The libjack-dev package is installed.

Steps to build:
$ git clone https://github.com/RustAudio/synth
$ cargo build --example test

error: linking with cc failed: exit code: 1

Then there follows about 80 errors like this sample:
.cargo/registry/src/github.com-1ecc6299db9ec823/portaudio-0.6.4/portaudio/src/hostapi/jack/pa_jack.c:1738: undefined reference to 'jack_frame_time'

Traced the error to portaudio, by trying to build it in .cargo/registry/src/github.com-1ecc6299db9ec823/portaudio-0.6.4, which resulted in the same linker errors. Turnes out there is a dependency on Ubuntu package portaudio19-dev which is not detected by the cargo installation process. Installing that package resolved the linker problems.

Have raised the issue in portaudio.
