PLEBTracker: cmdbar.cpp:150:16: error: 'get_wch' was not declared in this scope

I am trying to add a Dockerfile to this project, to ease installation (you can try it out by just installing docker)

I am having trouble getting it to run with this Dockerfile:

FROM alpine:3.7

COPY . /usr/local/plebtrk
WORKDIR /usr/local/plebtrk

RUN apk add --no-cache alpine-sdk ncurses-dev fftw-dev alsa-utils inotify-tools
RUN cd ./Tracker/src && make && ./INSTALL.sh && cd ../../Interpreter/src && make && ./INSTALL.sh

ENTRYPOINT ["plebtrk"]

docker build .

make: *** [Makefile:23: ../obj/cmdbar.o] Error 1
The command '/bin/sh -c cd ./Tracker/src && make && ./INSTALL.sh && cd ../../Interpreter/src && make && ./INSTALL.sh' returned a non-zero code: 2

do I need to install ncurses differently in alpine, maybe?
