build failure on debian
this is an incredible project!
i'm having some difficulty with the initial build on debian bullseye and debian buster with the rust stable toolchain.
i've manually installed the latest stable of libportaudio system wide as suggested:
Package: libportaudio2
Version: 19.6.0-1.1
Package: libportaudiocpp0
Version: 19.6.0-1.1
I am able to build rust-portaudio from Git (which appears to be 0.7.0):
$ git clone https://github.com/RustAudio/rust-portaudio
$ cd rust-portaudio
$ cargo build --release
[...]
Finished release [optimized] target(s) in 26.70s
however, while building (linking) audioscope, i receive the following error:
/usr/bin/ld: /home/user/src/audioscope/target/debug/deps/libportaudio-779a6df6781f5d0f.rlib(pa_jack.o): in function `PaJack_Initialize':

happy to provide any other information you need. thanks for releasing this!
on debian buster, where libportaudio0=18.1 is available, i'm seeing a different issue which seems related to backtrace-rs:

i've tested with a few versions of the rust stable toolchain including:
stable-2020-11-16-armv7-unknown-linux-gnueabihf stable-2018-09-25-armv7-unknown-linux-gnueabihf stable-2020-02-27-armv7-unknown-linux-gnueabihf
https://github.com/conundrumer/audioscope/pull/19 fixes the build on debian/raspbian buster and possibly others by pulling in the latest version of backtrace-rs and some other transitive deps. the jack linker errors seem to be the same as https://github.com/RustAudio/rust-portaudio/issues/136 which has a workaround in https://github.com/RustAudio/rust-portaudio/issues/153
