Compiling audio plugin host error

Linux
1

Hey,

I’ve recently made the switch to linux form windows and am trying to build the audio plugin host included in the extras. I believe I have all the necessary libraries as I had no problem building and running the Introjucer but for some reason I get this error when trying to build the audio plugin host.

I just updated from the 2.0.21 to the 2.0.22 code as well.

Thanks,

You need the latest version of the host codebase, which you clearly haven’t got.

Ahhh, I didn’t realize the Introjucer only updated the modules and not all the other goodies :oops: (even though it explicitly states it)
Thanks.

Yeah, I find that not ideal too. Especially that Introjucer doesn’t update itself (or does it now)?

Good point - I just never designed it to download anything other than the modules, all the other “extras” code is just a big bag of random stuff so doesn’t fit into that model.

Perhaps there should be two types of object: “modules” and “projects”? Then the introjucer could give you a list of all the available sample projects, and download them for you. (That might be interesting because it could also add 3rd-party apps to that list too). Hmm. I’ll ponder on this.
