and there are loads before the problem arose.

To fix I just found another copy of the library referenced in the Makefile, uploaded to my site, and changed the link in the Makefile to https://files.michaelzfreeman.org/pa_stable_v19_20140130.tgz and the build completes successfully. Developers/users can temporarily use that link if they want to but probably not a good idea to actually put it permanently in the Github version of the Makefile. Cheers.

What platform are you building zynaddsubfx on?

[Michael-Z-Freeman]

Linux (Ubuntu).

For the moment everything should be working. This issue does highlight that we're using a pretty old version of portaudio. There isn't exactly a ton to the interface that I would have expected to change over the years, but updating the pull to something like https://github.com/PortAudio/portaudio/archive/refs/tags/v19.7.0.tar.gz would update that code as well as pull from a source less likely to have uptime issues.
